 erect, the other two as long but reflexed, oblong-ovate; lip about as long 

 as the corolla-lobes, spreading. Capsule ellipsoid, woody, 3 to 4 cm long, 

 splitting into 3 valves, crowned by the persistent calyx. (Fl. Filip. pi.

Waste places, Singalon, rare, fl. all the year; widely distributed in

7. COSTUS Linnaeus 



Tall leafy herbs, sometimes branched, the leaves oblong to lanceolate, 

 spirally arranged, the sheaths entirely closed. Inflorescence a dens«) cone- 

 like, terminal or basal spike, the bracts sti£f, imbricate, persistent. Calyx 

 tubular, 3-lobed. Corolla-tube broadly funnel-shaped, as long as the calyx- 

 tube, the lobes large, showy, oblong to lanceolate. Lip large, obovate, 

 somewhat spathe-like below. Stamen very broad and thin, petaloid, the 

 staniinodes none. Capsules woody, 3-celled, splitting down the back of each 

 cell; seeds very numerous, black, angled. (The ancient Greek name.) 



Species about 100, chiefly in South America and Africa, few in the Indo- 

 Malayan region, 2 in the Philippines. 



1. C. speciosus (Koenig) Smith. 



Stems stout, about 1 m high and 1.5 cm in diameter, leafy. Leaves 

 spirally arranged, oblong, acuminate, subsessile, about 30 cm long, softly 

 pubescent on the lower surface. Spikes solitary, terminal, ovoid, very 

 dense, 5 to 8 cm long, the brac1;s ovate, acuminate,, purple, 3 to 4.5 cm long. 

 Calyx flattened, purple, about 3 cm long, the lobes 3, rather short, ovate. 

 Corolla-segments white, oblong, 5 to 6 cm long, pointed. Lip white, sub- 

 orbicular, 6 to 8 cm long, crinkled, irregularly and rather finely toothed, 

 the margins incurved and meeting. Stamen flat, including the broad con- 

 nective about 5 cm long, 12 to 15 mm wide. Capsules ovoid to globose, 

 red, crowned by the persistent calyx, 1.5 to 2 cm long. (Fl. Filip. pi. UZ.) 



Occasionally cultivated, fl. Sept.-Dec; widely distributed in the Phil- 

 ippines. India to Formosa, southward to New Guinea. 



30. CANNACEAE (Canna or Ticas-ticas Family) 



Erect, coarse, perennial, unbranched herbs with leafy stems irom fleshy 

 rootstocks. Leaves large, oblong, acute or acuminate, parallel-veined from 

 the midrib, their petioles sheathing the stem. Flowers irregular, perfect, 

 medium to large, usually bright-colored and showy, in lax, simple or 

 branched, terminal racemes, bracteate. Sepals 3, small, oblong. Corolla- 

 tube cylindric, the segments 3, lanceolate, equal. Staminal-tube connate 

 below with the corolla-tube, the segments 4 or 5, unequal, petioled, touch 

 larger than the petals, one of the smaller ones with a single, 1-celled^ 

 anther attached to its margin. Ovary inferior, 3-celled; ovules many;^
