binervatis nervis lateralibus evanescentibus, amentis gracilibus

A native of Mexico, discovered by M. Botteri, after whom it is 
named. 
Stems sparingly branched, procumbent at the base, the upper 
part ascending, slender, terete, green or tinged with purple, 
clothed with short spreading gray pubescence. Leaves -in threes, 
decurved, the petioles three to six lnes long, pubescent, erecto- 
patent, the blade obovate, subacute, moderately fleshy in texture; 
when full-grown about an inch long, minutely downy on both 
sides, a pale rather glaucous green above, very pale green 
beneath, the veins immersed, three principal ones branching from 
the apex of the petiole, the lateral ones vanishing about half-way 
up. Catkins slender, cylindrical, on very short erecto-patent downy 
peduncles on the end of the stem and from the axils of a few of 
the leaves, fifteen to eighteen lnes long when fully developed. 
Flowers dense, the bracts orbicular, peltate, the papillose sessile 
style obliquely placed on the partially emergent ovary. 
Closely allied to P. blanda (Hook. Exotic Flora, t. 12), from 
which it principally differs by its broader leaves and shorter 
peduncles and catkins. In the general habit and veining of the 
leaves it resembles P. rotundata, H. B. K., which has the leaves 
in pairs only and a centrical stigma.

Many of the Peperomias, and this among the number, have an 
elegant habit of growth, and are well suited for baskets or shallow 
pots, which they soon cover with their branching stems, and 
hang prettily over the rims. This species should be grown in 
turfy peat in the stove, and allowed plenty of moisture, and never 
exposed to the sun. I received it from Mexico.—W. W. S.
