Hob. Charles Island, Charles Darwin, Esq, 



Quite distinct from the former species, though so similar in habit and rami- 

 fication as to be easily confounded with it. Here the stems and whole plant 

 are of a lurid brown colour : the leaves are broader and rugose on the upper 

 surface between the lateral nerves (which in the preceding species are oblite- 

 rated) ; they are destitute of those curious large setee, similar to the stings of 

 a nettle, so prominent in G. Darwini ; their margins are less strongly recurved, 

 and the nerve beneath is neither so broad nor so prominent. The nucules also 

 are smaller and much narrower, and the radicle is larger, almost equalling 

 the cotyledons in size. 



117. TouRNEFORTiA RUFo-SERicEA, /TooA.^/. ; fruticosa, crccta, ramosa, velu- 

 tino-tomentosa, foliis petiolatis ovato-oblongis acuminatis integerrimis,

Hab. James Island, Charles Darwin, Esq, 



Tota pileis sericeis rufo-brunneis dense velutino-tomentosa. Rami teretes, crassitie pennae 

 anserinae. Folia 2-4-uncialia, 2-2^ unc. lata, utrinque velutina, tomento sericeo nitido, 

 pilis demiim canescentibus, venis subtus prominentibus ; petiolis subuncialibus. Spicae 

 8-10, pluries dichotome ramosae. Calycis segmenta ovata, acuta. Corolla 2 lin. longa, 

 extus villosa, pilis pallidis, limbo patente 5-fido plicato. 



I entertain little hesitation in referring this, in the absence of fruit, to the 

 neighbourhood of T, velutina, H. B. K., from which it mainly differs in the 

 dense inflorescence, more copious silky clothing of hairs, and in the leaves 

 being neither cordate at the base nor white underneath.
