2 i. RANUNCULACE2E. [Clematis 



when occurring in tropical countries, are generally represented by 

 unattractive examples, as for instance in the case of Oxaliaese, 

 Primulacese, Salicacese, etc.; the Ranunculacese, however, nave 

 representatives worthy of the tropics.

 This genus affords an illustration of what occurs in certain 

 groups of plants, at least in tropical Africa— namely, that it is 

 composed of species nearly always scandent in the shady and moist 

 forests of the lowlands, but in the highlands and exposed regions 

 provided with a poor sandy-rocky soil it is represented by species 

 or their varieties remarkable for their erect habit. See Welwitsch, 

 Sertum Angolense, in Trans. Linn. Soc. xxvii. p. 30, observ. (1869).

Huilla — Erect, 1 to 1£ ft. high, sparingly branched ; lower leaves 

 simple, toothed towards the apex ; upper leaves pinnately trifid ; sepals 

 4 to 6, ovate-acuminate, white, 1J in. long. In shortly bushy, rocky, 

 rather dry stations, between Lopollo and Nene, at a place called Ferra 

 de Sola, not abundant ; fl. Feb., fr. April 1860. No. 1222. 



A perennial sparingly branched herb, 1£ to 2 ft. high, with large 

 whitish flowers. In bushy, sandy pastures, near Lopollo, February 

 and April 1860. Coll. Carp. 67. 



To this species Oliver (I.e.) referred a specimen collected by Grant 

 in the Usui district, 2£° S. Lat., and figured with this name in Trans. 

 Linn. Soc. xxix. i. tab. 1 (1872) ; that specimen, however, differs from 

 the type by its fruit having a much paler colour, and may perhaps belong 

 to C. Stuhlmanni Hieron. in Engl. Pflanz. Ost-Afrik. C. p. 180 (1895).
