Pin~
Root biennial (?), fibrous, the fibres thickish, somewhat
downy, simple.
L eaves all springing from the root, ovate, horizontal,
arranged in a stellate form, with the margin rolled
in, yellowish, scattered above with raised

Corolla of one petal, within beautifully veined, having
white hairs, the margins undulated, two-lipped,
the upper lip (which by the curvature of the
scape appears the lower one) is three-lobed, the
