MISSOURI BOTANICAL GARDEN BULLETIN 33 
ORCHID DISPLAY 
The nun orchid (Phaius grandifolius), mentioned in the 
December BuLLETIN, is well represented among the flowering 
orchids. The four plants exhibited are bearing eleven spikes, 
with an aggregate of two hundred brownish white flowers. 
The plants are terrestrial in their habit, and are indigenous 
to the moist regions of Asia and Australia. Under green- 
house culture they require a treatment entirely different 
from that of the epiphytes, e. g., the cattleyas. Instead of 
being grown in peat and moss, they are grown more like the 
palms, in rich, loamy soil, and treated with organic fertilizers 
before their flowering period. The plants grow continu- 
ously, no resting period being required as in the majority 
of orchids. Spathoglottis aurea Vieillardi, bearing a solitary 
spike of light yellow flowers, is also terrestrial in its habit. 
It requires only a partial rest after flowering. The variety 
at present in bloom is of garden origin, being a cross between 
S. aurea and S. Vieillardi. 
The cattley orchid (Cattleya Trianaei), with its large 
mauve flowers, is still represented by several good specimens. 
Luddemann’s orchid (Cattleya Luddemanniana), closely 
resembling the cattley orchid, is also in flower. The braided 
orchid (Lockhartia pallida), a native of the Panama region, 
has several spikes of delicate, white flowers. Its most inter- 
ie feature is the braided appearance of the long, thin, 
at leaves. 
Oncidium is a genus variable in the foliage of its species. 
The baby’s bonnet orchid (Oncidiwm luridum), with long 
pendant spikes of brownish flowers, has large leathery leaves, 
whereas the fan orchid (Oncidium iridifolium), with light 
yellow flowers, has its leaves equitant, resembling a small 
fan in their arrangement. Oncidium Cebolleta and Onci- 
dium stipitatum are entirely different in their foliage. In- 
stead of having large, leathery, or small, fan leaves, 
they bear long needle-like leaves. The flowers are small and 
yellowish, somewhat resembling those of the fan orchid. 
Oncidium splendidum has large yellow-lipped flowers on tall 
upright spikes. The leaves, which are attached to prominent 
peendobulbs, are very rigid and of a brownish color. 
The Schomb ’s orchid (Schomburgkia undulata), a 
native of Venezuela, is producing two | spikes bearing 
clusters of dark purple flowers. The sepals and petals are 
undulate, giving a crested appearance. The collection of 
slipper orchids is nopneieetaa be upwards of twenty varieties
