 natis supra parce pilosis, stipulis late ovatis membranaceis concavis integerrimis, scapo foliis bis longiore

Precedent! liabitu simillima ; sed statura, foliis basi non cordatis, petalis glaberriniis et prsecipue bractearum 

 forma distinetissima. Petioli a pollicares, laminae subaequilongi. Scapus petiolis bis longior, apicem versus arcuatus 

 et ibi bibracteatus ; bractese erectse, bneari-lanceolatse, acuta?, 2A lin. longse. Sepala hneari-oblonga, acuminata, 

 petalis -j- breviora. Petala flava, 4 bn. longa. Stylus stujmauue ut in priore. 



A very distinct and probably rare species, allied to the last, but essentially different. The leaves are gene- 

 rally reticulated on the under surface.

 obovato-cimeatis apice tridentatis trifidisve plerumque basi utrinque unidentatis, petiolo brevi in stipulas 

 vaginantes dilatato, scapo brevi valido arcuato basin versus bracteolato, bracteis oblongis obtusis, sepalis 

 oblongo-lanceolatis basi deorsmn productis, petalis oblongis obtusis glaberrimis, ealcare nullo, stylo gracili 

 apice obhque truncato, capsida globosa. V. tridentata, Menz. 3ISS. in DC. Prodr. vol. i. p. 300.

Species pusilla, prima visu Caltkam appendiculatam referens. Caules graciles, 1-2 imc. longi, vage ramosi, 

 prostrati, superne fobosi. Folia valde coriacea, \ unc. longa, subcbsticha, erecto-patentia, glaberrima, subnitida, 

 venis inconspicuis. Scapus sobtarius, erectus, apice arcuatus, fobo A longior, basi bracteatus, bracteis pro planta 

 majuscubs. Flores nutantes, parvi, coendei. Sepala coriacea, sub 1A bn. longa. Petala sepabs bis longiora, line- 

 ari-oblonga. Anthem orbiculatse, in laminam membranaeeam produeta?, filamentis brevissimis. Stylus gracibs, 

 arcuatus, apice obbque truncatus, cavus, nee bilobus. Capsula magna, pendula, globosa, valvis coriaceis. 



A very singular bttle species, agreeing in the shape of the style and stigma with the V. Magellanica and 

 V. Comrnersonii, but of a totally different habit and fobage, which approach more nearly to some of the species of 

 the Asterias group. It is probably a common mountain plant throughout Fuegia; but, from its small size and 

 prostrate mode of growth, readily overlooked.
