 clavate, pale brown, glabrous, not ribbed. Pappus of about 20 

 pure white uniform setae -^ in. long. — Central Madagascar, Dr. 

 Parker! Native name Anampozacanj. Allied to the Canarian and 

 Abyssinian C. Guiiani, Willd., and the Japanese C. japonica, Less. 



HeUclinjsuui corcUfoliiun , DC, var. leucocephalum, Baker. — Bracts 

 of the involucre white, instead of bright brick-red, as in the typical 

 form. — Central Madagascar, Dr. Parker I Native name Fotsiava- 

 dika. 



Helichrysum concretum, n. sp. — A shrub, with woody branches, 

 densel}' clothed with short spreading grey hairs. Leaves crowded, 

 oblanceolate, sessile, about ^ in. long, acute, entire, moderately firm 

 in texture, flat, triplinerved, thinly matted above, densely pubescent 

 beneath. Heads aggregated 4-8 together in globose clusters, which 

 are enveloped in the lower half in a mass of brownish-white 

 tomentum and arranged in dense terminal corymbs. Involucre 

 cylindrical, ^ in. long, the portion that emerges from the tomentum 

 consisting of 8-10 bright lemon-yellow glabrous obtuse oblanceolate 

 caducous imbricated bracts. Flowers not more than 3 to an in-

 petioled, oblong or ovate-oblong, obtuse, sharply dentate above the 

 entire deltoid base, 1-1 i in. long, subcoriaceous, green and glabrous 

 on both surfaces. Heads very numerous, arranged in an ample 

 oblong panicle, with dense corymbose branches ; pedicels very 

 short, pubescent. Involucre cylindrical, glabrous, 1 lin. diam., 

 2 lin. long, equalling the tubular flowers ; inner bracts 4, rigid, 

 brown, glabrous and imbricated, and 3-4 minute ones at the base. 

 Flowers about 10, the outer with minute yellow ligules. Achene 

 slender, glabrous, ^ lin. long. Pappus ^ in. long, of very numerous 

 pure white bristly hairs. — Forests of East Betsileo, irtrow 226 ! 

 Gathered previously by Dr. Lyall. Habit and capitula of the 

 Mauritian Faujasia Jiexuusa, DC. The Madagascar plant referred to 

 that species in my ' Flora of Mauritius ' really belongs here. 



Senecio betsiliensis, n. sp. — A tree, with woody slender terete 

 purplish branchlets with a little white cottony tomentum. Leaves
