23. Jacquemontia reclinata House, |. c., p. 435. 
Stem branched at the base or near it, the branches trailing or 
prostrate, mostly again branched, the foliage tomentulose, or the older 
leaves becoming glabrate: leaf-blades oblong to ovate-orbicular, 1—3 cm 
long, 0,5—2,5 cm broad, rounded or obtuse at the base, obtuse or retuse 
and mucronate at the apex, more or less densely tomentulose beneath, 
less so or glabrate above, the margins apparently never revolute; petioles 
2—10 mm long: peduncles exceeding the subtending petioles but not the 
blades, 1—5-flowered, the pedicels about as long as the peduncle: ealyx- 
lobes subequal, ovate, obtuse, 1,5—2 mm long: corolla white, rotate 
funnelform, 2,5—3 cm broad, 5-lobed, the lobes broadly ovate, obtuse: 
capsule globose, 4—5 mm in diameter, 4-seeded, 8-valved: seeds minutely 
scabrous with narrowly winged angles. 
Differs from Jacquemontia Jamaicensis (Jacq.) Hallier (Convolvulus Hava- 
nensis Griseb.), by its merely reclining stem and branches, its tomentulose 
foliage, broad leaf-blades which are not revolute, smaller calyx with 
broader and less acute lobes, the shorter and broader lobes of the corolla 
whieh are barely acute, and the globose capsule. 
Florida: The type-specimens were collected on Bull Key, opposite 
Lemon City, in XI, 1903 (Small & Carter, no. 630). Specimens referable 
to this species were collected at Palm Beach, in IV, 1897, by Mr. A. 
H. Curtiss (no. 5860). 
24. Heliotropium horizontale Small, l. c., p. 435. 
Perennial from a stout woody root, forming depressed mats: stem 
branched at the base, the branches prostrate, 1—4 cm long, commonly 
branched, strigose: leaves numerous, spreading; blades linear or nearly 
so, 8—16 mm long, acute, strigillose, short-petioled: racemes spike-like, 
many-flowered: calyx less strigose than the stem; lobes lanceolate, 
4—5 mm long, acute: corolla golden yellow; tube sparingly pubescent, 
about as long as the calyx; limb spreading, 7—9 mm broad: nutlets 
2 mm high. 
A species related to Heliotropium Leavenworthü Torr.: but with 
radiating prostrate branches, golden yellow corollas, larger calyx-lobes 
and larger nutlets. 
Florida: The type-specimens were collected in the pinelands between 
Cutler and Camp Longview, in XI, 1903 (Small & Carter, no. 742) 
Other specimens from the same region are as follows: Cocoanut Grove 
(Small & Nash, no. 175). Between Cocoanut Grove and Cutler (Small 
& Carter, no. 552). Between Cutler and Camp Longview (Small &
