BROWNLOWIA 275 
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, ex Linn. Gramineae (x). 60 sp. temp., and trop. Mts. 
7 in Brit, (brome-grass). Though so common, they are of little or 
no value as pasture grasses. 
Brongniartia H. B. et Iv. Leguminosae (ill. 6). 20 sp. trop. Am. 
Brosimum Sw. Moraceae (11). 10 sp. trop. Am. The infl. is remark- 
able (fig. in Nat . Pfl>), 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 <? 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 ?. The achene is embedded in the fleshy receptacle. 
The achene of B. Alicasirum 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. [The bread-nut of Barbados is, however, a seeded 
var. of the bread-fruit.] 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. 
Broughtonia R. Br. (incl. in Epidendrum in Nat. Pfl>). Orchidaceae 
(13). 2 sp. W. Ind. 
Broussonetia L’Herit. Moraceae (1). 3 sp. E. As., Polynes. Dioecious; 
S firs, in pseudo-racemes with explosive sta. like those of Urtica 
(unusual in this order) ; ? firs, in pseudo-heads. Multiple fruit 
(cf. Morus, &c.). B. papyrifera Vent, is the paper-mulberry of 
Japan. A good fibre, used for paper, &c., is obtained from the 
inner bark ; in Polynes. the natives make tapa or kapa cloth from 
it. The leaves double upwards during the heat of the day. 
Browallia Linn. Solanaceae (v). 6 sp. trop. Am. 
Brownea Jacq. (Hermesias Loefl.). Leguminosae (11. 3). 10 sp. trop. 
Am., W. Ind. The young shoots emerge very rapidly from the bud 
and hang downwards on flaccid stalks, the leaflets at first rolled up, 
and later spread out, and pink or red speckled with white. After 
a time they turn green and stiffen up and spread out in the normal 
position. The plant being a shade-loving tree, like Amherstia, which 
behaves in the same way, this phenomenon is supposed to be pro- 
tective. B. grandiceps Jacq. and others have fine bunches of flowers. 
Brownlowia Roxb. Tiliaceae. 1 sp. Indo-mal.
