Barklya F. Muell. Leguminosae (in. 1). 1 sp. Queensland. 
Barleria Linn. Acanthaceae (iv. A). 100 sp. trop. largely on steppes. 
The bracteoles are frequently represented by thorns. The seeds have 
surface hairs which swell when wetted and help to anchor them to 
suitable places for germination (p. 106). 
Bamadesia Mutis. Compositae (xn). 12 sp. S. Am. Shrubs. 
Barosma Willd. Rutaceae (iv). 15 sp. S. Afr. 
Barringtonia Forst. Lecythidaceae. 30 sp. E. Afr. to Samoa. The 
wood of some sp. is useful and the seeds yield oil, used for lamps. 
Bartholina R. Br. Orchidaceae (3). 1 sp. S. Afr. 
Bartonia Muhl. Gentianaceae (1. 2). 3 sp. N. Am. Saprophytes 
with a little chlorophyll and leaves reduced to scales. 
Bartonia Sims. (Loasaceae) = Mentzelia Linn. 
Bartramia Linn. =Triumfetta Linn. 
Bartsia Linn. (incl. Odontites Hall.). Scrophulariaceae (ill. 12). 60 sp. 
N. temp., trop. Mts., and S. Am. B. Odontites Huds. and 2 others, 
in Brit. Mostly herbs, semi-parasitic (on grass-roots, see order). Fir. 
with loose-pollen mechanism (see order). 
Basella (Rheede) Linn. Basellaceae. 1 sp. trop. As. A climbing herb 
whose firs, remain closed. The fruit is enclosed in the perianth. 
Basellaceae. Dicotyledons (Archichl. Centrospermae). A small family 
united with Chenopodiaceae by Benth. -Hooker and Warming, but 
differing in their internal anatomy as well as in morphology. They 
possess an underground rhizome or tuber, giving off annually a 
climbing shoot, often with fleshy leaves, and racemes or panicles 
of firs. These are stalked and often conspicuously coloured. Each 
has 2 bracteoles, 2 sepals, and 5 petals. Opposite these are 5 sta. 
Ovary superior, of 3 cpls., with terminal style and 3 stigmas, uni- 
locular. Ovule 1, basal, campylotropous. Fruit usually a berry. 
Chief genera : Basella, Ullucus, Boussingaultia. 
Baskervilla Lindl. Orchidaceae (4). 1 sp. Peru. 
Bassia All. = Anisacantha R. Br. (Chenopodiaceae). 
Bassia Koenig ex Linn. ( Illipe F. Muell.). Sapotaceae (1). 30 sp. 
Indo-mal. &c. B. pallida Burck yields a gutta-percha. The seeds 
of B. bntyracea Roxb. (Indian butter tree) yield a butter-like substance, 
used for soap-making &c. The firs, of B. latifolia Roxb., the mahua, 
mahwa, or mowa, are edible, and the wood useful. 
Bassovia Aubl. Solanaceae (11). 12 sp. Cent, and S. Am. 
Bastardia H. B. et K. Malvaceae (11). 2 sp. W. Ind. and S. Am. 
Batatas Choisy=Ipomaea Linn. ( B . edulis Choisy = I. Batatas). 
Batemannia Lindl. Orchidaceae (18). 1 sp. Brit. Guiana. 
Batidaceae ( Batideae , Bentham- Hooker). Dicotyledons (Archichl. 
Centrospermae). Only genus Batis (q.v.). See Nat. PJl . Placed 
in Curvembryae by Benth. -Hooker and Warming. 
Batis Linn. Batidaceae. 1 (or more?) sp., coasts N. Am.
