infl. Fir. g , usually regular, 5-merous, generally perigynous. Sta. 
in one whorl. Cpls. (3 — 2) each with 3 or 4 ovules, or 1 with 1 ovule. 
Capsule with 2, or nut with 1, seeds. Aril. Endosperm. Placed in 
Rosales by Benth. -Hooker. Rarely seen in Eur. [See Nat. 
Brunonia Sm. Goodeniaceae. 1 sp. Austr., Tasm. It differs from 
the other G. very much (see order) and is sometimes classed as a 
separate order. 
Brunsvigia Heist. Amaryllidaceae (1). 9 sp. S. Afr. 
Brya P. Br. Leguminosae (in. 7). 3 sp. Cent. Am., W. Ind. B. 
Ebenus DC. yields the wood known as Jamaica or American 
Ebony. 
Bryanthus S. G. Gmel. Ericaceae (1. 3). 6 sp. N. W. Am., one 
of which, B. taxifolius A. Gray, is circumpolar (incl. Brit.). 
Bryonia Linn. Cucurbitaceae (ill). 8 sp. Eur., As., Afr. B. dioica 
Jacq. is our common white bryony, which marks the N. limit of the 
order in Eur. The <? fir. is about twice as large as the ? . Honey is 
secreted at the base of the perianth and protected in the male by the 
bases of the filaments. The fir. is visited in Low Germany chiefly 
by short tongued bees, and especially by Andrena Jlorea F., which 
appears to confine itself to this plant (Muller). In Britain we have 
very few of these insects (in proportion), at any rate in the north and 
in Wales, and it is noteworthy that the bryony does not occur in 
Scotland and is rare in Wales. It would probably prove of interest 
to investigate its mechanism and insect-visitors in various parts of 
England. Being dioecious, it is dependent upon insects for fertili- 
sation, and it is possible that its distribution is largely determined by 
that of the insects suited to it (cf. Aconitum, Calystegia, &c.). 
Bryophyllum Salisb. Crassulaceae. 4 sp. S. Afr., Madag. B. caly- 
cinu?n Salisb. in Trop. of both worlds. In the notches on the leaves 
of this sp. adventitious buds develope, giving rise to new plants 
(p. 1 13). In B. proliferu?n Bowie there are simple and compound 
leaves on the same plant. Calyx and corolla are both gamophyllous. 
Buchanania Spreng. Anacardiaceae (1). 20 sp. trop. As. 
Buchnera Linn. Scrophulariaceae (ill. n). 30 sp. trop. 
Bucklandia R. Br. Hamamelidaceae. 1 sp. B. populnea R. Br. Himal. 
to Java. The large stipules are folded against one another, enclosing 
and protecting the young axillary bud or infl. The firs, are in heads, 
which stand in groups of 4. They are polygamous or monoecious 
and are sunk in the axis. The “calyx-tube” becomes visible as a 
ring after flowering. The wood is valued in the arts. 
Buda Adans. = Spergularia Presl. 
Buddleia Houst. Loganiaceae. 70 sp. trop. and sub-trop. This genus 
and its allies are sometimes placed in Scrophulariaceae, but possess 
stipules (though sometimes reduced to mere interpetiolar lines). 
Buettneria Loefl. Sterculiaceae. 50 sp. trop. 
Bulbine Linn. Liliaceae (ill). 24 sp. S. Afr.
