 The forms here included in this species differ from each other somewhat 

 in the size, acuteness and pubescence of the leaves. It is not improb- 

 able that some of them may be B. basalt's, Anderss., B. parvifolia, 

 Hook, f., or B. falcifolia, Hook. f. , nearly related species which, to 

 judge from the material at hand, do not appear likely to prove distinct 

 in nature. 



B. falcifolia, Hook. f. (3), 219; Anderss. (1), 193, & (2), 77. B. 

 lancifolia, Anderss. (1), 191, & (2), 76, evidently a typographical error 

 for falcifolia. — Albemarle Isl.: Macrae? ace. to Hook, f., I.e. 

 Endemic.

 pageia, Rob. & Greenm. (1), 141. — Duncan Isl.: Baur, no. 145 

 (hb. Gr.). Endemic. 



B. linearifolia, Hook. f. (3), 217 ; Anderss. (1), 191, & (2), 76.— 

 James Isl. : Darwin. Endemic. 



B. ovalts, Anderss. (1), 192, & (2), 76, t. 8, f. 3. Leaves 6 to 8 mm. 

 long, rounded at the apex. — Charles Isl. : in dry and grassy places 

 on the upper part of the island, Andersson (hb. Gr.). Endemic. 



Forma abingdonensis. B. ovalis, Rob. & Greenm. (1), 149, as to 

 pi. Abingdon. Foliis ad 1.5 era. longis plus minusve acutis. — Abing- 

 don Isl. : Baur, no. 142 (hb. Gr.). Endemic.

 Galapagos Ids. : Habel. Albemarle Isl. : Macrae. Endemic. A 

 pubescent form of B. ericaefolia?
