\ 



differentiated, or solitary and terminal. Pedicel 4-9 mm. below the bracteoles, 1-5 

 mm. above; pedicellar bracteoles 3.5*5 x 2-4 mm., rarely leaflike to 11 x 6 mm., 

 elliptic, above glabrous or apically strigulose, below as the leaves, early cadu- 

 cous or persistent until just after anthesis. Hypanthium 4-8 x 4-6 mm., 0.4-0.7 

 mm. thick medianly, very densely strigulose to short-strigose 15-30/mm. 2 Sepals 

 (4-)5-7 x 3-4.5 mm., ovate-oblong with the apices obtuse to rounded, united at 

 bases 0.4-1.2 mm., the sinuses narrowly acute or rounded, sometimes with a few 

 longer sinal hairs to 1-2 mm. Petals pale yellow, 9-17 x 9-15 mm., asymmetri- 

 cally obovate with the apices obliquely truncate to very broadly obtuse, the cilia 

 0.1-0.5 mm. (terminally to 0.6-1 mm.) and non-glandular (rarely a few of the basal 

 cilia with early-caducous glandular tips). Filaments 5-9.5 mm.; anthers 4-9 mm.; 

 connective at anther base 0.5-0.8 mm. wide but almost always not at all prolonged 

 nor free of the anther. Style 17-25 x 0.5-0.8 mm., exserted 2-8 mm. Ovary 5-7.5 x 

 3-4.5 mm., sparsely strigulose on the apical 1.5-3 mm., the apical lobes 0.5-1.5 

 mm. above the locules. 



Type Collection and Locality: /. de Jussieu s.n. (HOLOTYPE presumably in 

 Herb, de Jussieu at P). Since de Jussieu began his Andean collecting in northern 

 Ecuador and visited Quito, the type locality is probably somewhere in this area, 

 perhaps the slopes of Pichincha which are readily accessible from Quito and from 

 which subsequently have been collected many specimens which duplicate the type 

 photograph. 



Type Photographs and Illustrations: F36131 (presumed holotype); F36136 (pre- 

 sumed holotype of Rhexia canescens at P); F36130 (presumed holotype of Chae- 

 togastra sulphurea at P);F36l29 (presumed holotype of Chaetogastra bonplandiana 

 at P); Rhexies pi. 6, not pi. 2 8(1806-1808) (as Rhexia canescens)-, Ann. Sci. Nat. 

 III. 14: pi. 4, f. 6 (as Chaetogastra bonplandiana); Trans. Linn. Soc. 28: pi. 3, f. 

 33e (as Brachyotum sulphureum. The assignment of this name and drawing to B. 

 ledifolium is questionable, since the flower shown is 4-merous and the anthers mi- 

 nutely tuberculate.)
