Tribe IV.— XNUIiOI3>I:,S:. 



26. BIiVKEA, DC. 



Annual or perennial, glandular pubescent or wooUy herbs. Leaves alternate,, 

 usually toothed or lobed. Heads corymbose panicled or fascicled, rarely ra- 

 cemed, heterogamous, disciform, purple rosy or yellow ; outer fl. oo -seriate, $ , 

 fertile, filiform, 2-3-toothed ; disk.-fl. ^ > few, fertile, tubular, slender, limb- 

 6-toothed. Involucre ovoid or campanulate ; bracts c» -seriate, narrow, acute, 

 soft or herbaceous, outer smaller ; receptacle flat, naked. Anther-hoses sagittate, 

 tails small, slender. Style-arms of Q flattened or almost filiform, rarely con- 

 nate with the adjoining anthers. Acheaes small, subterete or angled, ribbed 

 or not; pappus 1-seriate, slender, often caducous.— Disteib. Species about 60,. 

 tropical and subtropical Asiatic, African and Australian. 



This genus is eminently characteristic of India, and the species may be called the 

 Groundsels of that country. There is no more unsatisfactory genus than this ; it is 

 distinguished irom Laggera only by the tailed anther-cells, and this is not a very con- 

 stant character, the anthers of some states of B. virens having no tails, whilst forms 

 of Laggera have them ; Kurz, indeed, suggests (with much probability) that some 

 Laggeras are sexual forms of Elumeas. Clarke finds generally in Blumea, that func- 

 tionally $ heads occur, the disk-flowers, though ^ in form, having only rudimentary 

 stamens, and that in the case of the common B. oxyodonta he has never found 

 perfect 5 flowers, nor has Kurz. The divisions of the Genus here proposed are 

 most unsatisfactory, and I fear that the specific diagnoses are not much better. Th& 

 glabrous or puhescent receptacle is very difficult to see; the size of the head is 

 tolerably constant ; the form and number of the invol. bracts are difficult to describe ;. 

 the very minuter achenes are tolerably uniform ; the foliage is sportive to an extra- 

 ordinary degree, as is the pubescence ; gland-hairs are common to most species, but 

 the amount varies with the dryness of the locality. I have not been able to follow 

 Clarke's disposition of the species at all closely, they want a careful study in situ, and 

 under cultivation.
