 thrive best in rich light soil, and are readily increased by cut- 

 tings or seeds.

Stiff" Freylinia. Shrub. 



Cult. Some of the species of this genus will survive in the 

 open ground against a wall with a south or west aspect, with a 

 little protection in winter. They will grow freely in any light 

 rich soil, or a mixture of turfy loam and peat ; and cuttings 

 strike root readily under a hand-glass.

 genus Halleria.) Link. Calyx small, S-4-lobed, unequal, per- 

 manent. Corolla large, funnel-shaped ; throat ventricose ; limb

 obtuse, and emarginate : the side ones shorter, broader, and 

 sharper : the lowest one very short, very slender, and very 

 sharp. Stamens 4, didynamous. Fruit baccate, roundish, 

 terminated by the style, 2-celled, many-seeded. Seeds flat, 

 roundish, winged. A shrub with opposite, serrated, shining 

 leaves. Pedicels axillary, aggregate.

 4 to 6 feet. 



2 H. ELLI'PTICA (Thunb. nov. act. ups. 6. p. 39.) leaves ob- 

 long, acute, toothed, cuneiform at the base, and quite entire ; 

 corollas equal ; calyx 4-lobed : stamens inclosed. ^ . G. Na- 

 tive of the Cape of Good Hope. H. lucida, ji, Lin. spec. 

 872. Burm. afr. 243. t. 89. f. 1 Corolla red, drooping. 

 Fruit oblong. " Leaves elliptic. Corollas truncate. Calyx 

 5-leaved." ex Thunb. 1. c. 



Elliptic-leaved Halleria. Fl. ? Clt. 1816. Shrub 4 to 6 

 feet. 



Cult. These shrubs may be treated like other hardy green- 

 house plants, by being housed with myrtles in the winter. A 

 light rich earth is the best for them ; and cuttings root readily 

 under a hand glass. They require to be exposed as much 

 as possible to the air, and to have plenty of water given to 

 them during summer. 



t Genera probably belonging to the order, b*t are not tuf- 

 ciently knoim. 



CVII. PI'KRIA (from -ucpoc, pitrot, bitter ; from the bitter- 

 ness of the plant.) Lour. coch. p. 393. Pers. encb. 2. p. 165. 



Lix. SYST. Didynamia, Angiospermia. Calyx 4-leaved, de- 

 ciduous, longer than the corolla ; alternate leaves linear, and 

 shorter. Corolla tubular, ringent, bilabiate; tube constricted 

 in the middle : upper lip spatulate, emarginate : lower lip larger 

 and trifid, with equal, roundish segments. Stamens 4, didyna- 

 mous ; the 2 longer filaments streaked by a papillose tube, and 

 bearing 1 -celled anthers, and the two shorter ones bearing 2- 

 celled, connected anthers. Berry ovate, 2-celled, many-seeded. 

 A very bitter, medicinal plant, with ovate serrated leaves, and 

 crowded flowers. 



1 P. FE'L-TE'RBLE (Lour. 1. c.) If. . ? G. Native of China 

 and Cochinchina. Stem tetragonal. 



Earth-gall Pikria. PI. 1| foot. 



Cult. For culture and propagation see Caslillejn, p. 616. 



CVIII. DIPLANTHE'RA (from &jrXooc, diploos, double; 

 and arQripa, anthera, an anther : in reference to the cells of the 

 anthers being distinct and diverging, therefore they appear 

 double.) R. Br. prod. p. 543. 



Lix. SYST. Didynamia, A ngiospermia. Calyx trifid ; upper 

 segment entire : lateral ones bifid. Corolla bilabiate ; throat 

 compressed ; upper lip obcordate : lower one tripartite, with 

 roundish lobes. Stamens 4, inserted in the bottom of the 

 corolla, exserted, nearly equal, ascending ; cells of anthers dis- 

 tinct, diverging, reflexed to the sides of the filaments in aesti- 

 vation. Ovarium 2-celled, many-seeded ; placentas 2, adnate 

 in each cell. Stigma bilamellate. Pericarp unknown. A mid- 

 dle-sized tree, with a diffuse, irregular tufted top. Branches 

 terete, tomentose. Leaves 4 in a whorl, large, petiolate, entire, 

 biglandular above the base. Thyrse terminal, roundish, de- 

 pressed. Partial peduncles verticillate ; pedicels trichotomous. 

 Flowers showy. Calyx half coloured. Corolla yellow. This 

 genus is probably nearer allied to Halleria than to any other.

 New Holland, within the tropic.
