14. Sarcopyramis Wallich, Tent. Fl. Napal. 32. 1824.

肉穗草属 rou sui cao shu

Herbs. Stems erect or creeping, 4-sided. Leaves petiolate; leaf blade papery to membranous, secondary veins 1 or 2 on each side of midvein, tertiary veins parallel, margin usually serrulate. Inflorescences terminal cymes, nearly capitate, 3-5-flowered, base 2-bracteate; bracts foliaceous. Pedicel short, 4-sided, usually narrowly winged. Hypanthium cupular to cupular-funnelform, 4-sided, usually winged on angles. Calyx lobes 4, apex usually truncate but tip armed pubescent or a fimbriate membranous disk. Petals 4, pink to purplish red, usually oblique, apex apiculate. Stamens 8, equal in size; anthers obcordate or obcordate-elliptic, dehiscience poricidal; connective base usually decurrent forming a curved spur or bulge. Ovary inferior, 4-celled, apex with a membranous crown. Capsule cup-shaped, 4-sided, 4-poricidal, crown usually exserted from hypanthium. Seeds small, numerous, long obovate, densely papillose tuberculate.

About two species: Bhutan, China, NE India, Indonesia, Malaysia, Myanmar, Nepal, Philippines, Thailand; two species (one endemic) in China.

The genus was revised by Hansen (Bot. Tidsskr. 73: 177-184. 1979), who recognized a single species, Sarcopyramis napalensis, without subordinate taxa. In China, however, tiny plants from several collection sites have traditionally been accepted as a separate species (S. bodinieri), and this practice is followed here. Field studies are required to resolve the status of S. napalensis and S. bodinieri.

1 Leaf blade ovate to elliptic, 1-5 × 0.7-5 cm.   1 S. bodinieri
+ Leaf blade broadly ovate, ovate, or rarely sublanceolate, (2-)5-10 × (1-)2.5-4.5 cm.   2 S. napalensis
