7. G. (Mert.) longissima, Bl. ; large, often many ft. long ; st. stout, forked ; 

 branches very long, bearing numerous close-placed pinnce 4-6-8 in. 1., 1-2 in. br., 

 deeply pinnatifid to the rachis ; the segm. linear, acuminated, or oblong, paler or 

 more or le&s glaucous beneath, glabrous, or (especially when found at great eleva- 

 tions) densely ferrugineo-tomentose, and very paleaceous on the St. rachis and 

 young shoots ; caps. 3-5, often mixed with hairs. — Hk. Sp. 1. p. 4. G. glauca,

 — /3, Borneo, elev. 7,000 ft.. Low. Java, Bhme, De Vriese. — My copious specimens from 

 the above -Jooalities quite satisfy me that the supposed species enumerated are trifling 

 modifications of one and the same ; glauca is the oldest specific name. 



** Kr. dichotomous {redely simple); pinnatifid; in other words, the leafy or 

 frondose portion is not confined to the forked apices, but is dectirrent upon t/te 

 branched portion of the st. Sp. 8-21. 



8. G. (Mert.) flabellata, Br. ; fr. very proliferous ; branches dichotomously 

 flabelliform, submembranaceous ; pinnce ascending, a span and more 1., 1-2 in.

 caps. 3-5, inserted, sessile," Br.— Hk. Sp. l.p. 6. ' 



Hab. Tasmania. — What I suppose to be this, is probably a small and young form of O.fla- 

 bellala with shorter and more spreading segm., and is slightly and partially villous and scaly.
