separated by an excessive enlargement of 

 the upper lip of the stigma. The true lip 

 is always divided to the very base into 

 thread-like lobes. The flowers appear to 

 be in all cases greenish, verging on yellow 

 or white. 



BONE-SEED. The common name for 

 Osteospermum. 



BONESET. Eupatorium perfoliatum; 



BONGARDIA. A genus of the berberry 

 family, but not at all like a berberry in 

 appearance. One species only (B. Bau- 

 wolfii) is known, and it is a small stemless 

 plant, with a tuberous underground root- 

 stock, somewhat like a small potato, from 

 the upper part of which spring four or five 

 long-stalked pinnatisect leaves. The flower 

 stalk is slightly branched and panicled, 

 and the flowers small, golden yellow, with 

 three to six calyx leaves, and six petals, 

 each of which has a little pit at its base, 

 like that of the buttercups. The genus 

 comes near to that of the lion-leaf (Leon- 

 tice), but differs in the pit at the base of 

 the petals, and in having a dilated stigma. 

 The plant is a native of Greece, Syria, and 

 Persia, extending to Afghanistan and 

 Scind. It was noticed as early as 1573 by 

 Rauwolf, who spoke of it as the true 

 Chr y sogonum of Dioscorides. The Per- 

 sians roast or boil the tubers, and use 

 them as an article of food, while the leaves 

 are eaten like sorrel. [A. A. B.] 



BONHOMME. (Pr.) Narcissus pseudo- 

 Narcissus ; also Verbascum thapsiforme, 

 BONNE DAME. (Fr.) Atriplex hortensis. 



BONNET D'ELECTEUR or DE PRE- 

 TRE. Cucurbita Melopepo ; also Euonymus 

 europceus. 



BONNAYA. A small genus of Scrophu- 

 lariaceo?, found in tropical and subtropical 

 Asia. They are annuals, usually glabrous, 

 with opposite leaves, and flowers in the 

 axils or in terminal racemes. The calyx 

 has five distinct narrow sepals ; the upper 

 lip of the corolla is erect and two-lobed, 

 the lower is larger, spreading and three- 

 lobed. The two upper stamens alone are 

 fertile, the lower pair, inserted at the base 

 of the lower lip of the corolla, are repre- 

 sented by the linear obtuse filaments. The 

 style is filiform with a dilated generally 

 two-lobed stigma. The linear capsule is 

 longer than the calyx. [W.C.] 



BONNETTA. A genus of the tea family 

 (TtrnstriimiacecE), composed of a few Bra- 

 zilian and Peruvian shrubs or small trees, 

 with sessile spathulate entire leaves, 

 having prominent parallel veins ; they are 

 generally crowded at the ends of the 

 branches, which are marked with promi- 

 nent scars where they have fallen. The 

 flowers are numerous and panicled, or 

 single, and as large as those of Camellia ; 

 generally white in colour, and composed of 

 a five-leaved calyx, five petals, a large 

 number of stamens, a three-parted style, 

 and a one-celled ovary, which becomes 

 when ripe a three-celled capsule containing 



many seeds. The leaves of B. paniculate, 

 a Peruvian species which attains the 

 height of twenty or thirty feet, have an 

 aromatic smell when bruised. [A. A. B.] 



BONPLANDIA. A genus of Butacece, 

 now generally merged in Galipea (which 

 see). [M. T. M.] , 



BONTIA. A genus pf Myoporacece, con- 

 taining a single species from the West 

 Indies. It is a small evergreen tree, in 

 habit so like the olive as to have been 

 named Olea sylvestris. The leaves are 

 alternate lanceolate and sub-entire, and the 

 flowers are solitary or in pairs on axillary 

 pedicels. The calyx is divided into five 

 ciliated imbricated lobes, two being ex- 

 terior. The corolla is tubular and bilabiate. 

 The four didynamous stamens are shorter 

 than the corolla. The ovoid ovary is two- 

 celled, each cell being almost divided by 

 an incomplete secondary septum ; there 

 are two ovules in each cell. The baccate 

 drupe has eight hard seeds. [W. C] 



BONUS HENRICUS. Good King Henry, 

 Ciienopodium Bonus Eenricus. 



BOOPIS. A genus of the Calycera 

 family comprising a few annual or peren- 

 nial herbs, some of them stemless and 

 with entire leaves, others branching with 

 pinnatisect leaves, and a habit not unlike 

 that of the chamomile. Their flower-heads 

 are stalked and terminal, containing many 

 white or yellow florets enclosed by a 

 membranous toothed involucre. The ge- 

 nus is readily distinguished from its allies 

 by the absence of spiny points to the calyx 

 leaves, and the nature of the involucre. The 

 species, eight in number, are found in the 

 Cordilleras of Chili, the neighbourhood of 

 Buenos Ayres, and also in the extreme 

 south of the continent. The generic 

 name is derived from the Greek bous, 

 an ox, and ops, an appearance ; the flowers 

 having somewhat the appearance of an 

 ox-eye. [A. A. B.] 



BOOREE. An Indian name for the 

 inflammable pollen of a species of 

 Typha. 



BOOR-TREE or BOUNTRT. A Scotch 

 name for the Elder, Sambucus nigra. 



BOOTIA. A genus of the natural order 

 Hydrocharidacece, found in the margin of 

 the river Irrawadi in Ava. The leaves are 

 all radical, some of them submersed, elon- 

 gate linear lanceolate, others cordate, float- 

 ing, with long petioles and a scape rising 

 out of the water ; flowers dioecious from 

 a tubular inflated spathe, which is toothed 

 at the apex, and includes many stalked 

 male flowers or a single sessile female one. 

 Perianth with three outer oblong calyx- 

 like divisions, and three inner oboA r ate 

 petaloid ones. As usual in the order, these 

 segments are in the female flower at the 

 top of a tube adhering to the ovary at the 

 base. Stamens twelve; ovary with nine 

 parietal placentas. [J. T. S.]

 species, is a small dioecious trailing shrub
