Discussion:Dwyer (Bull. Torrey Club 72: 535, 536. 1945) assigned S. ramosissima Spruce ex Eichler to the Longifoliae and by inference selected a Riedel collection as the lectotype; he did not mention the two syntype Spruce collections cited in the original description. In describing S. minmta, Steyermark assigned the species, correctly we believe, to Dwyer's Linearifoliae, but did not note the affinities with S. ramosissima. Our six recent collections of S. miniata show no reliable vegetative distinctions from S. ramosissima; however the filaments are 0.2-0.4 mm long, the anthers 0.3-0.5 mm long, and the oval to rotund inner corona segments 0.7-1 X 0.5-0.7 mm. For the Riedel collection of S. ramosissima at New York, the corresponding measurements are 0.2 mm, 0.7-0.9 mm, and 1.1-1.4 X 0.5-0.55 mm, with the inner corona segments more oblong than in S. miniata and the anthers longer with relatively shorter filaments. Mr. Sandwith kindly examined the Kew material of Spruce 2497 and 3707, as well as Vie 7335 and 8227; he reported floral measurements consistent with S. miniata and also wrote that the Riedel collections of S. ramosissima at Kew have larger fruiting perianths and fruits than the Spruce and Ule sheets. The original description and plate of S. ramosissima offer no basis for upsetting Dwyer's lectotypification, so we believe it best, pending further Brazilian collections of S. ramosissima, to accept two very closely related species, with S. miniata being widespread north of the Amazon. The followina- material seems ascribable to S. miniata.
