Conyza.~\ composite. 177 



About Victoria, Wilford. Extends in northern India from Kamaon and Nepal to Sikkim 

 and Khasia. 



14. BLUMEA, DC. 



Flower-heads heterogamous. Florets all tubular, the outer ones very nu- 

 merous, in several rows, female and filiform, those of the disk usually few, 

 hermaphrodite and broader. Involucres imbricate, the bracts in several rows, 

 the inner ones linear and pointed. Anthers with short fine simple tails. 

 Style-branches filiform. Keceptacle nearly flat, naked. Achenes usually 

 somewhat compressed, striate or ribbed. Pappus of numerous capillary 

 bristles, in a single series. — Annual or perennial herbs, sometimes half- 

 climbing. Leaves alternate. Flower-heads in terminal pyramidal or oblong 

 panicles, sometimes contracted, spike-like or clustered. 



A considerable genus, confined to the warmer regions of the Old World, some of them 

 ubiquitous and variable weeds, upon which a large number of spurious species have been 

 fabricated. 



Flower-heads all distinctly pedunculate. 



Stems winged. Flower-heads ovoid, nodding 1. B. alata. 



Stems not winged. 



Half-trailing perennial. Leaves glabrous. Flower-heads few, 8-9 



lines diameter 2. B. chinensis. 



Erect annual. Leaves pubescent. Flower-heads numerous, about 



4 lines -. . . . 3. B. glandulosa. 



Flower-heads, at least the upper ones, sessile and clustered. Annuals. 

 Leaves oblong or obovate-oblong, the upper ones sessile. Involucre 



about 4 lines long 4. J?, hieracifolia. 



Almost all the leaves stalked and broadly obovate. Involucre 2-3 lines. 



Leaves rather firm. Panicle oblong, dense 5. B. lacera. 



Leaves thin and membranous. Panicle looser 6. B. 



1. B. alata, DC. Prod. v. 448; Wight, Ic. t. 1101. A tall stiff erect 

 branching perennial, covered with a short rusty or dingy, often glandular, 

 pubescence. Leaves undivided, elliptical or oblong, toothed, forming wings 

 along the stem by their decurrent margins. Flower-heads on short peduncles, 

 nodding, forming a terminal oblong or pyramidal leafy panicle. Involucre 

 near 5 lines long, ovoid, the scales firmer and broader than in the following 

 species, and more like those of a Pluchea. 



Hongkong, Seemann, Hance. Found in eastern Africa down to Port Natal, in Ceylon, 

 the Indian Peninsula, and the hilly districts of northern India. 



2. B. chinensis, DC. Prod. v. 444. A tall weak or trailing branching 

 perennial, glabrous, except a minute rusty pubescence on the upper part of 

 the stem and on the panicle. Leaves shortly stalked, not decurrent, oblong, 

 acuminate, 3 to 4 in. long, with a few small callous teeth, green on both sides. 

 Flower-heads pedunculate, few, broad, erect, in a terminal leafless panicle. 

 Involucres 4 to 5 lines long, the outer bracts lanceolate, the inner linear. 

 Styles and anthers protruding much beyond the florets and the white pappus. 

 Style-branches filiform, acute, as in Vernonia. 



Tolerably common, trailing in ravines, Champion, Hance, Wright, Wilford. Also in 

 Penang and Java. 



3. B. glandulosa, DC. Prod. v. 438. An erect annual, often 2 or 3 ft. 

 high, and more or less covered with a glandular viscous pubescence. Leaves
