VII. CONOPHARYNGIA, G. Don. 
(TABERNEMONTANA, Benth. et Hook. f. Gen. Pl. ii. 706 partly.) 
Calyx small (at least comparatively), subcoriaceous; sepals united 
at the base only, imbricate, obtuse, each with several minute glands 
inside the base. Corolla salver-shaped, small to large, often very 
fleshy ; tube cylindric, spindle- or barrel-shaped, widest at or below 
the middle, sometimes twisted, naked at the mouth, usually more or 
less tomentose inside ; lobes overlapping to the left, inflexed and 
descending into the corolla-tube in bud. Stamens in the widened 
part of the eorolla-tube ; anthers conniving into a cone, subsessile, 
included, rarely shortly exserted in species with a short corolla-tube, 
lanceolate, acute, sagittate ; tails solid, barren ; filaments reduced to 
a callous swelling; filamental ridge usually distinct. Dise 0. 
Carpels 2, free; style filiform to columnar, short (at least com- 
paratively); stigma cylindric, grooved, with an entire or lobed 
projecting rim or short frill at the base and a minute 2-lobed 
apiculus, more rarely (§ Leptopharyngia) elliptic or globose, delicately 
papillose, not grooved, with a usually toothed rim at the base and a 
conspicuous 2-fid papillose apiculus as long as or rather longer than 
the rest of the stigma. Mericarps baccate, usually more or less 
globose or ovoid, smooth, rarely keeled or warty and tardily 
dehiscent when drying up. Seeds numerous, embedded in a usually 
fleshy pulp, more or less ellipsoid, deeply grooved ventrally ; testa 
crustaceous; endosperm fleshy, ruminate; cotyledons ovate, longer 
_ or shorter than the radicle. 
Trees, often tall, or shrubs. Leaves opposite, more or less coriaceous, some- 
times very large ; axillary stipules distinct, very obtuse, united into a very short 
tubular sheath, usually with very numerous resiniferous glands within, In- 
florescences terminal or pseudo-axillary, corymbose, rarely panicled or reduced 
to few-flowered cymes. Flowers large and showy to middle-sized, rarely small, 
usually white and fragrant.
