This also is a dwarfish species, which attaches itself to the sur- 
face of rocks, like the preceding species ; but it appears to be 
somewhat more erect, with stouter and straighter branches, 
which are closely beset with very short branchlets, all covered 
with shorter, more numerous, and more minute leaves. In the 
specimen above cited, the flowers are only in bud, and few are 
developed ; these, however, are sufficient to show their structure. 
The leaves, with their petioles, scarcely exceed 1| line, or at 
most 2 lines in length, and 1 hne in breadth. The flowers are 
smaller than in the preceding species. It has much the habit 
of the Rhamnus microphyllus of Kunth (tab. 616), but with still 
smaller leaves*. 
4. Ochetophila riparia, Popp. MSS. 
5. Ochetophila diver gens, Popp. 
No description has yet been given of these two species, their 
existence only being indicated in Endlicher’s ' Genera Plantarum^ 
(No. 5733), where they are stated to have been found by Poppig 
in Chile. 
5. Adolphia. 
This must be considered in some degree as an aberrant genus 
of the Colletiece, amongst which it has been placed by Endlicher. 
IMy reason for this doubt is founded on the structure of its 
calyx, which is cleft down to the limit of the adnate disk, the 
consequence of which is that the stamens appear to originate 
outside the margin of the disk, as in the Rhamnece, thus divest- 
ing it of one of the pecuhar and distinctive characters of the 
Colletiece ; on the other hand, the species on which the genus is 
established has opposite leaves, — a feature rarely or imperfectly 
developed in the Rhamnece. I have also noticed, in the structure 
and mode of dehiscence of the anthers, another character found 
in some of the genera that follow, which I do not see recorded 
of any species of the Rhamnece. Dr. Asa Gray remarks (PI. 
Wright, p. 34) that Adolphia hardly differs from Colubrina, 
which may be true in some degree, as far as regards the struc- 
ture of the flower ; but that genus has alternate leaves. Ceano- 
thus is in the same category, although its fruit, as in Colubrina,
