L'lilliiiidia valjjviiHi is a very distinct species and is easily recognized, even if 

 ncit in a flowering stage, by the papillose hispid leaves. 



The species was collected by Gaiidicliand in young fruit: it was never pub- 

 lished by him, but liears the name UoUandki ferrughua ospern, with a question 

 mai-k after Rnllandia. 



Wawra's specimen (h'oUaiulia scabra) belongs to RnUaiidid cahiciiid and imt 

 to li'dllnitdia laiiccolata as reported by llillebrand. 



The writer's materia! varies slightly from the original description; the leaves 

 are longer and less suddenly contracting at the base, the i)eduncles are also 

 longer; otherwise the same. 



According to Hillebi'and, Jleyen's specimen labeled "//. crhpa" belongs to 

 B. cahjcina.

 Strm 1 m to 2 m tall, leaves chartaeeous, obovate oblong, 26-40 cm long, 8-15

h'dlldiidia Iliniibdld'idita figured In' Caudichaud in his Atlas of the Botany 

 Voyage Bonite represents a plant in the flowering stage, but with flowerbuds only. 

 Everyone who has worked on Hawaiian Lobelioideae knows that a raceme keeps 

 on growing till practically the la.st fruit has matured. This accounts for the 

 variable length of the racemes (8-40 cm). Hillebrand was well aware of the 

 facts above mentioned, but could not have been very well ac([uainted with (iaudi- 

 chaud's plate of R. H iiinbnldtiaiia or else he would have placed Mann's Dclissca 

 racemosa as a synonym of Ii. II iniiJidldliaua. This latter species has very short 

 petioled leaves, and as can be seen in the excellent plate, the upper anthei's are 

 naked; this is also the ease with the plants referred by both JIann and Ilille-
