A very distinct species; agreeing with Strobiiina in having the corolla tube hirsute within, but 

 differing from these in general habit as to which it agrees with the rest of the genus. It most closely 

 resembles G. nheum in foliage and tomentum, hut its included, distinctly incurved, and internally hirsute 

 corolla, its much larger calyx which has longer teeth, and its grey (in place of white) tomentum, amply 



distinguish it. The species is dedicated to Mr. W. B. Hemsley, hut for whose kind assistance it would have 

 been impossible for me to have prepared this account of the genus. ' 



If Gomphostemma flavescem Miq., Flor. Ind. Bat. ii, 987 [1856] {Anthocoma flavescem Zoll., Nat. 

 en Geneesk. Arch, ii, 569 [1846] ) is truly referable to this genus, it must stand next to G. Hemsleyanum. 

 The hirsute nutlets, however, indicate a hirsute ovary, and imply a relationship with Lucida, similar to that 

 indicated by Eriocarpon among the Stenostomata. It would therefore be necessary to give it the rank 

 of a group which might he denned as follows : 



116. Anthocoma ; verticillastris remotis axillaribus, calyce intus glabro, ovario hirsuto, nuculis oblongis. 



But in the absence of authentic specimens it is impossible to localise this species definitely, and in 

 view of the doubts as to the generic position of the plant (already fully discussed, p. 231, footnote) this 

 must be looked on as a purely tentative definition.
