the former, its range being far wider and it being further closely allied to three or four Chilian congeners. I have 

 diligently compared Professor Jameson's specimens both in flower and fruit, gathered on Pichincha, with those of 

 Capt. King from Port Pamine in an equally good state, without being enabled to detect even the differences of a 

 variety in the foliage or inflorescence of either. The oblong form of the leaflets similar at both extremities and re- 

 gularly serrated along the whole margin is characteristic, but far more so is the calyx, densely clothed with stiff 

 straight hairs, the slender filament, and small didymous anther ; also the villous fruit, with generally two slender 

 arista;. The figure in Ventenat's ' Hortus Celsianus' is excellent.

The chief points of distinction between this and the A. Icevigata will be found in the notes upon that species. 

 The present is the more common plant of the two in the Falkland Islands.

A plant so very similar to A. ascendens that I long considered it to be a variety peculiar to the remote loca- 

 lity it inhabits. Though the characters I have used to distinguish them are minute, they are very important. Besides
