POGONIA PACHYSTOMOIDES. Native of Queensland. 
Stems 9 inches high and slender, with a few minute flowers, the labellum thin 
and translucent. 
POGONIA UNIFLORA. Native of North Queensland. 
Like the other species, this has very slender stems about 6 inches tall with a few 
sheathing scales. Flowers half an inch long. The three-lobed lip has its middle 
lobe contracted at the base, and the disk has a fleshy line at the base. 
PLEUROLALA Linke 
A large genus of epiphytical orchids, few of whose species are of horticultural 
value, though some of them are beautiful and have flowers of fair size. Like so 
many of the South American orchids, they do not travel well. However, one 
occasionally sees a plant or so of Pleurothallis in Australia, and only a year or 
so ago a few plants were available in Sydney. They do best in teak baskets in a 
compost of peat or polypodium fibre, with a little leaf-mould, dried cow-dung 
and pulverised brick added. In the warmer parts of Brisbane an open bushhouse 
will serve, particularly in the Summer months. But, where the Winter tempera- 
ture falls below 50° for any length of time, they should be moved under glass 
for that season. Plenty of water must be applied during the warmer part of the 
year, but during Winter the plants must be kept comparatively dry. The best 
species are:— 
PLEUROTHALLIS ORNATA. Native of Colombia. 
A small growing orchid which grows in clusters of short stems springing from a 
stout rhizome. They are crowned with a small oval, fleshy leaf about an inch 
long. Flowers solitary and about half an inch in diameter. Sepals and petals 
pale purplish-brown, the sepals having a prominent fringe of white tendrils 
which wave at the slightest stir of the plant or the air about it. Flowers late 
Spring and lasts three to four weeks. 
PLEUROTHALLIS PUNCTULATA. Native of Colombia. 
The most attractive species, with 2-inch stems topped with stiff, leathery, lanceo- 
late-oblong leaves, 3 inches to 34 inches in length. Sepals and petals honey- 
coloured, dotted with purplish-brown. Top sepal rhomboidal, pointed and erect. 
Lateral sepals spreading, united at the base. Lip a beautiful deep maroon, the top 
being papillose (é.e., furnished with a number of nipple-like protuberances). 
Flowers Summer, lasts three weeks.
