praecipué pubescenti-velutinis, floribus in corymbis compositis lateralibus 
terminalibusve dispositis, pedunculis elongatis, pedicellis brevibus, peri- 
anthio campanulato, staminibus exsertis.

Rami lignosi, cortice cinereo. Folia 2-3-pollicaria, petiolis 1 uncialibus. Corymbi pubes- 
centes, pedunculis petiolo zquilongis. Antherz majusculz. 
A large tree, growing between the low dry and upland moist countries, 
almost leafless. The specimen is very defective, and allied to a species of 
Bertero from the Pacific, as also to a South Brazilian Species gathered by 
Tweedie. ; 
PLUMBAGINEE. 
104. PLUMBAGO SCANDENS, L. 
Hab. Albemarle and Charles Islands, Charles Darwin, Esq. A very common tropical 
plant. 
105. P. romentosa, Lam.? 
Far. pumila; acaulis, annua, foliis stellatim patentibus obovato-lanceolatis 
sinuato-dentatis i—$ unc. longis parcé pilosis, pedunculo abbreviato- 
hirsuto, spicá brevi 6-8-florà, capsulis latis dispermis.

These specimens are in a young ora starved state. I suppose them to belong 
to a large and common Chilian and Buenos Ayrean plant named P. tomentosa, 
Lam. (in Hort. Reg. Berol.). The roots of the latter are often perennial, the 
leaves 2-4 inches long, and, together with the peduncles, more or less hispid. 
The spikes vary considerably in length, from 2-3 inches. After flowering, the 
segments of the corolla imbricate over the ripening capsule and form a conical 
hood to that organ. In many respects this resembles the P. y irginica, L., 
where however the peduncles are generally long and slender, and the leaves 
erect and long. 
VERBENACEZ. 
106. VERBENA OFFICINALIS, L. 
Hab. James Island, Charles Darwin, Esq. 
This appears to be a very widely diffused species, and the two following 
are certainly closely allied to it.
