4. Didissandra sesquifolia, Clarke in Hook. Ic. Pl. xviii. 
t. 1797. 
SzECHUEN : mount Omei, at one place only (Faber!) Herb. 
Kew. 
This is almost exactly the counterpart of Chirita monophylla, 
Clarke, but it is placed in this genus because it has four appa- 
rently fertile stamens. As a matter of fact, the shorter pair have 
smaller anthers than the others, and in Chirita bifolia, D. Don, 
the lower pair are almost as fully developed. But as Mr. Clarke 
asserts (DC. Monogr. Phanerog. v. 1. p. 8) that the character of 
2 or 4 stamens is absolute for each species of Cyrtandres, we 
refrain from disturbing the limirs of the genera, especially as we 
have no better basis to suggest.
