Description:

Variety Description - As var. ernstii, but the leaves entirely glabrous, of thick texture, ± 7.5-10 cm long; sepals of staminate flower 8-8.5 mm long, 4.3-5.4 mm wide; petals ± 2.5 mm long, the appendage up to 0.6 mm long.

Disciphania clausa Diels, Pflanzenreich IV. 94: 176.1910. Type. “Para: Alto Purus, Porto Alegre, verblüht im April 1904, [female] blüh. und frucht. Mai 1908 (Huber in Herb. amaz. Mus. Para n. 4452 . . .)” (holotype, Huber 4452 in 1908, formerly at B, survives as Field Neg. No. 4999!). My concept of var. clausa is based principally on a staminate flowering plant (Ule 9383) at first identified in manuscript by Diels as a new species (“fulviflora”, nom. nud.), but in print (Notizbl. Bot. Gart. Berlin 6: 133. 1914) referred to his own D. clausa of which it was said to have the leaves. This judgment is borne out by study of the photograph of the pistillate holotypus of D. clausa. I found nothing in the flower of Ule 9383 by which D. clausa could be excluded from D. ernstii sens, lat., of which it appears to be little more than a fully glabrous phase occupying a segment of the Amazonian Hylaea intermediate between the ranges of var. glaziovii (pubescent and larger-leaved) to the south and var. uncinulata (with similar leaves but strongly pubescent) to the north. The type-locality was given erroneously as in Pará, this copied inadvertently from the head of the label (the location of Museu Goeldi); Ponte (not Porto) Alegre is a settlement on Rio Purus shortly above its confluence with Rio Acre near the Acre border in the state of Amazonas.
