6 I. EANUNCULACE.E (oliver). [Clematis. 



Moramb. Distr. Mangauya hills, 3000 ft. alt., Dr. Kirk ! 



Nearly related to C. Bojeri, Hook. Ic. Plant. 10, of Madagascar, as weU as to C. Stanleyi ; 

 differiDg from the latter in the round-based petiolulate, coriaceous or rigid leaflets of the 

 lower leaves, the prominent venation beneath, and generally glabrescent or thinly pubescent 

 (not silky) foliage. 



3. C. Stanleyi, HooJc. Ic. Plant. 589. Erect, 2-4 ft., more or less 

 caespitose, from a woody base, giving off, above the middle, axillary, erect, 

 1-flovvered, often bracteate peduncles, shortly tomentose, silky or pubescent. 

 Leaves very various, simply pinnatisect, .5 -foliolate, the lateral leaflets ob- 

 long-cuneate, acute, with but 1 or 2 lateral teeth, or leaflets 3-5 -fid, with 

 very obtuse segments, or leaves bipinnately divided, leaflets oblanceolate- 

 cuneate, acutely incised, more or less silky on both surfaces. Bracts usually 

 incised, 1 in. long or much less, at various distances below the flower. 

 Flowers 1^-2^ in. diam. Sepals 4-6, thick, closely tomentose, very ob- 

 tuse, broadly imbricate. Heads of fruit beautifully silvery ; plumose tails of 

 the achenes recurved.

 iu the Macalisberg and Transvaal, south of the tropic. 



4. C. Thunbergii, Steud.; Harv. Ft. Cap. i. 2. Climber. Branches 

 minutely pubescent or glabrous. Leaves various, pinnati- or ternati-sect, 

 occasionally bipinnately divided, with 3-foliolate pinnae ; leaflets ovate, ovate- 

 cordate or -lanceolate, broadly and unequally crenately toothed or incised ; 

 teeth mucronulate, thinly silky-pubescent or glabrate, 1-2^ in. long, 1-1^ 

 broad, but very variable in size. Flowers f-2 in. diam., in axillary or ter- 

 minal, free- or many-flowered panicles. Buds, when diy, frequently pointed. 

 Sepals elliptic-oblong or broadly lanceolate, usually acute or narrowed above, 

 more or less silky or pubescent on both surfaces. Filaments compressed, 

 pilose or ciliate below. Carpels silkv. — G. hirsuta, Guill. et Perr. Fl. Seneg.

liO^er Guinea. Huilla, Angola, Dr. Welwitsch ! 



Var. glaucescens. Abyssinia, Schimper I Billon. C. glaucescens, Fresen. in Mus.

Dr. Welwitsch's specimens have larger flowers than the rest, but do not otherwise differ. 



Very nearly allied to C. brachiata, Thunb., and doubtfully distinct. The acute flower- 

 buds appear generally to distinguish it, as pointed out by Dr. Harvey. G. brachiata, of 

 Schweiufurth and Ascherson's Enum. of Nile Plants, I presume to be the same. 



5. G. simensis, Fresen. in Mus. Senck. ii. 267. Branches glabrous, 

 the extremities often minutely puberulous. Leaves pinnatisect ; leaflets mem- 

 branous, on rather long petioles, usually 5, 3, or reduced to 1 towards the 

 extremities ovate or ovate-lanceolate, more or less acuminate, base rounded 

 or subcordate except in the naiTOw-leaved forms, crenate-serrate ; the teeth 

 mucronulate usually glabrous on both surfaces, 2-4 in. long, 1-2 in. broad. 

 Unifoliolate leaves sometimes more or less deeply trifid. Panicles many- 

 flowered. Pedicels slender, ^1 in. Flowers about f in. diam. Sepals ob- 

 long or oval, obtuse or somewhat pointed, usually minutely pubescent outside, 

 shortly silky-hairy within. Filaments pilose below. Carpels hairy, tails 1 in. 

 or more in length.
