long; panicle axillary, 14 in. long, all hirto-puberulous, on a peduncle 3 lines long, fur- 
nished above with 6-8 subsecund alternate flowers, on pedicels 2 lines long, each sup- 
ported by a setiform puberulous bract 3 lines long; sepals acute, puberulous, 1 line long, 
terminated by a setiform appendage of the same length. The corolla had fallen away ; 
but another was seen in an extremely young state covered with dense ferruginous 
tomentum.

several alternate flowers on filiform pedicels 9 lines long ; sepals ovate-lanceolate, 1 line 
long; corolla dark-red; tube cylindrical, contracted below the middle, 10 lines long; 
segments obliquely obtuse, undulate on the margins, dextrorsely convolute, 4 lines long; 
stamens inserted above the base of the tube; anthers linear, acuminate, with 2 subacute

SECONDATIA. 
This genus was established by Prof. A. De Candolle in 1844, and afterwards illustrated 
by Prof. Müller in the ‘ Flora Brasiliensis.’ It consists of a few slender scandent species, 
the branches minutely crenulate across the nodes, with extremely small intrapetiolar 
stipules, opposite petiolate leaves, and a terminal, very short raceme, furnished with 
few very inconspicuous flowers on a short divided peduncle. The fruit is peculiar in 
shape, consisting of 2 suberect follicles, broad and fusiform, woody, containing many 
seeds, with a long elastic coma of numerous spreading hairs, recurving outwards in a 
trumpet-form.
