260 MR. A. W. HILL—REVISION OF 
by Baker under this species, has been separated and described as a new species, 
Nototriche Matthewsii, to which perhaps the other Peruvian specimens may belong 
(p. 248). It also seems likely that the Sida pinnata of Presl, said to come from Peru, 
is not the S. pinnata, Cav.

Peru: High Cordillera near Casa Cancha, Pickering. 
The specimen collected by Pickering is referred by Gray to Sida acaulis, Cav., and he 
has been followed in this determination by Weddell and Baker fil. The original 
specimen was not seen, but he says ** our specimen closely resembles the figure given by 
Cavanilles, but the corolla does not appear to have been yellow." As in the case of 
S. pinnata, Cav., it seems unlikely that the specimens from Peru and Ecuador belong 
to the same species, it will be better to retain the name Sida acaulis, Cav., for the 
species from Ecuador and to confine the name M. Cavanillesii to the Peruvian specimen 
until the two plants have been seen and compared.

It seems unlikely, judging from the locality, that this plant can be a variety of 
Nototriche pichinchensis; the description, which only relates to the colour of the 
flowers, is too meagre to afford any clue as to the nature of this variety or species.
