634 Flora of the Malayan Penins^da. 



3. Staueogyne, "Wall. 

 Undershrubs, 6 to 24 in. (rarely 3 to 4 ft.) high, at base often 

 woody, creeping, hairy (in S. subglabra nearly glabrous). Leaves 

 opposite, equal, simple, entire ; petioles usually long, rarely short, -25 to 

 •5 in. Floioers in spikes (or spike-like racemes, the pedicels up to 

 •15 in.), dense or lax ; the spikes sometimes panicled. Bract usually a 

 little longer than the calyx, sometimes considerably broader ; two pro- 

 phylla (often alternate), linear or nearly linear, a little shorter than the 

 bract. Calyx -15 to -6 in. long, divided nearly to the base into 5 narrow 

 persistent segments (often called sepals) ; of these one is often longer 

 and sometimes much broader than the others. Corolla '5 to 1 in. long, 

 tubular- campanulate, rather narrow ; limb of 5 short rounded segments 

 (often colorate). Stamens 4 didynamous, fertile; filaments sparsely 

 hairy, and with gland-tipped hairs near the top ; anthers of 2 ellipsoid 

 cells, ultimately divaricate ; pollen globose, with three longitudinal 

 bands not reaching the poles, 25 to 30 /x in diam. Ovary oblong, 

 surrounded at base by a disk, glabrous or rarely with minute scattered 

 hairs ; style long, sometimes with a few hairs in the lower part ; 

 branches 2, unequal. Capsule oblong, -2 to -25 in. long, ovoid at base, 

 acute at top, glabrous or sometimes slightly minutely hairy, 2-celled, 

 separating loculicidally into 2 valves, bearing seeds from the base ; 

 seeds 12 to 20 in each capsule, in vertical rows on the edges of the 

 carpeUary leaves. Seeds attached on very small papillae, not on 

 retinacula, short-ellipsoid, 400 /x long, yellow-brown ultimately black, 

 smooth, more or less reticulate, minutely pitted. — Disteib. Species 40 

 in South-East Asia, 10 in Brazil. 



Some of the Brazil species have flowers and capsules considerably larger than in 

 the Asiatic species. The Asiatic species are so uniform in the corolla, stamens, and 

 pistil — even down to the hairs thereon — that these are not described for the subjoined 

 Malay species, which are separated mainly by characters of the bracts and calyx. — 

 The posticous stigmatic lobe (both in the type species iS. argentea, and in some 

 others) is occasionally somewhat 2-lobed.
