1-2 axillary, and a terminal globose one, which is involucrated 
by reflexed bracteas; capsule oblong, villous at the apex, 
crowned by the 4 subulate, glabrous teeth of the calyx.—

50 B. Hanxea na (D.C. 1. c.) stem erect, sub-herbaceous,

flowers globose, terminal, girded by 4-leaved reflexed invo- 
lucra; capsule obovate, roughish, crowned by the 4 lanceo- 
late teeth of the calyx.—Native of Mexico and Peru. Bige- 
lowia psyllioides, Bartl. in herb. Henke. Spermacoce tenùior, 
Pav. ined. but not of Lin. It differs from B. psyllioides 
im the involucrum being reflexed, in the heads being one half 
larger, in the limb of the calyx being divided into 4 lobes to the 
base, not to the middle.

subulate teeth of the calyx.—Native of Brazil, where it was 
collected by Pohl. Spermacdce strictissima, Pohl, in litt. 
Allied to B. suavéolens, but differs from that species in the calyx 
being without accessory teeth. Corolla unknown.

margins, having a few oblique nerves on both sides ; bristles of 
the stipulas longer than the sheath, which is downy ; heads of

capsules oblong, hairy at top, crowned by the hairy 4-toothed

Var. B, angustifolia (D. C. prod. 4. p. 547.) plant weak ; 
leaves narrow-linear; heads size of peas; floral leaves spread- 
ing. h.S. Native of Brazil, where it was collected by Pohl;

pulas very long; heads of the flowers hemispherical, depressed, 
involucrated by 4 spreading leaves. h. S. Native of Brazil,

suffruticose at the base, erect; branches tetragonal; leaves 
linear, acutish, with revolute edges ; stipulas ending in 1-3 stiff, 
setaceous points; axillary heads few, or wanting, and 1 terminal 
and sub-globose, the latter involucrated by 2-4 reflexed floral 
leaves ; corolla glabrous ; capsule oval, glabrous, crowned by 
the 4 short teeth of the calyx. h.S. Native of Brazil, where

gonal, branched, scabrous from retrograde bristles; leaves linear- 
lanceolate, hairy on both surfaces, with -serrulately scabrous 
edges; bristles of stipulas longer than the sheath; heads of 
flowers terminal, involucrated by 6-8 radiant floral leaves ; calyx 
funnel-shaped, 4-cleft to the middle. h. S. Native of Mexico, 
near Ario. Fruit unknown, but from habit it is evidently a 
species of Borréria. Very nearly allied to B. strictissima and 
B. Henkeana. It differs from all the rest of the species in the 
calyx being divided to the middle. 
Fleawort-like Borreria. Shrub 1 to 2 feet. 
55 B. rtave'scens (D. C. prod. 4. p. 548.) plant diffuse, 
quite glabrous, suffruticose at the base ; branchlets tetragonal ; 
leaves oblong, acute, attenuated at the base; bristles of stipulas 
3-5, longer than the sheath; axillary whorles of flowers few, 
and one terminal and larger than the axillary ones, the latter in- 
volucrated by 2-4 floral leaves ; capsule oval, crowned by the 
lanceolate teeth of the calyx. h.S. Native of Brazil, where 
it was collected by Pohl. Spermacòce flavéscens, Pohl, in litt. 
The whole herb is yellowish. The nuts of the immature fruit 
appear almost indehiscent ; it is, therefore, perhaps a species 
of Diddia, with the habit of Borréria.
