A well-marked species, with very large leaves, whicli are unequal at the base, rigidly- 

 coriaceous, margins recurved, above fuscous green, op^ke, minutely corrugulated, with 

 convex interspaces between the sulcate patently divergent nerves arcuately con- 

 joined near the margin, beneath opake ochreous, with very prominent thick reddish 

 midrib and nerves, 8|-11| in. long, 3:|— 5^ in. broad, on thick petioles only 2 lines long, 

 deeply channelled, with a hooded elevated margiu, deeply fossate at the base, and 

 connected across the node by a transverse ridge. Panicle short, erect, lateral at the 

 node, on an obsoletely pubescent stoutish peduncle 9 lines long, very shortly and rather 

 closely branched, each branch bearing 2-3 flowers on stoutish pedicels 1^ line long, 

 supported by a shorter ovate bract ciliolated on the margin; sepals rounded ovate, 

 distinct, 1 line long, with an inner basal 6 -fid scale ; tube of corolla (in bud) 7 lines long, 

 cylindrical, suddenly narrowed in the middle ; segments of the border rhomboidally dola- 

 briform, 3 lines long, stnistrorsely convoluted ; stamens inserted in the contraction of 

 the tube, on a retrorsely pilose ring ; anthers, disk, style, and clavuncle as in the generic 

 character. FoUicles gibbously oval, 1 in. long, 5 lines broad, with a thickly coriaceous 

 pericarp, densely echinated as in JBeschiera, dehiscing along the convex ventral suture ; 

 seeds not numerous, oblong, somewhat pointed at the apex, 5 lines long, 2J lines broad, 

 longitudiaally striated with several asperulous lines, subcompressed, channelled on the 

 ventral face, where they are attached to a pallid fleshy funicle. 



A representation of this species, and an analysis of its flower, fruit, and seed are 

 shown in Plate IX. a. 



CODONEMMA*. 



This genus is proposed for a few plants from the Rio Negro and Guiana, the type of 

 which is the Taberncemontana calycina of Spruce {T. Benthamiana bis of Muller). They 

 are distinguished by their large leaves and their inflorescence, the chief peculiarity of 

 which consists in a large campanular calyx, cleft halfway down into 5 oblong imbricated 

 divisions, the fleshy tubular portion being furnished within with numerous lanceolate 

 scales, arranged in several series. 



CoDONEMMA, nob. : Calyx majusculus, tubuloso-campanulatus, superne ad medium in lobos 5 subacutos, 

 oblongo-lanceolatos, margmemembranaceos, erectos, subinsequales fissus, intus basin versus squamulis 



* From Kciauv (eampana), ^ixfta {vestisX on account of its bell-sliaped calyx.
