11. CRYPTOSTEGIA R. Brown. 
Climbing woody vines with opposite shining leaves. Flowers large, 
showy, in few-flowered, terminal, dichotomous or trichotomous cymes. Se- 
pals lanceolate. Corolla funnel-shaped, the tube short, the limb campanu- 
late, with 5 broad lobes. Coronal-scales at the base of the throat, subulate, 
entire or 2-cleft. Filaments short; anthers adnate to the stigma, acute; 
pollen-masses in pairs in each cell. Follicles thick, divaricate, hard, 3- 
winged, furrowed between the wings. Seeds comose. (Greek “conceal” 
and “cover.”’) 
Species 2, tropical Asia and Africa, 1 introduced in the Philippines. 
* 1. C. GRANDIFLORA (Roxb.) R. Br. 
A stout woody vine, glabrous or nearly so. Leaves oblong-ovate to 
elliptic-ovate, acuminate, 6 to 10 cm long, base rounded. Cymes short. 
Sepals green, about 8 mm long. Corolla pale-purple, about 4 cm long, often 
wider than long. Follicles 10 to 12 em long, woody. 
Occasionally cultivated, fl. Aug.Sept., and probably in other months, of 
recent introduction here. Supposed to be a native of Madagascar or tropical 
Africa, cultivated in India and in many other tropical countries. 
2. STREPTOCAULON Wight & Arnott 
Twining, pubescent, somewhat woody vines, usually slender. Leaves 
opposite. Flowers small, numerous, in axillary, lax, panicled cymes. Calyx 
small, 5-partite, with 5 scales within at the base. Corolla rotate, the tube 
very short, the lobes ovate, slightly imbricate. Corona-processes filiform, 
adnate to the backs of the filaments. Stamens inserted at the base of 
the corolla, alternating with minute glands; anthers oblong, adherent to 
the style-apex; appendages small, triangular, connate over the apex of the 
style; pollen-masses 2 in each cell. Ovary of 2 distinct carpels; style short. 
Follicles in pairs, divaricate, slender, pubescent. Seeds flattened, keeled on 
the lower surface; coma white, silky. (Greek “to twist” and “stem.”) 
Species about 7, India to Malaya, 2 in the Philippines.
