214 MR. A. W. HILL—REVISION OF 
Of the two groups so defined the smaller deserves more particular attention. 
Included in it are to be found species with every type of leaf-form, &c.; and though 
it is evident that from a consensus of characters a relationship exists between certain of 
the species, yet the position of the others is by no means clear. 1f, then, the character 
of the corolla is to be taken as a starting-point in the evolution of the species, it would 
appear that the independent appearance of similar leaf-forms in the two groups must be 
accounted for, and for this there does not seem at present to be sufficient evidence 
to warrant the assumption *. 
It seems therefore to be of more value and also more within the limits of probability 
if in this genus the form of the leaf is regarded as affording a more certain indication 
of the relationships of the different species, and it is on this assumption that the 
following account of the genus Nototriche has been prepared. 
THE GENUS NOTOTRICHE. 
Nototriche, Turcz. emend. et ampl. A. W. Hill, in Engl. Bot. Jahrb. xxxvii. p. 578. 
Species about 70, Andes of South America in Ecuador, Peru, Bolivia, Argentine to 
the cordillera of Rioja and Chili as far south as the cordillera of Santiago. 
In Tropical South America between 3900 and 5700 m.; in Temperate South America 
above 2500 m.

* N, Jamesonii from this point of view would appear to be far removed from N. phyllanthos, &c., to which 
it appears on other grounds to be closely united. JV. pedicularifolia, N. Lorentzii, and N. sulphurea would also be 
far removed from species to which on other grounds they appear to be closely allied. The other seven species z 
the first column of the footnote on p. 213, however, show certain points of similarity which may indicate a real 
alliance, though they appear to be strikingly different from the three species cited above.
