220 ON SOTJTH-AMEEICAN APOCTNACE^. 



revolute margins, having above immersed, almost evanescent nerves, beneath pmictulate- 

 scabrid, with short sparse soft hairs, 3-4 in. long, 1^-2 in. broad, on thick petioles 4 lines 

 long ; raceme lateral, shorter than the leaves ; peduncle thick, stiff, glabrous, bearing 

 many densely crowded smallish flowers, on pedicels viscidly puberulous, nearly 9 lines 

 long, thickened above ; sepals obtusely ovate, scarcely 1 line long, altogether with about 

 8 minute internal scales ; tube of corolla narrowly cylindrical for half its length, 8 lines 

 long, a little swollen above ; segments obliquely ovate, 4 lines long ; ovaries enclosed 

 within an urceolate disk of 5 truncated subconnate lobes.

 Serra de Araripe (Gardner 1756). 



A twining shrub, with slender flexuose branchlets, lenticellate and ferruginously sub- 

 hirsute; leaves elliptic or lanceolately oblong, obtuse at the base, shortly acuminate, 

 rigidly membranaceous, dark green, opake, and glabrous above, paler and hirsute be- 

 neath, with darker nerves, 2-3^ in. long, 10-20 lines broad, on petioles 3 lines long ; 

 raceme lateral, on a slender peduncle 6-8 Hnes long, with many minute caducous 

 bractlets ; flowers on twisted, slender, puberulous pedicels ; sepals lanceolate, acuminate, 

 2f lines long, unequal, puberulous, with membranaceous ciliate margins ; corolla 10^ 

 lines long ; tube longer than the sepals, pubescent, funnel-shaped above, contracted near 

 the middle, and there staminigerous ; segments sparsely pubescent on both sides, with 

 white margins, half as long as the tube ; disk urceolate, margin shortly cleft into 5 fleshy 

 lobes, half as long as the 2 ovaries. 



7. MiTozus TENELLTjs, nob. : Odontadenia angustifolia, A. DC. I. c. p. 360. In Guiana GaUica : non 



A. climbing glabrous plant, not to be confounded with the Echites rnigustifolia of Ben- 

 tham or with that of Poiret. Leaves oblong-lanceolate, obtuse and subcordate at the 

 base, very acute, 4 in. long, J-f in. broad, on petioles 6 lines long ; panicle lateral, 

 nearly 4 in. long, on a dichotomously divided peduncle, bearing many flowers on re- 

 flexed pedicels 6 lines long ; sepals obovate-oblong, 2 lines long ; tube of corolla 9 lines 

 long, lower part pUose within and staminigerous in the middle ; disk urceolate, of 5 

 fleshy truncate lobes, unequally connate, a little shorter than the 2 ovaries. 



It certainly does not belong to Odontadenia ; it is a species apparently very close to 

 the preceding.

 (Gardner 3517) . 



A subscandent plant, with very slender striate branches, the axils 2J-3 in. apart ; 

 opposite leaves Unear-oblong, shortly cordate at the base, subacute and mucronate at the 

 summit, with revolute margins, rigidly coriaceous, sulcate above along the middle, convex 

 on each side of the midrib, pale green above, sparsely and softly pubescent, with about 

 12 pairs of patent arcuate immersed nerves, pale yellow and pruinosely velutinous be-
