The Darwin Palm is a slender palm that grows up to 12 metres high. It has multiple green trunks that are only 3-6 centimetres wide, and feathery fronds with leaflets that grow up to one and a half metres long. Flowering spikes are produced in the dry season, from April to August, with the main fruiting period between August and December.

A sparse, clustering palm, of the monsoon forest depths, up to 12 tall, its long thin green stems, 3-6 cm in diameter frequently 'hang about' amongst other vegetation for support, or simply fall on the ground. Pinnae are evenly arranged on the few flat leaves, rising from a green crownshaft. Red fruit are very few and ripen sporadically, even cultivated specimens yield a scant handful at a time.

De-fleshed and planted in shallow trays, their germination rate is excellent, seedling appearing in 4 or 5 months. Standard horticultural practice suits P. bleeseri, a slow release fertilizer can be given at every move to a larger pot. Two years growth in the nursery area produces a 1.5 m suckering specimen, its dark green pinnae lying flat and even up the rachis. Sun hardened palms can be planted in almost full sun, a much shorter, robust plant will result. Three or more mature stems and many basal suckers are common in cultivated specimens. Irrigation, fertilizer and mulch are necessary. Cold Hardiness Zone: 10b

"Ptychosperma bleeseri is known from only eight small monsoon rainforest patches, located in the vicinity of Darwin, Australia. One population consists of only one adult plant and only one patch contains a population of more than 50 adult plants. A survey of the genetic diversity within the species was undertaken using isozyme analysis. Almost no genetic variation was recorded. Of the 223 wild collected samples tested, only four individuals varied at a single locus out of the 10 loci analyzed. The lack of diversity among populations suggests that the existing populations are derived from a common, genetically depauperate, source which has acted as a founder population. P. bleeseri was compared with the other Ptychosperma species which occur naturally in Australia (P. macarthurii and P. elegans). Each of these species was found to differ consistently at several enzyme loci thus indicating that P. bleeseri does not simply represent an outlying population of either of these two species. Cultivated specimens of P. bleeseri were shown to have hybridized with other cultivated Ptychosperma species when grown together. This presents a problem for ex-situ conservation. Since palms are particularly favoured by Darwin residents in their gardens and public places, the location of urban development in close proximity to wild populations of P. bleeseri has the potential to introduce other Ptychosperma species into the wild populations. This could have serious effects on the genetic integrity of the species." (Dr. Alison Shapcott)

"Ptychosperma bleeseri is known from only a few specimens growing near Darwin. The habitat has been decimated by feral pigs and buffalo and the area has been fenced off in an attempt to save the remaining individuals. The species is clumping, similar to P. macarthurii but is less robust looking than that species and when grown in shade has very thin trunks that tend to lean against the canopy trees for support. It is much more robust when grown out in a more open position. What I can\'t believe is how fast it grows, mine is only young but it is still growing a lot faster that any other Ptychospermas I have and a mate of mine had his mature and fruit from seedling size in only 4 years! It is still very restricted in cultivation, even here in Australia. When mine does fruit I might be able to forward some seed to the U.S. to see how it performs in Florida."

P. bleeseri make excellent indoor plants, actually growing in dark air-conditioned offices and fume-filled beauty salons. Since the rediscovery of Ptychosperma bleeseri, concerted efforts have resulted in many specimens around suburban and rural gardens.
  
 
Conservation: The recognized threats to P. bleeseri or its habitat include wildfire, introduced animals (buffalo Bubalus bubalis, cattle Bos indicus, pigs Sus scrofa), weeds (Duff et al. 1992) and hybridisation with ornamental Ptychosperma species introduced to gardens in the local area (Shapcott in press). Illegal harvesting is no longer a problem.  Factors likely to be important in the long term, but less clearly understood, include: changes in the quality and quantity of groundwater through extractive mining, horticulture and rural residential subdivision (Liddle et al. 1996).

Habitat and Distribution

The Darwin Palm is only found in eight small rainforest patches east of Darwin,
Ptychosperma bleeseri in the wild. These are growing in the Darwin area, in areas where there is permanent moisture. They occur alongside Carpentaria acuminata and Livistona benthamii in rainforest patches. This particular stand was in the Howard Springs area just south of Darwin, but still in the outer suburbs. Photo by Daryl O'Connor
within the Adelaide and Howard River system. It occurs over an area 30 kilometres long by 20 kilometres wide. Three of the eight rainforest patches occur within the Black Jungle Conservation Reserve, with the remainder occurring on freehold or pastoral lease land.

