Erlangea aggregata, Hutchinson; species nova, affinis H. spissae, 8. Moore, 
sed foliis latioribus infra puberulis (nec tomentosis) supra minute puberulis 
dentibus patentibus, involucri bracteis abrupte acutis, pappo majore differt. 
Herba perennis; caulis erectus, laxe foliatus, molliter lanato-tomentosus, 
internodiis inferioribus 2 em. superioribus 5-7 cm. longis. Folia petiolata, 
ovato-lanceolata, subacuta, basi cuneata, 9-14 cm. longa, 4°5-6°5 cm. 
lata, tenuissime chartacea, serrata, supra minute infra distincte puberula ; 
nervi laterales sub angulo lato a costa abeuntes, utrinsecus circiter 15, 
graciles, infra tomentelli; petioli 1°5-2°5 cm. longi, tomentelli et pilosi. 
Inflorescentia trichotome ramosa, capitulis dense aggregatis ; pedunculi 
primarii usque ad 8 cm. longi, molliter tomentosi. — Capitula sessilia, 
circiter 8-flora. Involucri bracteae virides, marginibus hyalinis, plus 
minusve ovatae, acutae, usque adi4 mm. longae. Flores roseo-coerulei ; 
corolla circiter 5 mm. longa, lobis linearibus acutis ; antherae exsertae. 
Achaenia compressa, glabra; pappi setae paucae, caducae, vix 2 mm. 
longae, barbellatae.—J. Hurcurnson. 
The genus Erlangea is closely allied to the important 
Composite genus Vernonia, Schreb., from which, how- 
ever, it is readily distinguished by its reduced achenes 
crowned with a pappus composed of very short and 
caducous setae, incapable of playing any part in the 
distribution of the ripe fruit. The genus, as circum~- 
scribed in accordance with this striking feature, includes 
some four and thirty species, all but one of which are 
natives of Tropical Africa. The remaining species 1s a 
native of New Guinea, a circumstance which must, never- 
theless, be regarded as of no significance from the phyto- 
geographical standpoint, since the feature that admits 
the Eastern plant in question within this characteristic- 
ally African genus is, in spite of its practical utility, a 
somewhat artificial one. From the systematic stand- 
point the existence of this New Guinea plant is, however, 
Arrit—Jung, 1918.
