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 setze, 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, Hook. fil. ; fruticosa, erecta, ramosa, velu- 
tino-tomentosa, foliis petiolatis ovato-oblongis acuminatis integerrimis,

Hab. James Island, Charles Darwin, Esq. 
Tota pileis sericeis rufo-brunneis densé velutino-tomentosa. Rami teretes, crassitie penne 
anserine. Folia 2—4-uncialia, 2-21 unc. lata, utrinque velutina, tomento sericeo nitido, 
pilis demüm canescentibus, venis subtüs prominentibus ; petiolis subuncialibus. Spica 
8-10, pluries dichotomé ramos. Calycis segmenta ovata, acuta. Corolla 2 lin. longa, 
extüs 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. |
