EUGOMPHOSTE 1IMA. 



Plate 94. Gomphostemma lucidum Wall, Specimen of var. typica from Khasia, 



Gallatly n. 243. 



This species is nearly related to G. oblongum, and may usually be distinguished by its serrate (not 

 crenate) leaves which are narrower and smaller, as well as by its distinctly smaller flowers, the tomentum 

 on which is generally rufous, and is always much denser than on those of G. oblongum. But the leaf 

 character fails, since Andamans gatherings of G. oblongum shew crenate and serrate leaves on the same 

 branch. Mr. Bentham has used as diagnostic the character " calycibus . . . dentibus .... abbreviatis " 

 for G. lucidum, and "dentibus lanceolato-Knearibus acutis" for G. oblongum — an expression which makes 

 his description of G. lucidum refer exclusively to Wallich's Sil/iet plant, and which excludes Wallich's 

 'fcnasserim one. There is no specimen of Wall. Cat. n. 2156/1 at Calcutta, hut Mr. Hemsley has 

 very kindly compared for me at the Linnean Society's rooms a specimen from Amherst {Falconer n. 

 1033) which agrees with it exactly, and Falconer n. 1033 in turn is precisely the same as a plant 

 3m the herbarium of the late Mr. Kurz) cultivated in the Buitenzorg garden. This plant is more 



mi 



nearly related to G. javanicum, with which it agrees (at the same time differing from G. lucidum) in 

 having a glabrous style and in having a calyx with long teeth and distinct pedicels. But though 

 from these specimens it is evident that Wall. Cat. n. 2156/1 is specifically distinct from Cat. n. 2156/2, 

 I have refrained from restricting the name G. lucidum to Wallich's n. 2156/1. For Falconer n. 1033 

 and Kurt n. 1154 differ from true G. javanicum mainly in being densely tomentose, and 

 well be treated as a variety of that plant. But were this reduction made it would be necessary 

 to submerge 6. javanicum (1835) in G. lucidum (1828)— a course that would be highly inexpedient; 

 for while it is true that G. lucidum (1828) did include Wall. Cat. n. 2156/1, it is equally true 

 that G. lucidum (1831) as described in Wall. PL As. Rar. and in all subsequent works refers precisely to 

 n. 215G/2 and explicitly excludes n. 2156/1 by the character "dentes calyeini vix lineam longi." In 

 the present paper therefore a figure has been given of, and the name G. lucidum is hereby expressly 

 limited to, the plant which forms Wall. Cat. n. 2156/2. 



As in the case of G. Heyneanum, the two varieties are very distinct, and yet there is no character 

 of calyx or corolla wherein they differ.
