 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. basalts, Anderss., B. parvifoUa, 

 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. 

 lancifoli a, 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. ovALis, 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 cm. longis plus minusve acutis. — Abing- 

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

. B. parvifolia, Hook. f. (3), 218; Anderss. (1), 193, & (2), 77.— 

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