THE GENUS NOTOTRICHE. 237 
Meyenii by Count Solms * and is allied to W. Orbignyana. The Berlin specimen is from 
Kunth's Herbarium and was collected, according to the label, from the “altos de Toledo,” 
Peru, at 15,000 ft., whilst the Kew specimen, which exactly agrees with this plant, bears 
the label “ Lobb, S. Chile," in the handwriting of Sir W. Hooker. In this latter case 
there is no doubt some mistake, and the habitat of WV. Meyeni extends, probably, from 
the country on the borderland of Chili, Peru, and Bolivia, as far as the shore of Lake 
Titicaca: owing to the fragmentary nature of the material, it has not been possible 
to make a complete diagnosis of this species. A resemblance to N. parviflora may be 
noticed in the form and cutting of the lamina and in the shape of the lobes, and 
N. borussica is very possibly allied to that species. It is, however, very distinct, 
particularly in its universal white tomentum. 
According to Weddell t, this species is only a variety of M. pAyllanthos, but the state- 
ment must have been made from superficial observation. 
Meyen in his description of this plant 1 states that the leaves are covered with silver- 
white hairs. The plants form small isolated rosettes growing amongst the black ash 
and the flowers are striped white and dark violet or almost black ; he goes on to say, in 
reference to the colour of the flowers, * wesshalb diese Blümchen, in dem sie die 
Preussische National-Farbe zeigten, einen um so grósseren Reiz für uns hatten, und 
wir auch der Art den Namen Sida borussica gegeben haben." 
This species was found by Meyen on the volcanic ash near the ‘alto de los Huesos,’ 
a more or less flat tract of country lying at an elevation of about 13,300 feet on the 
borders of the departments of Arequipa and Puno at the foot of the southern slopes of the 
cone of the volcano El Misti. This volcanic ash, in which several species of Wototriche 
flourish, has been derived from the volcano which rises directly from the plateau.
