MALVACEAE. 255 



The specimens accord so well with the figure and description of the 

 Sida pinnata of Cavanilles (which, however, was gathered on Chim- 

 borazo), that they may confidently be referred to that species. True, 

 the flowers of S. pinnata are said to be sessile in the axils; but the 

 peculiarity in the insertion might readily be overlooked in this, as it 

 certainly has been in several other species. The leaves, also, are said 

 to be tomentose-canescent underneath, which is a natural oversight, 

 since the lower surface, if either, is the downy one in most plants. 

 But all the PhyManthophorous Malvastra have the ttpjper surface more 

 downy than the lower.

Hab. Alpine Cordilleras of Peru, near Casa Cancha. (Also gathered 

 by Mr. M'Lean.) 



Plant growing in close, depressed tufts, half an inch to an inch 

 high, smaller in all its parts than the foregoing species ; the branches 

 of the caudex not so stout. Leaves crowded, 6 to 8 lines long (include 

 ing the petiole) glabrous beneath, white-tomentose above with a very fine 

 and close tomentum, pinnately parted into 3 to 5 pairs of approximated 

 segments, which are again deeply trifid ; the lobes linear or narrowly 

 oblong, entire, or those of the lowest and largest pair 2-3-lobulate ; 

 the margin involute. Petiole wingless and naked above ; the scarious 

 stipules adnate towards the base only, scarcely if at all ciliate. Flower 

 sessile on the petiole next its base, a little below the free portion of the 

 stipules. Involucel none. Calyx campanulate, five-cleft to below the 

 middle, puberulent externally, the tube marked with five brown spots 

 within next the base ; lobes triangular-ovate, acute, canescent-tomen- 

 tose inside. Petals deep red, greenish or yellowish at the base, at first 

 oblong-spatulate and 4 or 5 lines long, of a rather firm texture, not
