Var. y, corymbosa (Blum, mss.) cymes branched, on long 

 peduncles, disposed in somewhat fastigiate corymbs. Tj . S. 

 Native of Java. Perhaps a proper species. 



Wood Cianitis. Shrub 2 to 3 feet. 



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

 plants ; and cuttings will root readily in the same kind of soil, 

 under a hand-glass. 



XVIII. ADA^MIA (in honour of John Adam, some time 

 Governor-General of India ; a promoter of natural history). 

 Wall. tent. fl. nep. p. 4C. t. 36. D. C. prod. 4. p. 16. 



LIN. SYST. Decdndria, Pentagynia. Tube of calyx adnate to 

 the ovarium ; limb with 5 short teeth, having the recesses between 

 the teeth broad and obtuse. Petals 5, alternating with the teeth 

 of the calyx, surrounding the top of the ovarium. Stamens 10. 

 Styles 5, ending in rather clavate, somewhat 2-lobed stigmas. 

 Berry crowned by the limb of the calyx, somewhat 5-celled, 

 many seeded. Embryo terete, straight, in a fleshy albumen, 

 with the radicle turned towards the hilum. A smooth branched 

 shrub. Leaves opposite, exstipulate, petiolate, oblong-lanceo- 

 late, serrated. Panicle corymbose, terminal, many flowered. 

 Flowers bluish. Berries blue. Perhaps not distinct from 

 Cianitis. 



1 A. CYAN^'A (Wall. 1. c.) T? . G. Native of Nipaul, in 

 rocky places, on mountains near the Great Valley, where it is 

 called Bansook by the natives. Hook. bot. mag. t. 3046. Wall. 

 pi. rar. asiat. 3. t. 213. 



.Bfee-berried Adamia. Fl. June, July. Clt. 1829. Shrub 

 4 to 6 feet. 



Cult. See Cianitis above for culture and propagation. 



XIX. BROUSSArSIA (in honour of the celebrated M. 

 Broussais, M.D. author of physiological medicine). Gaud, in 

 Freyc. voy. t. 69. D. C. prod. 4. p. 17. 



LIN. SYST. Decdndria, Monogynia. Calyx 5-parted, hemis- 

 pherical, distinct from the ovarium : lobes ovate-deltoid, blunt- 

 ish, equal. Petals oblong, acuminated, with a reflexed point 

 (nearly as in umbelliferous plants) twice the length of the calyx, 

 valvate in aestivation. Stamens 10, hypogynous, surrounding 

 the base of the ovarium ; filaments subulate, distinct ; anthers 

 ovate. Ovarium roundish, crowned by the short style and trun- 

 cate stigma, 5-celled ; cells many seeded. A shrub, with op- 

 posite oval petiolate sharply serrated leaves, and corymbs of 

 fertile flowers. The shrub has the habit of Hydrangea, but 

 differs in the ovarium being distinct from the calyx, in the style 

 being short and solitary, not 2-3, and in the fruit being 5- 

 celled. 



1 B. ARGU'TA (Gaud. 1. c.) Tj . G. Native of the Sandwich 

 Islands, at the altitude of from 1200 to 1500 feet above the level 

 of the sea. A middle-sized tree. 



SAarp-serrated-leaved Broussaisia. Tree. 



Cult. See Cianitis above for culture and propagation.

Calyx with the tube adhering to the ovarium (f. 55. F. h. f. 

 55. C. e.) ; limb 5-toothed (f. 55. F. e.), or entire (f. 55. G.f.) : 

 lobes or teeth deciduous or permanent. Petals 5 (f. 57. c. f. 

 59. g.), inserted in the top of the tube of the calyx, and altern- 

 ating with its lobes, either entire (f. 57. c.), emarginate (f. 61. 

 >.), or 2-lobed, sometimes plain at the apex, but usually drawn 

 out into a replicate or involute point (f. 6 1 ./. f. 63. e. f. 55.C.L), 

 somewhat imbricate in aestivation, rarely valvate ; the outer 

 flowers of the umbel or ray of the umbel sometimes larger than 

 the rest, the rest equal among themselves, rarely abortive. 

 Stamens 5 (f. 55. C. b. &c.), alternating with the petals, and 

 inserted along with them, and therefore opposite the calycine 

 teeth or lobes, always distinct, replicate in aestivation (f. 59. g. 

 &c.) ; anthers ovate, 2-celled, somewhat didymous, opening by 

 a double longitudinal chink. Ovarium inferior, 2-celled (f. 55. 



E. c. f. 55. D. d. &c.), (very rarely, and probably from abor- 

 tion, 1 -celled), adnate to the calyx ; styles 2, distinct (f. 55. 



F. i. f. 55. G. i. f. 59. e. &c.), when young erect, but at length 

 thickened at the base into stylopodium(f. 64. a.), which covers the 

 whole disk, forming a sort of crown to the fruit, diverging more 

 or less, usually permanent, the outer one directed to the outside 

 of the umbel, and the inner one tending to the centre. 

 Fruit (called Diachce'na, Polachce'na, and Cremocarp by many 

 botanists) consisting of 2 carpella (called mericarps because 

 (f. 55. D. d. f. 56. C. h. &c.) they adhere to the calyx 

 the half of their length, and therefore cannot be carpella or 

 achenia in the strict sense of those terms), separable from a 

 common axis (called a carpophore), to which (f. 56. G. a. 

 f. 56. C. a. b. &c.) they adhere by their face (called the com- 

 missure) ; the fruit or cremocarp traversed by 10 elevated pri- 

 mary ridges, of which the 5 that represent the middle of the 

 sepals are called carinal, because they are drawn out into caly- 

 cine teeth at the apex : the other 5, alternating with the first- 

 named ones are called sutural, because they indicate the sutures 

 where the divisions of the calyx are joined, and therefore tend 

 to the recesses between the calycine teeth ; besides these there 

 are others which are apparent in some called secondary, because 

 they alternate with the 1 primary nerves, and therefore indicate 

 the sides of the divisions of the calyx ; all the sutural, carinal, 

 and secondary ribs are either filiform, winged, or crested ; 

 these ridges or nerves are separated by channels or furrows 

 called valleculae, below which, but usually in the channels, 

 are placed in the substance of the pericarp, certain linear recep- 

 tacles of coloured oily matter, called vittee, which are directed 

 from the apex to the base : they are solitary, twin, or numerous, 

 rarely wanting, and sometimes they are inclosed in a proper 

 membrane, which is probably a true pericarp. Seeds solitary in 

 each carpel, hanging from the top of the axis or carpophore, 

 inclosed in a proper membrane, the spermaderm, which is 

 but rarely separable from the pericarp. Albumen large, 

 fleshy, or rather horny, more or less convex on the out-
