THE GENUS NOTOTRICHE, 211 
Some species, however, particularly those with bi-pinnatifid leaves, are found 
associated with grass and other plants, which form a general carpet on the more rocky 
soils; amongst such may be mentioned W. longirostris, which was found growing 
amongst patches of Azorella, and N. aristata, found in a rocky alpine valley covered 
with dwarf vegetation. 
N. Mandoniana and N. purpurascens are said to grow in grass amongst rocks, and 
N. artemisioides and N. acuminata on grass steppes. It is unfortunate that information 
is so scanty as to the habitats of the various species, but it appears that those species 
which tend to form definite cushions are more likely to be found in bare rocky places, 
while those which are unbranched and form only a single rosette are more usually 
associated with grass and other plants. 
N. pichinchensis, according to Jameson, ** forms a sort of dense turf at an elevation of 
15,000-16,000 feet, and from the beauty of its flowers enlivens in no small degree the 
gloomy aspect of the surrounding scenery." 
A considerable amount of valuable information on the general vegetation and the 
climatic condition of the Peruvian Andes is given by Weberbauer *, including a careful 
account of the meteorology and of the soil temperatures. Various biological features 
of the high Andean vegetation, with an account of some of the formations and of their 
relation to the soil, are also discussed by him. 
COLLECTORS. 
A short note on the numerous collectors and botanists who have travelled in the 
Andes and gathered the various species of Nototriche may not be out of place at this 
point T. 
Amongst the earliest was the Abbé Cavanilles, who sent home plants from Quito which 
are now at Madrid. It is unfortunate that it has been found impossible to see these 
specimens or to obtain definite information about them. Humboldt and Bonpland in 
the same region collected N. pichinchensis and N. phyllanthos, &c., and our herbaria 
have been plentifully supplied from this part of Ecuador by the activity of Jameson, 
Spruce, Hartweg, Sodiro, and others. 
To the south, in Bolivia, the earliest collections were made by D'Orbigny in the 
neighbourhood of Potosi, and by Meyen to the south of Lake Titicaca, but it is to 
Weddell, Mandon, and Richard Pearce j, one of Veitch's travellers, that we mainly owe 
our knowledge of this region. From the desert of Atacama, R. A. Philippi brought 
back several curious little species which appear to be confinéd to northern Chili, whilst 
Gay collected N. compacta in the Cordillera of Santiago, S. Chili, which appears to be 
the southern limit of the genus. 
Hieronymus, Risdal, and Lorentz discovered several species in the mountains 
of Northern Argentina, whence Fries has lately brought home some further specimens.
