TROPICAL AMERICAN ORCHIDS 
This remarkable plant is probably the species that 
Schlechter refers tentatively to Dipierostele minutiflora 
(Kranzl.) Schltr. in Fedde Repert. Beihefte 19 (1923) 70. 
However, it is apparently not the Telipogon minutifiorus 
Kranzl. as described in Ann. Naturhist. Hofmus. Wien 33 
(1919) 14. Moreover, Kranzlin’s description was prepared 
from poor material, so there is some doubt regarding the 
exact status of his species. The Costa Rican material differs 
in several points from the genus Dipterostele as erected by 
Schlechter on an Ecuadorean plant (Fedde Repert. Beihefte 8 
(1921) 106), as is indicated in Fedde Repert. Beihefte 19, p. 70. 
In floral structure at least Stellilabium distantiflorum 
appears to agree fairly well with S. astroglossum (Reichb. f.) 
Schltr. (Orchideen (1914) 530) based on Telipogon astro- 
glossus Reichb. f., which is illustrated in Xenia Orchidacea 
1 (1854) t. 7. [Plate 21: habit life size. 1, flower X 4. 2, col¬

lanceolate or oblong; petiole short, stout, conduplicate,
