CANAVALIA MEGALANTHA sp. nov. 
Species C. turgidae Grah. simillima et ut videtur affinis, differt 
caulibus distincte lignosis, circiter 1 cm diametro, floribus ma- 
joribus, 4 ad 4.5 cm longis. 
A woody vine, entirely glabrous, the stems terete, firm, 7 
to 10 mm in diameter, brownish, lenticellate. Leaflets mem- 
branaceous, the terminal one broadly ovate, about 12 cm long, 
10 cm wide, acuminate, base rounded, the lateral leaflets similar 
but strongly inequilateral, broader on one side of the midrib 
than on the other. Flowers rose-pink, racemose, the racemes 
solitary, 10 em long or more, axillary and from the woody 
stems, comparatively few-flowered, flower-bearing nearly or quite 
to the base, the nodes swollen, the pedicels 5 mm long or less. 
Calyx 1.5 cm long, the upper lip considerably longer than the 
lower one, retuse or cleft into two broadly rounded lobes 5 to 
8 mm wide, the lower lip with three, oblong-ovate, acuminate 
teeth about 3 mm long. Corolla rose-pink. Standard 4 to 4.5 
em long, the limb obovate, about 2 cm wide, prominently retuse; 
wings as long as the keel, 5 to 7 mm wide, rounded; keel curved, 
the petals up to 9 mm wide. Stamens all perfect. Fruit un- 
known. 
R. C. McGregor 552, in forests, Upi road, October, 1911. 
Manifestly a representative of the genus Canavalia, and in vegetative 
characters quite like Canavalia. turgida Grah. It is distinguished by its 
woody stems, its short racemes which are flower-bearing to the base, and 
especially by its unusually large flowers.
