472 A FLORA OF MANILA 
white hairs, base long-narrowed, apex prominently 3- to 5-toothed or -lobed, 
the lobes ovate to narrowly oblong. Heads in the upper axils, peduncled, 
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. NODIFLORA (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, finely 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. (FI. 
Filip. pl. 404.) 
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-seriate, 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. vutGaRIs 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 ecm 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. (FI. Filip. pl. 329.) 
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.
