Differt a typo sepalis longioribus acutioribus, foliis magis dis-

The description of this species above cited is fuller and more 

 accurate tlian that subsequently given in the ' Prodromus,' but 

 does not represent the ordinary form. It was draAvn up from 

 specimens in the Paris Museum collected by Dombey in Peru, 

 and would appear to have much smaller flowers than I find in the 

 numerous specimens existing in the Kew Herbarium. DeCan- 

 dolle's words are, " sepala patentissima orato-oblonga acuta sta- 

 minibus duplo fere breviora j" whereas, in what I presume to be 

 the ordinary form of the species, the sepals are about once and a 

 half the length of the stamens, and are often somewhat reflexed 

 when in full flower. The Chicla plant, which apparently inhabits 

 a higher zone than any of the other specimens I have seen, is 

 extremely ornamental, the large crowded flowers, of a delicate 

 sulphur-yellow, often completely concealing the bushes over 

 which the plant climbs. The leaves and petioles are slightly 

 pubescent, but the broadly ovate, entire, or slightly toothed bracts, 

 2 or 4 in number, which form a detached involucre about the 

 middle of the one-flowered peduncle, are covered with soft villous 

 hairs. The leaves are much divided, bipinnatipartite, with stalked 

 three-lobcd pinnules.

appearance of the rare Pyrenean T, macrocarpum. 



Banuncultis chiclensis, n. sp. Chicla, in moist ground! 



Bipedalis et ultra, indumento totius plantae e pilis subadpressis 

 hirtulo ; radice e fibris validis subincrassatis ; foliis radicalibus et 

 cauliuis inferioribus pinnatiscctis ; piunis alternis trisectis vel 

 pinnatifidis, superioribus oblongo-cuneatis varie incisis; floribus 

 majusculis longe pedunculatis ; petalis 5-10 angustis oblongo- 

 cuneatis, apice truncatis vel leviter emarginatis, linels tenuibus 

 obscuris notatis; acheniis compressis acute carinatis, in rostrum 

 longiusculum, sa?pe nee semper recurvum, sensiin angustatis. 



A very distinct species, especially remarkable for the form of 

 the petals.
