BROMELIACEAE 
2 . Pitcairnieae (capsule; ovary semi-inf. or almost sup.; leaf 
entire, or toothed at base, rarely at top) : Pitcairnia. 
3. Puyeae (capsule; ovary sup.; leaf thorny; usually large 
stem) : Puya, Dyckia. 
4. Tillandsieae (do., but leaf entire; seed hairy): Tillandsia. 
[Placed in Epigynae by Benth. -Hooker, in Liliiflorae by Eichler 
(Warming).] 
Bromus Dill. Gramineae (x). 45 sp. temp., and trop. Mts. 7 in 
Brit, (brome-grass). Though so common, they are of no value as 
pasture grasses. 
Brcsimum Sw. Moraceae (11). 8 sp. trop. Am. The infl. is remark- 
able (fig. in Nat. P/t.), consisting of a spherical pseudo-head com- 
posed of one ? fir. and many S firs. The former is sunk into the 
centre of the common receptacle, and its style projects at the top, 
whilst the latter occupy the whole of the outer surface. Each S fir. 
has a rudimentary perianth and one sta., whose versatile anther 
dehisces in a curious way, passing from a shape somewhat like T to 
one like f . The achene is embedded in the fleshy receptacle. 
The achene of B . Alicastrum Sw. is the bread-nut (not to be con- 
fused with Artocarpus, the bread-fruit), which is cooked and eaten in 
the W. Ind., &c. B. Galactodendron D. Don. is the cow-tree or 
milk-tree of Venezuela. When a notch is cut in the stem, the milky 
latex flows out in considerable quantities ; it tastes very like ordinary 
milk and is used for the same purposes. The wood of several sp. is 
useful, though liable to split. 
Broussonetia L’Herit. Moraceae (1). 3 sp. E. As. Dioecious; S firs, 
in pseudo-racemes, with explosive sta. like those of Urtica (unusual 
in this order) ; ? firs, in pseudo-heads. Multiple frt. (cf. Morus &c.). 
B. papyrifera Vent, is the Paper-mulberry of Japan. Paper is 
made from the inner bark (see Treas. o/Bot.) ; in Polynes. the natives 
make cloth from it (tapa or kapa cloth). 
Browallia Linn. Solanaceae (v). 6 sp. trop. Am. 
Brownea Jacq. [Hermesias Loefl.). Leguminosae (11. 3). ro sp. trop. 
Am., W. Ind. The young shoots hang down and their leaves are 
red (p. 157). The firs, in some sp. are borne on old wood (p. 156). 
Bruckenthalia Reichb. Ericaceae (iv. 9). 1 sp. S. E. Eur. 
Brugmansia Blume. Rafhesiaceae. 3 sp. Malay Arch. 
do. Pers. = Datura Linn. 
Bruguiera Lam. Rhizophoraceae. 5 sp. trop. As., Afr., Austr. One 
of the trees of the mangrove-formation (p. 19 1). Like Rhizophora 
but without the aerial roots from the higher branches. The roots in 
the mud give off erect aerating branches, as in Sonneratia &c. 
Brunella Tourn. = Prunella Linn. 
Brunfelsia Plum. Solanaceae (v). 22 sp. trop. Am. 
Bruniaceae. Dicotyledons (Archichl. Rosales). 12 gen. with 50 sp. 
Cape Col. Heath-like shrubs, with alt., exstip. leaves and racemose
