beneath, the younger ones on both sides silky ; corymbs few-headed, 
subterminal, or from the axils of the upper leaves, forming an inter- 
rupted thyrsus ; pedune. and invol. densely silky; invol. scales narrow- 
linear, equalling or overtopping the disc ; corolla of the disc-fl. exter- 
nally glandularly tuberculated. B. Dregeana, DC. l.c.. Also B. Wightiana,

Stem 1-2 feet high, subsimple. Radical leaves and lower stem-leaves tapering 
into a slender petiole, 2-3 inches long, 1-14 wide, exactly obovate ; upper leaves 
more sessile, oblong or lanceolate, sometimes acute, 1-2 inches long. Invol. scales 
often tipped with crimson. Style of male fi. bifid.—I gladly follow Bentham (Hong 
Kong Fl. p. 178-179) in uniting the Bl. Dregeana of 8. Africa with the common 
Indian weeds above quoted. 
2. B.alata (DC. 1,c. p. 448); stem herbaceous, erect, branched, clothed, 
as well as the leaves, with a short, glandular, rufous pubescence ; leaves 
elliptic-oblong, denticulate, decurrent along the stem as narrow, entire or 
distantly-toothed wings ; peduncles short, axillary, one or few-headed, 
disposed in a panicle or raceme; heads cernuous; inv. scales in several 
rows, the outer lanceolate, leafy, squarrose-reflexed, pubescent; inner 
linear-acuminate, equalling the flowers ; cor, of disc-fl. glabrous. Conyza 
alata, Roxb. Erigeron alatum, Don. Prodr, 171.

2-3 feet high, more or less densely glandular-pubescent, rusty-coloured. Leaves 
2-3 inches long, 4—$ in. wide, veiny, rather harsh to the touch. Heads in a simple 
or branched leafy raceme, ending the branches ; invol. scales remarkably squarrose, 
with similar rough gland-pubescence as the leaves—Sent also by Mr. Mann from 
the Cameroon Mts.—I find the wings frequently toothed on the Cape specimens. 
3. B. pterodonta (DC. 1. c. 448) ; stem herbaceous, erect, branched, 
clothed, as well as the leaves, with short, glandular pubescence; leaves 
ovate-oblong, acuminate, denticulate, decurrent along the stem as broad- 
ish, distantly-toothed wings ; heads on long, slender, naked pedicels, dis- 
posed in a loose panicle ; invol. scales pluriseriate, the outer squarrose 
and minutely glandular, the inner erect, linear-acuminate, scarious ; 
cor, of dise-fl. glabrous. 
Haz. Magalisberg, Burke ¢ Zey.! 912. (Herb. Hk., D.) 
2-3 feet high, loosely branched. Lower leaves not seen ; medial oblong, upper 
ovate, all sharply taper-pointed. Pedicels 1-14 inch long, thread-like, straight or 
curved, Invol. pale, all the scales very narrow.—Differs from B. alata in being 
green, not rusty; with shorter and less copious pubescence; broader wings to stem ; 
acuminate leaves ; and long, slender pedicels. 
4. B. Gariepina (DC. 1. c. 448) ; suffruticulose, much branched, all 
parts densely sulky-canescent; leaves broadly-linear, entire, subacute, de- 
current along the stem as narrow, entire wings; heads shortly pedicel- 
late, corymbulose at the ends of short branchlets, forming a leafy pani- 
cle ; invol. scales pluriseriate, linear-subulate, erect, imbricated, silky, 
equalling the disc ; cor. of disc fl. setulose on the teeth,
