is one of the most elegant hardy shrubs yet introduced to our 

 gardens, as it produces its beautiful scarlet flowers the greater 

 part of the year. It is a very proper plant for training against a 

 wall. All the species may be increased by ripened cuttings off 

 the roots, planted in a sheltered situation, with a hand-glass 

 placed over them. They are also to be increased by grafting 

 the one on the other, or on any of the plants contained in the 

 present order. 



t Genera doubtful whether they belong to the present order. 



XII. DICA'LYX (from fie, dis, double, and Ka\v, kalyx, 

 a calyx ; so named in consequence of the calyx being calycu- 

 lated by bracteas, which assume the appearance of an outer 

 calyx.) Lour. coch. p. 663. Blume, bijdr. 1116. Decadia, Lour.

 acuminated, acute at the base, finely serrulated above the middle, 

 smooth, rather pubescent on the veins beneath ; spikes panicled,

6 D. SALACE'NSIS (Blum, bijdr. 1118.) leaves elliptic-oblong, 

 acute at both ends, finely serrulated, and are, as well as the 

 branches, quite glabrous ; spikes simple or branched, axillary 

 and terminal, short, densely tomentose. ^ S. Native of Java, 

 on Mount Salak. Flowers white.

7 D. SESSILIFOLIUS (Blum, bijdr. 1118.) leaves nearly sessile, 

 oval, acute at both ends, finely serrulated, and are, as well as 

 the branches, glabrous ; spikes branched, axillary and terminal, 



rather tomentose ; fruit smooth. T^ . S. Native of Java, on 

 the top of Mount Cede. Flowers white.

8 D. SPICA'TUS (Blum, bijdr. 1118.) leaves lanceolate, acumi- 

 nated at both ends, quite entire or serrulated, and are, as well as 

 the branches, glabrous ; spikes axillary and terminal, simple or 

 branched, clothed with silky tomentum ; fruit ovate, glabrous.

9 D. CILIA'TUS (Blum, bijdr. 1119.) leaves oblong-lanceolate, 

 acuminated at both ends, nearly entire, and are, as well as the 

 branches, glabrous ; spikes branched, axillary, downy ; bracteas 

 and calyxes ciliated ; fruit oval, smooth ; calycine segments

 ceolate, acuminated at both ends, finely serrulated at the apex, 

 and are glabrous as well as the branches ; panicles axillary or 

 almost terminal, smooth. Ij . S. Native of Java, on Mount

 but the leaves are acuminated, and the serratures hardly con- 

 spicuous.

 white.

Cult. A mixture of loam, peat, and sand will suit the species 

 of this genus, and ripened cuttings will probably root if planted 

 in sand, with a hand-glass placed over them. 



XIII. PYRENA'RIA (from pyren, a cherry-stone ; in re- 

 ference to the bony seeds). Blum, bijdr. 1119.

 what adnate to the base of the petals. Anthers bursting out- 

 wardly. Ovary 5-celled ; cells biovulate. Styles 5, ap- 

 proximate, emarginate. Pome globose, depressed, fleshy, 5- 

 celled ; cells covered with a papery membrane, containing 

 each two bony seeds. Seeds exalbuminous. Embryo erect, 

 with leafy contortuplicate cotyledons. This genus has the habit 

 of Pomacece, but from the structure of the calyx and insertion 

 of the stamens it comes nearer to Ternslrcemiacece.

 alternate, stalked, oblong, serrated, coriaceous, exstipulate 

 leaves ; axillary solitary 1 -flowered peduncles, and white flowers.
