(holotype US 2342615). Paratypes. VENEZUELA, Terr. Amazonas. Cerro de 

 la Neblina: upper escarpment slopes east of Camp 3, alt. 1700 m, Maguire, 

 Wurdack, & Bunting 36841; escarpment west of Cumbre Camp, alt, 1700-1800 m, 

 Maguire, Wurdack, & Bunting 37091. 



L. maguirei would key to species 174-177 of Cogniaux' Monograph, but differs 

 from them in the harsher pubescence and 5-merous flowers. The glanduliferous 

 hairs of the Neblina endemic are somewhat obscured by the overtopping simple 

 setae. 



Leandra sanguinea Gleason subsp. tepuiensis Wurdack. subsp. nov. 



Calycis dentes exteriores ad anthesim 0.6-0.7 mm longi. Ovarii apex fere

Type: Shrub 1.5-3 m, inflorescence branches red-tinged, flowers white, fruit 

 reddish, frequent on escarpment slopes above Camp 3, Cerro de la Neblina, Terr. 

 Amazonas, Venezuela, elev. 1600-1700 m, 17 Nov 1957, Bassett Maguire, John J. 

 Wurdack, & Celia K. Maguirt 12030 (holotype US 2342601). Paratypes. VEN- 

 EZUELA, Edo. Bolivar. Cerro La Danta : fila between kms 125 and 127, alt. 

 1200 m, Steyermark d: Nilsson 184. Sororopan-tepui : summit, alt. 1800 m, 

 Maguire & Wurdack 33953. Chimanta Massif : waterfall course between north- 

 western part of Abacapa-tepui and Apacara-tepiu, alt. 1200-1600 m, Steyermark 

 7514.5; base of escarpment, Torono-tepui, alt. 1700 m, Steyermark 75488; slope 

 forest of main section between Apacara-tepui and Torono-tepui, alt. 1400-1700 m, 

 Steyermark 76000, Steyermark & Wurdack 1243; escarpment base, Amuri-tepui, 

 Steyermark & Wurdack 1335. Cerro Guaiquinima : slope forest near Intermediate 

 Camp, alt. 1200 m, Maguire 33106. 



The typical subspecies, known only from the Kaieteur Gorge, has subulate 

 external caJyx teeth 1.8 mm long and the ovary apex with a lobulate corona 

 tipped with numerous glandular hairs 0.3-0.5 mm long. An isotype of the Potaro 

 endemic (Sandwith 1268, NY) shows some gland-tipped hairs on the external 

 calyx teeth, as well as incurved-setose stem and inflorescence pubescence ; however 

 the topotypical Maguire & Fanshawe 23075 lacks glandular calyx hairs and has 

 appressed stem and inflorescence indument. In subsp. tepuiensis, there is similar 

 variability in the degree of hair appression ; there also is variability in the density 

 of the lower leaf surface hairs, some of the paratypes being sericeous-strigose 

 but with no concomitant floral differentiation.
