MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 



[VOL. 10 



VENEZUELA: Amazonas: Cerro de la Neblina, occasional under upper escarpment, 

 cliffs above Camp III, alt. 1800 m; shrub 1-2 m high, inflorescence maroon, petals pink, yellow 

 at base; 24 Dec 1953, Maguire, Wurdaclc $ Bunting 36837 (holotype, NY); Cerro de la 

 Neblina, in 1953, Maguire, Wurdaclc 4' Bunting 36846, 36922, 36954; in 1957, Maguire, 

 Wurdaclc 4- Maguire 42042, 42426 (para types). 



Adenarake muriculata superficially resembles Adenanthe bicarpellata in the 

 somewhat similar glandular calyx, and Lavradea in general habit. It is obviously 

 closely related to neither, but has more probably developed along an independent 

 evolutionary line. The cyclic calyx, conspicuous androgynophore, and septicidal 

 capsule, valvate above and completely (3-) septate at the base, are unique in 

 the tribe. 



Sauvagesia L. Sp. PL 1:203. 1753. 



Sauvagesia erioclada Maguire & Phelps var. grandiflora Maguire & Wurdack, 

 var. nov. 



A var. erioclada differt noribus maioribus. 



VENEZUELA: Amazonas: Cerro Yuta.je, frequent in thickets in scrub forest on North- 

 west Ridge, alt. 1400 m; slender virgate shrub 1-3 m tall, petals white, corona purple; 11 Feb 

 1953, Maguire $ Maguire 35151 (holotype, NY). 



S. erioclada var. erioclada lias sepals -i. 1-6.1 mm long, the inner corona 2.8-4 

 mm long, and anthers 1.8-2.2 mm long. In var. grandiflora the sepals are 8-10 

 mm long, the inner corona 4.8-5 mm long, and the anthers 2.5-2.6 mm. All 

 measurements were taken on dry fruiting material. The leaf variability range in 

 recent collections of S. erioclada is quite great, but the leaves are always thinly 

 coriaceous to coriaceous with acute to broadly acute apices. The collections of 

 var. erioclada now include: Cerro Yutaje, Maguire ((• Maguin 35101, 35300, 

 35313, 35332; Cerro Coro-Coro, Maguire & Maguire 35467 1 Cerro Moriche, 

 Maguire A Maguire 35538, Maguire, Cowan & Wurdack 30839, 30871, 30896, 

 30920: Cerro Guanay, Maguire, Phelps, Hitchcock d- Budowski 31659, 31796. 



Sauvagesia duidae Steyermark. 



Since both 8. duidae and S. grandifolia Dwyer have similar chartaceous 

 acuminate leaf blades, the only apparent valid morphologic distinction between 

 these two species is in the flower size. In S. duidae, the fruiting sepals (dry) 

 are 4.2-5.6 mm long, the inner corona 3.6-3.9 mm, and the anthers 1.8-2.2 mm. 

 In the Brazilian species, the corresponding measurements (dry) are 9.1-9.5 mm, 

 ca. 7.5 mm, and 2.3-2.5 mm. In Venezuela, in addition to the type collection, 

 8. duidae is known from the Yapacana savanna edge at 125 m alt. (Maguire <& 

 Wurdack 34521) ; for Colombia the species is known from two Amazonas collec- 

 tions: Rio Miritiparana, alt. 200 m, Schultes & Cabrera 15704 (US); Rio 

 Popeyaca, alt. 200 m, Schultes & Cabrera 16183 (US). For S. grandifolia, only 

 the holotype (Glaziou 6478, US) is known to us. With some qualms, the follow- 

 ing key to this species group is offered : 



1. Leaves acuminate, chartaceous. . 



2. Sepals 4.2-5.6 mm long; inner corona 3.6-3.9 mm high. S. duidae. 



2. Sepals 9.1-9.5 mm long; inner corona ca. 7.5 mm high. S. grandifolia. 

 1. Leaves acute (sometimes apiculate but not acuminate), coriaceous to chartaceous. 



3. Shrubs with erect woody stems; leaves thinly coriaceous to coriaceous; fruiting 



calyx corneous at the base. S. erioclada. 



3. Herbs or usually sprawling subshrubs; leaves chartaceous; fruiting calyx not 



thickened basally. S. erecta.
