Description:
Species Description - Small tree, dichotomously branched, the branchlets terete, densely grayish lepidote when young, with a few large pale lenticels. Leaves 1-3(-5)-foliolate, often incompletely divided, the leaflets of compound leaves elliptic, rounded at base, rounded to acutish at apex, to 13 x 6 cm, the unifoliolate leaflets ovate, truncate to somewhat cordate at base, rounded to acutish at apex, 4-12 cm long, 3-7 cm wide, very densely whitish lepidote below, less so above, discolorous, brownish or olive above, gray to whitish below, also minutely and inconspicuously puberulous with simple trichomes along main veins below, the margin entire; petioles 1-5.5 cm long. Flowers and fruits unknown.

Discussion:
This species is known only from sterile collections and is not very different from the T. bibracteolata complex with which it shares white leaf undersurfaces and the distinctive presence of simple trichomes (presumably from the stalks of stalked-peltate scales) along the main veins below. Since the ecology is quite different (coastal limestone vs. upland serpentine), I do not feel that T. polymorpha should be subsumed under even a sensu lato T. bibracteolata without additional collections.
