Oct. 1897 (type). 
As the type of Léveillé’s species I have taken the first specimen 
quoted in the original description. If we take the character of 
the pilosity of the lower part of the style where the hairs are very 
long, white, and spread at right angles to the style, then Cavalerie, 
1898, from Tien-sen-kiao would also belong to P. C avaleriet. 
Cavalerie, 837, however, from Long-ly does not show this 
character, and again the filaments are not glabrous. This 
collection I should refer to P. Martini.
