440 A FLORA OF MANILA 



nearly white outside, the upper surface of the lobes pale-blue-purple, the 

 tube constricted above the ovary, then expanded, the limb 8 cm broad, 

 spreading. Filaments widened below; anthers bearded. (Fl. Filip. pi. 

 2S9.) 



Commonly cultivated in Manila and in many of the larger towns of the 

 Archipelago, fl. throughout the year, but apparently producing no seeds in 

 our area. A native of India, now cultivated in many tropical and subtrop- 

 ical countries. 



2. T. AiiATA Bbjer. 



A slender, herbaceous vine, more or less pubescent. Leaves ovate-cordate, 

 acute, 4 to 10 cm long, the petioles prominently winged, 1 to 7 cm long. 

 Flowers axillary, solitary, peduncled, the bracteoles ovate, green, 2 cm long, 

 somewhat keeled in the lower one-half. Corolla pale-yellow with a whitish 

 center, or darker-yellow and with a dark-purple center, the limb 3 to 4 cm 

 in diameter. Capsule depressed-globose, about 8 mm thick, the beak stout, 

 about 1 cm long. 



In thickets, occasional, fl. Oct.-Dec.; local in Luzon, and of recent intro- 

 duction, but thoroughly naturalized. A native of Africa, now found in 

 India and Malaya. 



3. T. fragrans Roxb. 



A slender, glabrous or nearly glabrous, herbaceous vine reaching a height 

 of 2 to 3 m or more. Leaves 5 to 10 cm long; oblong-ovate to oblong-lanceO' 

 late, acuminate, base rounded,, cordate, or hastate, sometimes toothed, the 

 basal lobes if any, acute. Flowers axillary, solitary, pedicelled. Bracteoles 

 green 1.6 to 2 cm long. Calyx short, toothed. Corolla white, 3 to 4 cm long, 

 the tube slender. Capsule 2 to 2.5 cm long, glabrous, shining. 



In thickets Pasay, fl. most of the year; widely distributed in the Philip- 

 pines. India to northern Australia. 



*4. T. EJRECTA (Benth.) And. 



An erect, branched, glabrous shrub 1 to 2 m high, with slender, 4-angled 

 stems. Leaves ovate to elliptic-ovate, 1 to 3.5 cm long, entire or slightly 

 angular-lobed, acute or acuminate. Flowers axillary, solitary, the bracts

 stricted below, inflated and -about 1 cm in diameter above_, the lobes spread- 

 ing, white or deep violet-purple, the limb 3 to 4 cm in diameter. 



Somewhat cultivated, fl. all the year. A native of tropical Africa, of 

 very recent introduction in the Philippines. 



10. STAUROGYNE Wallich 



Erect herbs with opposite leaves which are entire or nearly so. Inflores-

 like, or small and inconspicuous, the bracteoles 2 near the base of the calyx, 

 smaller than the bracts. Sepals 5, oblong to linear, one larger than the 

 other, or subequal. Corolla-tube cylindric, the lobes 6, spreading, short. 

 Stamens 4, in 2 pairs, the filaments hairy; anther-cells spreading. Ovules 

 very many. Capsule oblong, not stalked, bearing seeds from the base to the 

 apex. Seeds numerous in each cell, seated on minute papillae. (Greek 

 "cross" and "woman" in reference to the bifid plates on the stigmas of some 

 species.) 



Species 45 or 50 in tropical Asia, Malaya, Australia, and Brazil, 2 or 3
