Macairea aspera, N. E. Brown, sp. n. (Plate 2.) Folia oblonga, ohtusa, supra scaberrima, 

 subtus appresse rufo-toinentosa. Calyx appresse pubescens et glandulosus. Petala 

 obovato-oblonga, obtussisima. glauduloso-ciliata. Staminum filamenta superne 

 glandulosa. Ovarium superne dense glandulosum, stylo parce glanduloso. 

 A branching shrub; elotbed on the young shoots, branches of the panicle, pedicels 

 and calyx with rather long, rust-coloured, adpressed hairs. Leaves opposite; 

 petiole 4-6 lin. long, pubescent like the stems ; blade 1|~ 3 in. long, 8-17 lin. broad, 

 oblong, obtuse, or shortly and stoutly apiculate, cuneately rounded into the petiole 

 at the base, coriaceous, 3-nerved, with the lateral nerves close to the revolute margin, 

 scabrid with minute, conical, hair-tipped tubercles on the upper surface, tomentose 

 beneath with a dense adpressed pubescence of rust-coloured hairs. Panicles 4-6 in. 

 long, 2-3| in. broad, many-flowered. Pedicels 1-2| lin. long, minutely bibracteolate in 

 the middle. Calyx with sessile glands mingled with the hairs outside ; tube campanulate. 

 H lin. long ; lobes \h lin. long, deltoid, acuminate. Petals 3-4 lin. long, 2^-3 lin. broad,

Upper slopes of Mount Roraima, McConnell A' Quelch, 31. 



Another specimen (no. 24, McConnell 8f Quelch), collected at the same place as no. 31. 

 is identical with it in all particulars excepting the anthers, in which the portion of the 

 connective between the pollen-cells and the dilated base is very much longer than in 31,
