MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 



[VOL. 10 



Sauvagesia miniata Steyermark. 



Dwyer (Bull. Torrey Club 72: 535, 536. 1945) assigned 8. ramosissima 

 Spruce ex Eiehler to the Longifoliac and by inference selected a Riedel collec- 

 tion as the lectotype; he did not mention the two syntype Spruce collections 

 cited in the original description. In describing 8. miniata, Steyermark assigned 

 the species, correctly we believe, to Dwyer 's Linearifoliae, but did not note the 

 affinities with 8. ramosissima. Our six recent collections of 8. miniata show no 

 reliable vegetative distinctions from 8. 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 8. 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. Sand- 

 with kindly examined the Kew material of Spruce 2497 and 3707, as well as 

 Vie 7335 and 8227 ; he reported floral measurements consistent with 8. miniata 

 and also wrote that the Riedel collections of 8. ramosissima at Kew have larger 

 fruiting perianths and fruits than the Spruce and Ule sheets. The original 

 description and plate of 8. ramosissima offer no basis for upsetting Dwyer 's 

 lectotypification, so we believe it best, pending further Brazilian collections of 

 8. fam&sissima, to accept two very closely related species, with 8. miniata being 

 widespread north of the Amazon. The following material seems ascribable to 

 8. miniata. 



VENEZUELA: Bolivar: Isla Casabe, Bio Paragua, Maguire 32710; slopes of Cerro 

 Bolivar, Maguire, Wurdack 4' Bunting 35954 ; base of Piedra Marimare, Rio Orinoco, Wurdack 

 4" Monachino 40869. Amazonas: Puerto Ayacucho, Maguire, Wurdack 4' Bunting 36184; 

 Eaiulal de Atures, Maguire, Wurdack 4' Bunting 36120 ; Cano Cupueni near San Fernando de 

 Atabapo, Maguire, Wurdack 4' Bunting 36231; Sanariapo, Steyermark 58467 (isotype NY); 

 Esmeralda Ridge, Steyermark 57730 (fide Steyermark). 



BRAZIL: Terr. Rio Braneo: Serra Tepequem. Maguire 4' Maguire 40013; Serra.de 

 Carauma, Ule 7735 (K) ; Serra do Mel, Ule 8227 (K, US). Amazonas: Panure, Spruce 2497 

 (K) ; mouth of Rio I§ana, Baldwin 3228 (US). 



Sauvagesia linearifolia St.-Hil. subsp. venezuelensis Maguire & Wurdack, 

 subsp. nov. 



Habitus robustior; sepalorum setae parce minores; capsulae maiores. 



VENEZUELA: Amazonas: frequent in Sabana Hechimoni, Cano Heehimoni 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 4" Bunting 37625 (holotype, NY). Savannas at northwest base 

 of Cerro Yapacana, alt. 125 m, Maguire, Cowan 4' Wurdack 30567, Maguire 4' Wurdack 34508, 

 Maguire, Wurdack 4~ Keith 41533 (paratypes). 



COLOMBIA: Cacagual savanna, Rio Atabapo, alt. 125 m, Maguire, Wurdack 4" Keith 

 41457 (paratype). 



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 mm 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 8. linearifolia; otherwise, the typical subspecies seems limited 

 to Minas Gerais and Goias in Brazil. The Venezuelan subspecies in general 

 aspect is reminiscent of 8. sprengelii St.-Hil.
