herb, meo (n. 4026, ia flore et fructu) montibus Organensibus. 



A scandent shrubby species, with glabrous, fuscous, trichotomous patent branches 

 and slender branchlets, all verruculous with crowded raised yellow lenticels, the axils 

 f in. apart ; leaves elliptic, obtuse or subacute at the base, contracted at the summit 

 iuto a subobtuse acumen, flaccidly chartaceous, glabrous, opake green above, with 6 

 pairs of fine diverging nerves and retictdated veins, paler beneath, with prominulent 

 yellow nerves, 1^2J in. long, |-1 in., broad, on slender glabrous petioles 2 lines long ; 

 racemose panicles at the end of the young branchlets, about as long as the leaves, 

 covered with yellow tomentum ; peduncle terete, lenticellate, bearing several opposite 

 patent or refracted branchlets at intervals of ^ in.., and about 6 lines long, each with 

 very short secondary branchlets beariag several approximate almost sessile flowers ; 

 petals obtusely ovate, ^ line long ; corolla 2 lines long, its tube J line long ; segments 

 linear -oblong, puberulous outside, with rigid villous hairs inside, expanded and re- 

 flexed at the apex ; stamens upon short filaments inserted within the tube ; anthers as 

 long as the tube, wholly exserted, their membranaceous summits connivent at the trun- 

 cate apex, coriaceous and shortly bilobed at the base, all glabrous ; style slender, short ; 

 clavuncle thick, club-shaped ; stigmata short, terete, terminal ; follicles 2, pendent, free 

 torose, striolate-sulcate, acute, 10-13 in. long, the seminiferous lobes fusiform, 5 lines 

 long, 2 lines thick, alternating with as many strangulations ^-f line thick, 8 to 12 lines 

 long, glabrous, fuscous; seeds linear-oblong, 5 Hues long, crowned by a persistent 

 rufescent, sericeous, very spreading coma 9 lines long, 



A drawing of this species, in flower and in fruit, is shown in Plate XXXV. b.

This plant agrees with Claussen' s, as described by MiiUer, ia the shape of its 

 leaves and its inflorescence ; only the leaves are somewhat smaller ; the branches are 

 glabrous, fuscous, the younger ones paler and puberulous ; leaves ovate-lanceolate, 

 obtuse or subcordate at the base, gradually and acutely acuminate, submembranaceous, 

 dark green above, opake, of a rufescent hue, younger ones subpubescent, 1^2^ in. long, 

 4-7 lines broad, on slender petioles 2^-3 lines long (in Claussen's plant the leaves are 

 2^3f in. long, 11-12 liaes broad, on petioles 2 lines long) ; raceme terminal, 2^3 ia. 

 long, narrowly subpyramidal, with many patent or subrefracted branchlets again closely 

 divided, bearing very numerous minute flowers on very short slender pedicels ; sepals 

 extremely minute, puberulous ; coroUa pubescent, | line long, tube extremely short. 



The plant bears no resemblance to the F. meridionalis of Miiller, as stated by him ; 

 it comes nearer to his F. Riedelii.
