Type. Silva secundaria no inundabili, loco arenoso humedo, Entrancamento, Belem, Para, Brazil, 14 May 1946, A. Ducke 1953.

The var paraensis differs in the spreading or long pubescence of the stem, otherwise like var amazonica with quaternate, sessile leaves which are sulcate-nerved above and abruptly acuminate at apex.

Some differences are to be noted between the specimens examined of Spruce 992, the first specimen cited by Schumann, and Spruce 1353. In the latter collection the leaves are not prominently sulcate above on the nerves as in Spruce 992, and, furthermore, they are shorter, being 23-25 × 4.2-6 cm. Further, the stipules of Spruce 1353 are shorter, only 2.5 × 0.8 cm. In the Spruce 992 sheet the inflorescence is 45 cm long, but only 26-30 cm long in Spruce 1353. In the Spruce 1353 specimen no lower branches of the inflorescence are observable at anthesis, whereas in Spruce 992 a pair of short lateral branches 3 cm long are visible. In the Spruce 1353 specimen the calyx lobes are short, broadly triangular, with apiculate tips, and 0.2-0.3 mm long, whereas in Spruce 992 the calyx lobes are more slender and nearly linear, and 0.5-0.9 mm long.

The Ducke 194 and Krukoff 7967 collections resemble closely the Spruce 1353 specimen.

Remijia amazonica Schumann has a habit similar to that of R. ulei Krause, but the leaves are sessile or nearly so, conspicuously sulcate-nerved above with the nerves closer together and the tertiary venation beneath less prominent and less elevated, the calyx lobes and tube are shorter as are also the hypanthium and corolla, the leaves are quaternate, the capsules are shorter, and the stipules are more lanceolate and with longer acuminate tips.
