2 T. RANUNCULACEiE. [Clematis 



when occurring in tropical countries, are generally repi-esented by- 

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

 Primulaceae, Salicaceee, etc. ; the Eanunculaceae, however, have 

 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, 1^ 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 a Stuhlmanni Hieron. in Engl. Pflanz. Ost-Af rik. C. p. 180 (1895).
