THE EVOLUTION OF THE ORCHIDACE, 
(Continued from page 294.) 
Tue interesting subtribe Stanhopiez follows Cyrtopodiez, and now includes 
a few genera which had been placed in the latter group and elsewhere by 
Bentham. Catasetide, however, which had been included by Bentham, is 
here considered distinct. Stanhopiez forms a very natural group, and 
includes a large number of showy garden species. The plants are epiphytes, 
with ovoid, often large pseudobulbs, terminating in one or few, usually 
large, plicate or prominently ribbed leaves. The scapes are leafless, 
pendulous or sometimes erect, often with rather large flowers, and the lip 
fleshy, sometimes very complex in structure, but without a spur. The 
pollinarium has generally a well-developed slender stipe. The group is 
exclusively American, ranging from Mexico to Peru and South Brazil, and 
as here defined contains about 17 genera and over 130 known species. The 
line of demarcation between Stanhopiee and Cyrtopodiez is not easy to 
define, but is best drawn so as to include Lacena, Lycomorium and 
Gongora in the former. Cirrhza, placed by Bentham in Notyliez, is also 
more nearly allied to Gongora, while Stenia and Schlimmia are out of place 
among the Maxillariez. 
Stenia has a distinct foot to the column, to which the lateral sepals are 
united, forming a pouch, which encloses,the fleshy saccate lip, the latter 
having fringed teeth at the base, recalling those of Sievkingia. Two or three 
species are known, natives of Guiana and Colombia. Schlimmia has alsoa 
foot to the column and a saccate base to the lateral sepals, and contains 
about three Colombian species, which are seldom seen in cultivation. 
Ceeliopsis contains a single species from Panama, and bears buff-coloured 
flowers in short rounded heads, and is obviously allied to the preceding 
genera. Reichenbach regarded it as near Sievkingia. Kegelia is an 
imperfectly known genus, a native of Guiana, said to be allied to Laczna. 
Sievkingia, which apparently contains Gorgoglossum, Lehm., consists of 
about four species, natives of Costa Rica, Colombia and Guiana. The 
flowers are borne in short descending racemes or heads, and the flowers are 
yellow and rather membranous, with a saccate lip, or in one case a fringed
