TROPICAL AMERICAN ORCHIDS 
Dichaea verrucosa is unusual on account of its dorsally 
muricate sepals and petals. The only one of its allies with 
this characteristic apparently being D. suaveolens Kranzl., 
which, however, has much-branched stems, smaller and 
much narrower leaves, obovate-oblong petals, and differ¬ 
ently colored flowers. D. muricata (Sw.) Lindl. is superfi¬ 
cially very similar, but has smaller flowers, narrower petals, 
and apparently lacks the ligulate column-appendage. 
Costa Rica, La Fuente, Peralta, C. H. Lankester 918, 
September 1923. 3800 feet altitude. Sepals and petals hya¬ 
line spotted “dark violet,” margin of lip frontally stained 
violet, rest heavily blotched with violet, sepals exteriorly 
rugulose. The young leaves are mucronate. A common and 
beautiful species. (Type in Herb. Ames No. 28692.)