Description

The Darwin Palm is a slender palm that grows up to 12 metres high. It has multiple green trunks that are only 3-6 centimetres wide, and feathery fronds with leaflets that grow up to one and a half metres long. Flowering spikes are produced in the dry season, from April to August, with the main fruiting period between August and December. (Australian Government Department of the Environment)

A sparse, clustering palm, of the monsoon forest depths, up to 12 tall, its long thin green stems, 3-6 cm in diameter frequently 'hang about' amongst other vegetation for support, or simply fall on the ground. Pinnae are evenly arranged on the few flat leaves, rising from a green crownshaft. Red fruit are very few and ripen sporadically, even cultivated specimens yield a scant handful at a time.

Culture

De-fleshed and planted in shallow trays, their germination rate is excellent, seedling appearing in 4 or 5 months. Standard horticultural practice suits P. bleeseri, a slow release fertilizer can be given at every move to a larger pot. Two years growth in the nursery area produces a 1.5 m suckering specimen, its dark green pinnae lying flat and even up the rachis. Sun hardened palms can be planted in almost full sun, a much shorter, robust plant will result. Three or more mature stems and many basal suckers are common in cultivated specimens. Irrigation, fertilizer and mulch are necessary. Cold Hardiness Zone: 10b

Comments and Curiosities

Ptychosperma bleeseri is a slender clumping palm endemic to rainforests in the Northern Territory of Australia and is listed as nationally endangered (EFN 1993). The species is known from eight rainforest patches all of which are wet, spring fed forests located on the margin of the Adelaide River floodplain or on the Howard River system to the east of Darwin (Barrow et al. 1993). The extent of the species range is 30 km long by 20 km wide and the total area of occupancy is 40 ha.

"Ptychosperma bleeseri is known from only eight small monsoon rainforest patches, located in the vicinity of Darwin, Australia. One population consists of only one adult plant and only one patch contains a population of more than 50 adult plants. A survey of the genetic diversity within the species was undertaken using isozyme analysis. Almost no genetic variation was recorded. Of the 223 wild collected samples tested, only four individuals varied at a single locus out of the 10 loci analyzed. The lack of diversity among populations suggests that the existing populations are derived from a common, genetically depauperate, source which has acted as a founder population. P. bleeseri was compared with the other Ptychosperma species which occur naturally in Australia (P. macarthurii and P. elegans). Each of these species was found to differ consistently at several enzyme loci thus indicating that P. bleeseri does not simply represent an outlying population of either of these two species. Cultivated specimens of P. bleeseri were shown to have hybridized with other cultivated Ptychosperma species when grown together. This presents a problem for ex-situ conservation. Since palms are particularly favoured by Darwin residents in their gardens and public places, the location of urban development in close proximity to wild populations of P. bleeseri has the potential to introduce other Ptychosperma species into the wild populations. This could have serious effects on the genetic integrity of the species." (Dr. Alison Shapcott)

"Ptychosperma bleeseri is known from only a few specimens growing near Darwin. The habitat has been decimated by feral pigs and buffalo and the area has been fenced off in an attempt to save the remaining individuals. The species is clumping, similar to P. macarthurii but is less robust looking than that species and when grown in shade has very thin trunks that tend to lean against the canopy trees for support. It is much more robust when grown out in a more open position. What I can\'t believe is how fast it grows, mine is only young but it is still growing a lot faster that any other Ptychospermas I have and a mate of mine had his mature and fruit from seedling size in only 4 years! It is still very restricted in cultivation, even here in Australia. When mine does fruit I might be able to forward some seed to the U.S. to see how it performs in Florida."

A very attractive and highly endangered palm from rainforests in Australia's Northern Territory with slender, clustering, grayish stems, each topped by a rather sparse crown of pretty, glossy green leaves with leaflets that have fishtail-shaped tips. Leaflet width is intermediate between P. propinquum and P. macarthurii. (RPS.com)

P. bleeseri make excellent indoor plants, actually growing in dark air-conditioned offices and fume-filled beauty salons. Since the rediscovery of Ptychosperma bleeseri, concerted efforts have resulted in many specimens around suburban and rural gardens.

Conservation: The recognized threats to P. bleeseri or its habitat include wildfire, introduced animals (buffalo Bubalus bubalis, cattle Bos indicus, pigs Sus scrofa), weeds (Duff et al. 1992) and hybridisation with ornamental Ptychosperma species introduced to gardens in the local area (Shapcott in press). Illegal harvesting is no longer a problem. Factors likely to be important in the long term, but less clearly understood, include: changes in the quality and quantity of groundwater through extractive mining, horticulture and rural residential subdivision (Liddle et al. 1996).

Here's how you can help the Darwin Palm and other threatened species:

join a local community group and undertake on-ground conservation work; control weeds on your property or nearby native bushland; get involved in regional planning to ensure that proposed developments do not impact on threatened species.
