Description

Mountain xylosma is a shrub that grows to 2 m in height. Its leaves are rounded, 12 mm long by 8 mm wide, with toothed margins. The fruits are globular, purple and 5 mm in diameter; they are eaten, and the seeds dispersed, by birds.[2]

Distribution and habitat

The plant is largely restricted to low shrub vegetation growing on narrow, exposed, southeasterly or southwesterly ridges off the two mountains – Mounts Lidgbird and Gower – in the southern part of the island. The known range lies within Lord Howe's Permanent Park Preserve.[2]

Status and conservation

Fewer than 100 mature plants are known and, extrapolating to suitable habitat, fewer than 250 mature plants are likely to exist in the wild. Because of its small population size, limited habitat and susceptibility to environmental and demographic stochasticity, the species is listed as Endangered under New South Wales’ Threatened Species Conservation Act 1995.[1]

gollark: My bot has about 300 lines of code, and it has... a fortune command, `++delete` (a joke one which just says "Deleted [whatever you typed]" and adds it to the deleted items list), a command to list recently "deleted" things, a command to run various esolangs and stuff using TIO.run, and a reminder thing.
gollark: Many of them *are* pretty similar.
gollark: I mean, kind of? Most of the complex Discord interaction logic is done by discord.py or whatever you use, but you do still have to program the commands.
gollark: Python with discord.py is good. My bot uses it and... mostly works.
gollark: Making a Discord bot or whatever it is you want requires a lot of learning things before you get much of a bot.
