Trifolium.] xlvii. § papilionace.e (baker). 55 



an inch long-, glabrous. Peduncles exceeding leaves. Flowers about 

 20 in a dense head ; bracts equalling the calyx. Calyx sessile, 2| lines 

 long-, becoming dilated and inflated as in T.fragiferum, the deltoid acu- 

 minate teeth half as long as the tube. Corolla violet, twice as long as 

 the calyx. Pod ovoid, 2-seeded. 

 Nile Land. Abyssinia, Ataba, Steudner. 



4. T. umbellulatum, A. Rich. Fl. Abyss, i. 172. Stem a foot high, 

 erect, glabrous, % branched from the base. Stipules membranous, lower 

 part sheathing- the stem, the free points ovate-acuminate. Leaflets 

 elliptical, obtuse, rarely subovate, sharply toothed. Flowers in heads 

 of 3-10, surrounded, by a whorl of short blunt bracts. Calyx short- 

 stalked, tube 10-nerved, teeth lanceolate, rather longer than the tube. 

 Corolla bluish, slightly exceeding the calyx. Pod compressed, 

 elliptic-oblong, twice as long as tube, apiculate, 5-seeded. 



Nile Land. Abyssinia, Quartin- Dillon and Petit. 



This we have not seen. The author compares it with and considers it near T. sub- 

 rotundum. 



5. T. Quartinianum, A. Rich. Fl. Abyss, i. 169. Stem a foot high, 

 suberect, glabrous. Stipules 1 in. long, adnate to the petiole for the 

 lower three-quarters, the point lanceolate. Petioles 1—2 in. long, gla- 

 brous. Leaflets subsessile, narrow-oblong, glabrous, 1J— 2 in. long, 

 \-\ in. broad, finely toothed, blunt. Flowers in a few long-stalked 

 dense rounded heads, surrounded by a whorl of imbricated ovate 

 scariose strongly veined bracts J in. broad. Calyx subsessile, 4 lines 

 deep, finely striated, teeth lanceolate acuminate, reaching halfway 

 down. Corolla purple, half as long again as the calyx. Pod oblong, 

 pointed, about equalling the calyx, 1-2-seeded. 



Nile Land. Abyssinia, Schimper ! Quartin- Dillon ! 



In general habit and the heads of flowers resembling T. pratense and medium. 



6. T. acaule, Steud. in Schimp. PL Abyss. No. 587. Root thick, 

 woody, a foot long. Stems very short, densely csespitose. Stipules 

 glabrous, adnate at the base only, the free points setaceous. Petioles 

 at most only equalling the sessile oblanceolate leaflets, which are gla- 

 brous, rigid, strongly veined, finely toothed, J in. long by half a line 

 broad. Flowers in short-stalked clusters of 2-3 together, sometimes 

 solitary, clusters surrounded by lanceolate-subulate bracts, which are 

 considerably shorter than the pedicels, which are J in. long. Calyx J in. 

 long, glabrous, with a few prominent nerves, the teeth lanceolate, 

 reaching one-third of the way down. Corolla nearly twice the calyx. 



Nile Land. Abyssinia, Schimper! 

 A very well-marked species. 



7. T. Schimperi, A. Rich. FL Abyss, i. 173. Stems 6-12 in. long, 

 annual erect or spreading, copiously branched. Stipules scariose, an 

 inch long, the lower third sheathing the stem loosely, the point linear- 

 setaceous. Petioles 1-1 J in. long. Leaflets sessile, linear, 1-1 h in.
