Authority: Maguire, Bassett & Wurdack, John J. 1961. The botany of the Guayana Highland--part IV (2). Mem. New York Bot. Gard. 10: 1-87.
Description:Latin Diagnosis - Habitus robustior; sepalorum setae parce minores; capsulae maiores.

Distribution and Ecology - VENEZUELA: Amazonas: frequent in Sabana Hechimoni, Cano Hechimoni 8 km above mouth, Rio Siapa, alt. 120 m; shrub to 5 dm tall, petals pink basally white, stamens deep rose; 9 Feb 1954, Maguire, Wurdack & Bunting 37625 (holotype, NY). Savannas at northwest base of Cerro Yapacana, alt. 125 m, Maguire, Cowan & Wurdack 30567, Maguire & Wurdack 34508, Maguire, Wurdack & Keith 41533 (paratypes). COLOMBIA: Cacagual savanna, Rio Atabapo, alt. 125 m, Maguire, Wurdack & Keith 41457 (paratype).

Discussion:The typical subspecies is up to 15 cm tall, with capsules 4-5.5 mm long and sepals terminated by a seta 1-2 mm long. In subsp. venezuelensis, the plants are (25-)35-50 cm tall, the capsules 6-7 mm long, and the sepalar setae 0.5 mm long; generally also the petals are larger, 6-6.5 m m long rather than 3-4.5 mm. The seeds of the two subspecies are alike (0.7 X 0.4 mm) and both subspecies show the same coronal structure. We have not seen the Spruce Venezuelan collection (3513, from the mouth of the Rio Guainia) cited by Dwyer (Bull. Torrey Club 72; 538. 1945) for S. linearifolia; otherwise, the typical subspecies seems limited to Minas Gerais and Goias in Brazil. The Venezuelan subspecies in general aspect is reminiscent of S. sprengelii St.-Hil.
