CLXXV. JA'CKIA (named in memory of the late William 

 Jack, a surgeon in the service of the East India Company, whose

LIN. SYST. Pentdndria, Monogynia. Limb of calyx uni- 

 lateral, trifid. Corolla funnel-shaped, with a filiform tube, and a 

 campanulate 5-cleft border; segments lanceolate, valvate in 

 aestivation. Anthers filiform, sessile in the throat of the corolla, 

 semi-exserted. Style long, hairy in the middle ; stigma 2-lobed. 

 Capsule? crowned by 3 large unilateral wings, 1 -celled, and 

 1 -seeded? Tree tall. Leaves large, opposite, on short petioles, 

 clliptic-obovate, cuspidate, clothed with rusty hairs beneath, as 

 well as the branches, which are obscurely quadrangular. Stipulas 

 combined, sheathing, fringed, interpetiolar. Panicles large, axil- 

 lary, opposite, pendulous, on very long peduncles, hairy, and 

 villous, with spreading opposite slender branches, each termi- 

 nated by a corymb of crowded subdichotomous spikes. Pedun- 

 cles slender, compressed, partial ones each supported by a pair 

 of ample fringed connate bracteas, which sometimes grow out at 

 the margins into opposite small floral leaves. Flowers white, 

 inodorous, sessile, alternate, disposed in short unilateral spikes, 

 and each flower is supported by an oval densely villous toothed 

 permanent bractea, and these bracteas are somewhat imbricated 

 on the back of the spikes.

SUBTRIBE II. CEFHJELI'DEK (the plants contained in this sub- 

 tribe agree with the genus Cephce'lis in the flowers being dis- 

 posed in involucrated heads). D. C. prod. 4. p. 532. Cephae- 

 lidese, Cham, et Schlecht. in Linnsea. 4. p. 133. Flowers dis- 

 posed in fasciculate heads ; the heads involucrated by bracteas.

LIN. gYST. Pentdndria, Monogynia. Calyx with an obovate 



tube, and a very short 5-toothed limb. Corolla funnel-shaped, 

 with 5 small bluntish lobes. Anthers inclosed. Stigma bifid, 

 usually exserted. Berries obovate, oblong, 2-celled, 2-seeded, 

 crowned by the vestiges of the calyx. Shrubs and herbs, natives 

 of America. Leaves ovate, acute, petiolate. Stipulas twin on 

 both sides, free or combined, and sometimes bidentate or bipar- 

 tite. Heads of flowers terminal or axillary, sessile or peduncu- 

 late, involucrated by 2-8 bracteas, which are disposed in a cru- 

 ciately opposite manner ; there are also bracteoles or paleae 

 among the flowers. Perhaps the species with dry berries, and 

 those with fleshy berries, ought to be separated into distinct 

 genera. Perhaps E~vea is properly joined with this genus, not- 

 withstanding its tetrandrous flowers. Probably Carapichea 

 might be joined with this genus, but for its exserted stamens. 



SECT. I. TAPOGOMEA (Tapogomo is the Guiana name of the 

 first species). D. C. prod. 4. p. 533. Heads of flowers invo- 

 lucrated by 2 large spreading connate coloured bracteas. 



1 C. TOMENTOSA (Willd. spec. 1. p. 977.) branches, petioles, 

 peduncles, leaves, and involucra hairy ; stipulas acuminated, 

 villous ; heads of flowers on long peduncles ; leaves of involu- 

 crum broad, ovate-cordate, wide at the apex. Jj . S. Native of 

 Guiana, Trinidad, and probably of Mexico (if C. cyanocarpa, 

 Moc. et Sesse, fl. mex. icon. ined. be the same,) in open spaces 

 of woods, and about way sides. Tapogomea tomentosa, Aubl. 

 guian. 1. p. 160. t. 61. Cephae'leis tomentosa, Vahl, eclog. I. p. 

 19. Callicocca tomentosa, Gmel. syst. 1. p. 371. Peduncles 

 axillary and terminal. Bracteas or involucrum scarlet, or of a ver- 

 milion-colour, large, sometimes long-acuminated, and sometimes 

 only cuspidate. Branches obscurely tetragonal. Berries striated, 

 ex Aubl., but blue and smooth according to the fig. in fl. mex. 

 There are therefore 2 species probably confused. In Trinidad 

 we have seen this shrub growing in great abundance, and where 

 it makes a very elegant appearance from its scarlet bracteas ; 

 the flowers, as far as we can remember, are brownish, and the 

 berries bluish.

 punicea, Poir. diet. 7. p. 585. Leaves oblong or elliptic, acu- 

 minated at both ends, 3-5 inches long. Branches reddish. Pe- 

 tioles villous at the base while young. Stipulas twin on both

 lets, furrowed, reddish. Leaves of involucrum scarlet, cordate, 

 ovate.

 peduncles ; leaves of involucrum obtuse, hardly equal in length 

 to the heads. J; . S. Native of the south of Jamaica, on the 

 high mountains ; and of Guadeloupe. Callicocca elaia, Gmel. 

 syst. 1. p. 372. Tapogomea elata, Poir. diet. 7. p. 585.

 cave, purplish red. Paleae among the flowers small, stiff, and

4 C. RUELU.EFOLIA (Cham, et Schlecht. in Linnaea. 4. p. 134.)
