genera, too, are nearly the same. Sisymbrium, (No. 301), 
called berros by the Creoles, is similar, in every respect, to 
our water-cresses, and is held in repute as an antiscorbutic. 
Cremolobus Peruvianus (No. 85), is a large shrub, found on 
the middle region of Pichincha, chiefly towards the western 
side. But of all the plants belonging to this Order, the 
Drabe must be allowed to hold the first rank. In Europe, 
one would hardly think it worth while to cultivate the conti- 
nental Drabe, so little attractive are they; whereas, on the 
Andes, we have several species that attain the dignity of 
shrubs, adorned with large flowers, purple or white. Of this 
description is Draba violacea (No. 83.) It is a very elegant 
shrub, with deep purple flowers and downy foliage, being pe- 
culiar to the lofty ridges of the Andes, to the southward of 
the Asuay, where it is often associated with the no less ele- 
gant Altsræmeria glaucescens. Draba grandiflora? (No. 84), 
adorns the bare rocky precipices of Chimborazo. It can 
scarcely be called a shrub, but is remarkable for its large 
snowy blossoms. Draba alyssoides (No. 82), first occurs at an 
elevation of 12,000 feet, and reaches to the snow limit. Of 
all the species it is the most generally distributed. Draba 
aretioides (No. 78) is found near the summit of Pichincha, 
where the ground is frequently sprinkled with snow, growing 
on the sand, in the shape of a compact vegetable mass. Itis 
associated with Sida Pichinchensis, (No. 105), and the Cul- 
cilia, (No. 228, 229, 230, 231). Draba—(No. 81), occurs 
only on the Cerro del Altar, near the mine of Condorasto, at 
an elevation of 14,496 feet. 
The collection contains altogether seven species of this in- 
teresting genus, whereas three only are described by Kunth 
as natives of this country. 
The same observations as to geographical position will 
apply to the Umdellifere. They are not, however, so much 
restricted as to climate, and consequently occupy a wider 
range on the flanks of the Andes. Hydrocotyle—(No. 116), 
extends a long way down, amid the dense and misty 
forests that overhang the Pacific; although most of the
