472 A FLORA OF MANILA 



white hairs, hase long-narrowed, apex prominently 3- to 5-toothed or -lobed, 

 the lobes ovate to narrowly oblong. Heads in the upper axils, pedunded, 

 forming terminal leafy racemes, subglobose, 4 to 5 mm in diameter. 



A species of Chinese origin, introduced and cultivated in Manila, rarely 

 flowering. Otherwise known only from China. 



11. SYNEDRELLA Gaertner 



Annual, erect) branched, pubescent herbs. Leaves opposite, petioled, 

 toothed. Heads small, axillary, heterogamous, radiate, the ray-flowers fe- 

 male, in 1 or 2 series, yellow, the ligule short, 2- or 3-toothed. Disk-flowers 

 perfect, tubular, the limb 4-toothed. Involucre ovoid or oblong, the bracts 

 few, 1 or 2 outer ones usually foliaceous, the inner ones dry, like disk-scales; 

 receptacle small, with scarious flat scales. Achenes of the ray-flowers 

 dorsally compressed, 2-winged, the wings lacerate, those of the disk few, 

 compressed or 3-angled, often muricate, the angles of both terminating 

 in spines. 



Species 2 in tropical America, 1 now cosmopolitan in the tropics. 



1. S. NODIPLOEA (L.) Gaertn. 



An erect, dichotomously branched, glabrous or sparingly hairy, annual 

 herb, 1 m high or less. Leaves opposite, petioled, ovate-lanceolate to ellip- 

 tic-ovate, acute, flnely toothed,, base decurrent, 3-nerved, 7 to 13 cm long. 

 Heads sessile, axillary and terminal, nearly 1 cm long, cylindric, few- 

 flowered. Flowers yellow. Achenes black, the spines stout, sharp. (Fl. 

 Filip. pi. iOi.) 



In open waste places, very common, fl. all the year; throughout the 

 Philippines, and certainly introduced. Probably a native of tropical 

 America, now in: most warm countries. . 



12. ARTEMISIA Linnaeus 



Erect herbs or undershrubs,- usually strong-scented. Leaves alternate, 

 entire to pinnatisect. Heads small, racemose or panicled, solitary, or 

 fascicled along the branches. Flowers all tubular, the outer ones female, 

 1-S6riate, slender, 2- or 3-toothed; disk-flowers perfect, the bracts few- 

 seriate, outer shorter. Achenes small, faintly striate; pappus none. (In 

 memory of Artemisia, wife of Mausolus.) 



Species about 150 in north temperate regions, few in South America, 

 2 in the Philippines, the following introduced. 



1. A. VULGARIS L. Camaria, Damong-maria (Tag.). 



An erect, rank smelling, often suffrutescent herb 0.5 to 0.8 m high, 

 gray-pubescent, the stems leafy, branched. Leaves pinnately lobed, 5 to 

 14 cm long, gray beneath, nearly glabrous above, the lobes spreading or 

 ascending, irregularly coarsely toothed or lobulate, with stipule-like basal 

 lobes. Heads numerous, ovoid, 3 to 4 mm long, nearly or quite sessile 

 secund, seriate or fascicled on the elongated, spike-like, ascending panicle- 

 branches. (Fl. Filip. pi. S29.) 



Cultivated, fl. March-June and probably in other months; introduced 

 from Europe and widely distributed in the Philippines in cultivation 

 thoroughly naturalized in some regions. A native of Europe and 'Asia' 

 now found in many other regions. '
