Is perhaps a species of Bigelowia.

(not Linn.). 
As we understand that it was Rottler who usually named Heyne's plants 
for him, we should have expected this species to have been the same which 
we have referred above to S. hispida: we presume, however, that Mr Brown 
has ascertained the contrary. 
XXXI KNOXIA. Linn.; Gaertn. fr. t. 25 ; Lam. ill. t. 59. 
Calyx-tube ovate, somewhat ribbed : limb of 4 unequal minute teeth that 
are persistent and somewhat connivent when in fruit. Corolla hypocrateri- 
form or infundibuliform ; tube terete, usually bearded in the throat ; limb 4- 
lobed : sestivation valvular. Stamens 4, inserted upon the throat: filaments 
shortish or wanting: anthers-oblong. Stigma 2-lobed. Fruit 2-celled, com- 
posed of two indehiscent 1-seeded cocci: cocci either separating from each 
other from the base upwards, or falling off cohering together; the axis per- 
sistent and filiform (as the Umbellifere). Seeds ovate-triquetrous, erect. 
Albumen fleshy. Embryo erect.—Herbaceous or suffrutescent plants. Stems 
terete or 4-angled, erect. Leaves opposite, or apparently verticillated on ac- 
count of the fascicled axillary young ones. Stipules undivided or with se- 
veral bristles connecting the bases of the petioles. Cymes terminal, sessile or 
peduncled, the branches elongating in fruit and becoming spike-shaped. 
1351. (1) K. corymbosa (Willd. :) stem somewhat shrubby, erect, shortly 
villous or more or less hirsute, terete or obtusely 4-angled ; young shoots 
terete : leaves lanceolate, hispid on the upper side ; under pubescent, princi- 
pally so on the nerves: stipules with several long erect bristles : cymes co- 
rymbose, often very compound ; branches erect, at length spike-shaped : co- 
rolla infundibuliform ; tube slender, very villous on the inside: anthers in- 
cluded with the style exserted, or the filaments exserted with the style in- 
cluded : fruit oval, falling off entire —Willd. sp. 1. p. 582; Spr. syst. 1. p.

The same inverted proportion of stamens and style takes place in this plant, 
and also in K. Heyneana and K. Wightiana, which we have already noticed 
in several species of Hedyotis. We fear there are no good grounds for sepa- 
rating Dr Wallich’s K. Sumatrensis: Dr Wight's specimens of it, which he 
sent to Dr Wallich (Wall. L. n. 6183. b) were obtained from the Madras her- 
barium under the name of S. corymbosa, Willd. (so named by Willdenow 
himself), and are therefore identical with K. teres, Wall. L. n. 819. d. 
1352. (2) K. mollis (Brown:) stem shrubby, erect, obsoletely 4-sided, vil- 
lous ; branches 4-sided, villous: leaves lanceolate, pubescent : stipules with 
several bristles or subulate divisions: cymes corymbose, compound, ramifi- 
cations umbellate: corolla with a short tube: anthers included: fruit ob- - 
long, splitting from the base upwards.—Brown in Wall.! L. n. 820.—K. Su-
