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 ovoid or campanulate, 5-lobed. Corolla 
blue, the tube cylindric, contracted at the mouth, the limb 2-lipped, the 
upper lip short, bifid, the lower longer, 3-lobed. Stamens 2, perfect, in- 
cluded; anthers connivent. Ovary ovoid. Capsule included in the calyx, 
ellipsoid, membranaceous, loculicidally 2-valved; seeds small, 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. 
On wet cliffs opposite Fort McKinley, rare, fi. Sept._Dec.; widely dis- 
tributed 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. Stamens 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.
