Juty-AucusT, 1918.} THE ORCHID REVIEW. 181 
It seems probable that Mr. Powell will be able to increase our knowledge 
of the Orchids of Panama, of which, according to an enumeration of 
Central American Orchids in the Biologia Centrali-A mericana, some 104 
species are known. These were largely extracted from Reichenbach’s 
account of the Orchids collected by Warscewicz, chiefly in the Chiriqui 
district, some of which are still unrecorded from elsewhere, and may be 
endemic. According to this enumeration, seven species of Sobralia occur 
in Panama. And four species of Cynoches have been described from there, 
C.aureum, Lindl., C. Diane, Rchb. f., C. ventricosum, Batem., and C. 
Warscewiczii, Rchb. f. C. aureum is a very handsome yellow-flowered 
species of which nothing seems to be known but the original specimens, 
which are preserved in Lindley’s herbarium, and it is suspected that C. 
Warscewiczii may be the female of the same. We hope that Mr. Powell 
may be able to obtain additional materials of so strikinga plant. Epidendrum 
Pseudepidendrum, Rchb. f., is another striking Chiriqui species, with green 
sepals and petals, and bright red lip. Selenipedium Chica, Rchb. f., one 
of the three species of a small genus with Sobralia-like habit, is also a 
native of Panama, and, according to Reichenbach, possesses fruits that are 
highly aromatic, and are used by the inhabitants of the isthmus in the same 
way as Vanilla, hence the native name of Vainilla chica, or little Vanilla. 
There is evidently much of interest in the Orchids of Panama.

Poste brevispatha seems to be our common deciduous species, 
growing and flourishing under conditions which would soon prove fatal 
to L. leucantha, a shade and moisture-loving species occuring chiefly in 
ravines on the Atlantic slope at 2000 to 4000 feet ; often terrestrial, or rather 
it is one of those species which if torn from their natural position by wind 
thrive happily on the ground. L. brevispatha, of which L. candida is 
Probably a geographical form, is a very variable species, and those growing 
under the shadiest conditions seem to have the most heavily-marked flowers. 
The generality here have quite pale flowers, and are often grown on tile 
toofs, or on the tops of old walls, and are remarkably floriferous under such 
Conditions. This species occurs wild a short distance north of Cartago, but 
is getting scarce there. South of San José, Candelaria hills, it is still 
abundant. Of L. leucantha I found a plant last week with leaves 264 inches 
long by 74 inches wide and bulbs to correspond. L. brevispatha never 
attains such dimensions, 12 to 16 inches being the average length of leaves, 
and it has sharply bimucronate bulbs, those of L. leucantha being unarmed.
