222 DR. J. D. HOOKER ON THE PLANTS 
Exemplar solitarium. Caulis robustus, per totam longitudinem foliosus. 
Folia 5-6, 3-4 unc. longa, 2-3 lata, membranacea, non petiolata. 
Racemus post anthesin fere pedalis, floribus imbricatis. Bractee 
subulato-lanceolate. Ovarium apice contractum. Perianthium 5 
unc. latum. Labellum late oblongum, lobis brevibus obtusiusculis.

140. 
Hab. Fernando Po, alt. 10,000 feet. (Fl. Dec.) 
Also a native of Bourbon, if the same ; but the Fernando Po 
plant has the spur much longer than the ovary and not at all 
clavate. l 
23. HABENARIA Mannu, H. f., n. sp. Glaberrima, spithamæa, caule 
folioso basi vaginato, foliis lineari-lanceolatis acuminatis recurvis, 
bracteis late ovatis acuminatis ovario longioribus, floribus paucis am- 
plis, sepalis falcato-ovatis acuminatis, petalis linearibus obtusis, labello 
angusto 3-partito, calcari zequilonge, lobis anguste linearibus, exte- 
rioribus multifidis, columna brevissima 2-cruri, antheris distantibus 
eruribus insertis. 
Hab. Cameroons Mountains, alt. 7000 feet. (FI. Nov.) 
Caulis erectus, strictus, foliosus. Folia complicata, 3-nervia, 3-5-polli- 
caria, in bracteas floriferas abeuntia. Bractee concave, 2 unc. longe. 
Flores 1 unc. lati. Sepala 3-nervia, subcoriacea, patentia. La- 
belli lobi angustissimi. |Calcar incurvum, $ unc. longum, sensim 
inflatum, obtusum. Columna (valde singularis) brevissima, in ramos 
2 divaricatos et porrectos fissa, ramis cum processibus column: apice 
oblique truncatæ continuis. Anthere loculi longe distantes, caudiculis 
erectis. 
A most remarkable plant, very closely allied to three Abyssinian 
species, H. Quartiniana, macrantha, and decorata, in all of which 
the column is split to the base into two projecting arms, and the 
anther-lobes placed wide apart, one on each arm, with their cau- 
dicles turned up at right angles. 
49. InrDExX. 
l. TRICHONEMA BuLBOCODIUM, Ker.

A small-flowered form, in no way differing from the Abyssinian. 
The species is found from the Channel Islands to the Canaries and 
Azores, and throughout the Mediterranean region, Algeria, Asia 
Minor, Syria, and at Socotra in the Red Sea.
