Mr. J. Miers on the Tribe Colletiex. ll 
2-loculari—Ins. Gallapagos.—». s. in herb. Hook. ; Albemarle 
Island (Darwin). - 
This plant appears to correspond well in its characters with 
the preceding and the following species: it grows abundantly, 
forming thickets near the sea. Its branchlets are slender and 
very glabrous; the spines are from 12 to 20 lines long, and the 
internodes 4 lines apart ; the leaves are nearly 1 inch long, and 
4 lines broad, on a petiole 1 line in length. It is worthy of 
remark, as indicative of the limit of the genus, that many of the 
plants of the Gallapagos are identical with those of Guayaquil, 
which is in the same latitude, and the nearest opposite point 
of the continental coast *.

There is a great approximation of characters between this and 
the two former species, and more especially with the last, the 
principal difference consisting in its ovary, which is represented 
as being 3-locular,—a difference which it must be remembered 
exists also in Jrevoa. Contumasai, where it is found, is scarcely 
4° south of Guayaquil. Its branchlets are glaucous, and obso- 
letely pubescent, as well as sub-4-gonous; its spines are hori- 
zontal and opposite, sometimes a little alternate, and from 10 to 
20 lines long; its leaves are said to be not quite an inch long, 
on a petiole 1 line in length, but they are now wanting in the 
specimen. Kunth observes that the leaves are very deciduous, 
and that the specimen he examined was almost aphyllous, look- 
ing quite like a Colletia ; the same may be said of S. pauciflora, 
The floriferous branchlets are about the length of the spines, 
spring from below them, and are more slender and flexible: the 
flowers (1 or 2) are sessile in the opposite axils of the nodes,
