6 DR. HOOKER ON THE VEGETATION 
CARYOPHYLLEX. 
l. Sagina Abyssinica, Hochst. ; Rich. Fl. Abyss. i. 47. 
Hab. In Clarence Peak, alt.? (fl. Dec.) 
This is absolutely identical with the Abyssinian plant, and is a very 
distinct species from any other. The flowers are often tetramerous. The 
only other Fernando Po plant of this order is Drymaria cordata, W., which 
grows at low levels. 
HYPERICINEE. 
1. Hypericum angustifolium, Lamk. ; DC. Prodr. i. 545. 
H. leucoptychodes, Steud. ; Rich. Fl. Abyss. i. 96. 
Hab. In Clarence Peak, 7-10,000 ped. copiosissime. (fl. Dec.) 
Arbuscula 30-pedalis. Folia interdum et sepala secus marginem punctata, 
sæpius omnia impunctata. 
The Bourbon specimens of this noble plant have the leaves rather nar- 
rower than the Abyssinian, and wholly impunctate. In both the Fernando 
Po and Abyssinian specimens, the calyx and leaves have sometimes the 
margins punctate. The leaves of the Fernando plant are in some specimens 
like the Abyssinian, in others like the Bourbon. It is a very common tree 
in the mountains of Abyssinia. 
GERANIACEJE. 
l. Geranium Simense, Hochst.; Rich. Fl. Abyss. 1. 116. 
G. Emirnense, Hils. & Bojer, MSS. in Hb. Hook. 
Hab. In Clarence Peak, alt. 8500 ped. (fl. Ap.-Dec.) 
Mr. Mann's specimens are identical with Bojer's Madagascar G. Emir- 
nense, and with some of Schimper’s Abyssinian G. Simense, which A. 
Richard describes as a very variable plant, and common in the cold regions 
of Abyssinia. : 
BALSAMINEJ. 
This order is probably common in the hilly regions of Tropical Africa, 
whence I have seen about a dozen species. Only one, however, is described 
as Abyssinian, and one South African. I shall here describe four Fer- 
nando Po species, of which only one ascends to 5000 feet, and none have 
been found above that elevation. I have referred these to the sections 
adopted in the monograph of the East Indian species, published in the 
fourth volume of this Journal. They are as follows :— 
1. UxunELLAT. Folia alterna. Flores ad apicem pedunculi elongati 
congesti v. dense racemosi. 
2. UNIFLORÆ. Folia alterna. Pedicelli in axillis foliorum solitarii v. 
fasciculati, uniflori. 
3. LaTERIFLOR&. Folia alterna. Flores racemosi, racemi foliis bre- 
viores v. axillis foliorum inferiorum dispositi.
