ARACHIS MARGINATA, Gardn. 
Perennis, caule brevi subsimplici sericeo-villoso, stipulis folio- 
lorum par infimum superantibus, foliolis coriaceis obovatis 
oblongisve emarginatis supra glaberrimis subtus sericeo-vil- 
losis margine valde incrassatis longe ciliatis. 
Arachis marginata, Gardn. Herb. Bras. n. 3103. 
Has. Rare in upland sandy Campos near the mission of Duro, 
province of Goyaz, Brazil. 
The specimen from which the figure has been taken is 
perhaps only the young state of a much larger plant, as all the 
other species of the genus have long, procumbent, lateral 
branches. It differs from A. villosa, Benth., by the leaves 
being smooth above; from A. tuberosa, Bong., by the long silky 
hairs which cover the whole plant, except the upper surfaces of 
the leaflets, and the much less reticulated foliage; and from 
both by this latter being more coriaceous and having a much 
thicker margin. My n. 2091, from Piauhy, is a broad-leaved 
form of Arachis pusilla, Benth, in Trans. Linn. Society, 18, p- 
159.—G. Gardner.
