connate with the style into a column. Ovary inferior, 2-celled; stigma at 

 the apex of the column; ovules many. Fruit a 1- or 2-celled, 2-valved 

 capsule, the valves cohering at the base and apex, or only at the base. 



Genera 6, species about 130, mostly in Australia, few in Antartic America, 

 still fewer in India and Malaya, 1 1n the Philippines. 



STYLIDIUM Swartz 



Small, slender, glabrous, annual herbs. Flowprs axillary, sessile. Calyx 

 5-lobed, the lobes usually more or less united in two lips. Corolla irregular, 

 B-lobed, 4 lobes suberect in 2 pairs, and one smaller, recurved. Staminal 

 column elongated, apex at first deflexed, elastically reflexed when irritated. 

 Capsules small, elongated. (From the Greek "column," in allusion to the 

 connate style and stamens.) 



Species 103, nearly all Australian, 1 extending to the Philippines, 3 in 

 India and China. 



1. S. alslnoides R. Br. 



Slender, glabrous, erect or spreading, simple or irregularly branched, 

 & to 15 cm high. Leaves sessile, ovate, opposite, or the lower ones alternate, 

 acute or acuminate, 3 to 6 mm long. Flowers solitary, alternating, 1 at 

 each node in the axil of an often reduced leaf. Calyx-tube long, slender. 

 Corolla-lobes slightly exceeding the calyx-lobes, apparently pink. Capsule 

 riender, 1 to 1.5 cm long. 



In open, wet, grasslands, rice paddies, etc., San Lazaro, fl. in the rainy 

 reason; of local occurrence in the Philippines. Northern Australia and 

 Queensland. 



136. COMPOSITAE "■ (COMPOSITE OR SAMBONG FAMILY) 



Erect or spreading herbs, herbaceous or woody vines, shrubs, or very 

 rarely trees. Leaves alternate, rarely opposite or whorled, simple, entire, 

 toothed, or variously lobed, or compound. Flowers few to very numerous 

 in close heads which are solitary, or in racemes or panicles, each head 

 with an involucre of bracts surrounding the flowers, the receptacle pitted 

 or nearly smooth, naked or paleate. Calyx-tube united with the 1-celled 

 ovary, the the limb none, or of hairs (pappus), scales, or bristles, crowning 

 the summit and usually persistent in fruit. Corolla strap-shaped or tu- 

 bular, 3- to 5-toothed or lobed.. Stamens 4 or 5, inserted pn the corolla- 

 tube, their anthers united. Ovary 1-celled, 1-ovuled; style 2-cleft or entire. 

 Fruit a dry, indehiscent achene, usually cro'\vned by hairs, bristles, or scales. 



The largest family of flowering plants, comprising about 900 genera, 

 and over 14,000 species, in all parts of the world, but chiefly in temperate 

 regions, 51 genera and about 110 species in the Philippines. 



The flowers may be perfect or polygamous, monoecious, or dioecious. 

 Flowers with a strap-shaped (ligulate) corolla are called ray-flowers, and 

 these may be confined to the outer one or several rows, or all the flowers 

 may be ligulate; a head containing in part or all ray-flowers is called 

 radiate. The tubular or campanulate flowers compose the disk, and a head 

 that contains no ray-flowers is called discoid. When a head contains two
