432 A FLORA OP MANILA 



1. RHYNCHOGLOSSUM Blume 



Succulent herbs, slightly pubescent or nearly glabrous. Leaves alternate, 

 obliquely elliptic, thin, base very unequal-sided, one side broadly rounded 

 or cordate, the other acute, entire or slightly sinuate. Racemes elongated, 

 slender, many-flowered. Calyx ovoi3 or campanulate, 5-Iobed. Corolla 

 bine, the tube cylindric, contracted at the mouth, the limb 2-lipped, the 

 upper lip short, bifid, the lovsrer' longer, 3-lobed. Stamens 2, perfect, in- 

 cluded; anthers connivent. Ovary ovoid. Capsule included in the calyx, 

 ellipsoid, membranaceous, loculicidally 2-valv6d; seeds sn^all, numerous. 

 (Greek "beak" and "throat," from the small upper lip of the corolla.) 



Species 3 or 4, India to Malaya, 2 or 3 in the Philippines. 



1. R. obliquum Blume. 



An erect, branched, annual, slightly pubescent or nearly glabrous, 

 succulent herb 10 to 60 cm high. Leaves membranaceous, 4 to 15 cm long, 

 entire, acute or acuminate, the round side of the base extending much 

 farther along the petiole than the acute side. Racemes slender, erect, 5 

 to 15 long. Flowers few to many, rather distant. Calyx green, about 

 5 mm long. Corolla blue, the tube slightly incurved, about 1 cm long. 



Oh wet cliffs opposite Fort McKinley, rare, fl. Sept.-Dec; widely dis- 

 tsibuted in the Philippines in damp ravines, etc. Malaya, a variety in 

 India. 



128. LENTIBULARIACEAE (Bladderwort Family) 



Annual, terrestrial or aquatic herbs, the leaves whorled, persistent, 

 pinnately compound, divided into numerous filiform segments, the segments 

 usually bearing small bladders at their bases, or in the terrestrial species 

 alternate and disappearing before flowering. Scapes erect, the flowers 

 racemosely arranged, yellow, purplish, or nearly white. Flowers perfect, 

 irregular, few. Calyx divided into 2 distinct or nearly distinct sepals, often 

 enlarged in fruit. Corolla 2-lipped, base spurred, the upper lip entire or 

 2-lobed, the lower larger, often 3- to 5-lobed. Stameift 2, inserted on the 

 base of the corolla. Ovary superior, 1-celled, many-ovuled. Fruit a small 

 2- or 4-valved capsule. 



Genera 5, species about 250, in all parts of the world, a single genus 

 with about 10 species in the Philippines.
