Too near to this to justify specific separation is a plant of which we have a frag- 
ment collected by Colonel Grant at Karagué, 1° 42’ S, Lat. near the Victoria N’yanza. 
59. V. Grantii, Oliv. in Trans. Linn. Soc. Lond. xxix. p. 92,

minutely hispid above, at first tomentose, at length glabrous beneath, 
4-6 in. long, 14-2 in. broad, narrowed to a petiole of }-lin. Capitula 
1} in. diameter, on peduncles }-? in., in terminal cymes of about 4, 
hoary-tomentose ; intermediate bracts with an ovate acuminate ap- 
pendix and distinct median nerve. Corolla not seen. Achenes 
20-striate, strie often faint, shortly hispid with ascending tawny hairs. 
Sete wholly free, finely pointed, scabrous.

Closely allied to V. Tenoreana, differing in the more distinct petiole, less serrate 
leaves at length glabrous beneath, less acuminate involucral scales and more finely 
pointed pappus-sete. 
60. V. adoénsis, Sch. Bip. ex Walp. Rep. ii. p. 946. Upper portion 
of erect stem terete, sulcate-striate, puberulous or minutely tomentose. 
Leaves petiolate, oblong- or ovate-lanceolate, acute, unequally or den- 
ticulate-serrate, scabrid or minutely hispid above, closely tomentose 
beneath, 3-5 in, long, on petioles of 4-4 in. more or less. Capitula 
1-2 in. diam., pedunculate, in terminal few- or many-headed lax 
Corymbose cymes; bracts spreading or recurved, puberulous or mi- 
nutely tomentose, appendix of intermediate bracts oblong-ovate or 
elliptical, obtuse or broadly pointed, often mucronulate ; inner bracts 
nearly or quite equalling the pappus. Corolla gradually narrowed into 
the long tube. Achenes nearly equally 20-striate, tawny-silky ; pap-

ac M. Richard’s types. The receptacle becomes at length, at least in some cases, 
istinetly concave, as in V. Kotschyana. Dr. F. W. Klatt, in Ann. | Sc. Nat. Ser. v.
