SECTION I: G. ROBINSONI 67 



yellow, wide convolvulate, not having purple claws; calyx cut almost 

 square across or with 5 shallow undulations. Fruit and seed not seen by 

 me, and not described by the original author nor by subsequent writers. 



Habitat. Found on stony places in the lower sterile regions of Gala- 

 the Islands of Chatham and Charles, Galapagos. 



Citation of Specimens. Andersson's n. 173, seen both in Kew and Speci- 

 Geneva Herbaria ; also Captain Wood's specimen. mens. 



The plant was named in honour of Dr. Fr. Klotzsch, of whom Andersson 

 speaks in high praise for his knowledge of the flora of these islands. 



Nomenclature. A specimen which, through the kindness of 

 M. Casimir de Candolle of Geneva, I have had the pleasure to 

 inspect, bears on the attached label (in Andersson's handwriting 

 apparently) the name ' G. ptirpurascens, Poir., var. Klotzschianum' 



I am, however, by no means satisfied that all the specimens 

 that have been attributed to G. Klotzschianum in reality belong to 

 it. With better material it seems possible there may be at least 

 two additional species. I propose, accordingly, to establish one 

 G. Darwinii but the present plant is, as already pointed out, closely 

 allied to a Gossypium found in California, which may prove a third 

 member of the assemblage. The plants indicated, however, would 

 hardly differ more from each other than might be expected, from the 

 antiquity of the separation of the islands from the mainland, and Ancient 

 would be but another example of a condition pointed out by Hooker islands, 

 and other writers on the plants and animals of the Galapagos (cf. 

 ' Island Life,' A. E. Wallace, 1892, 287-91).

 minute, caducous. Inflorescence on special flowering shoots, 2J to 3 inches 

 long, terminated by two or three leaves and one or at most two flowers ; 

 bracteoles ovate oblong acute, entire, tapering below, and quite free from
