ANACARD1UM 
Anacardium Linn. Anacardiaceae (i). 8 sp. trop. Am. A. occu 
dentale L. is the Cashew-nut, largely cultivated. Its stem yields 
a gum. The firs, are polygamous. Each has one cpl. which 
yields a kidney- shaped nut with a hard testa containing a black acrid 
juice. The nut is edible if the testa be carefully removed. Under it 
the axis of the fir. swells up into a large pear-like body, fleshy 
and edible, and so the seeds are distributed by animal agency. 
Anacharis Rich. = Elodea Michx. 
Anacyclus Linn. Compositae (vn). 12 sp. Medit. 
Anagallis (Tourn.) Linn. Primulaceae (in). 12 sp. Eur., As., Afr., 
S. Am. 2 sp. in Brit., the pimpernels. A . arvensis L. is often 
called ‘poor man’s weather-glass,’ because the firs, close in dull 
or cold weather. 
Anagyris Linn. Leguminosae (in. 2). 2 sp. Medit. 
Anamirta Colebr. Menispermaceae. 7 sp. Indo-malaya. The 
achenes of A . Cocculus Wight et Am. are known as “Cocculus indi- 
cus” and are sometimes used to adulterate porter, &c. though they 
contain an irritant poison. In the angles between the big veins of 
the leaves are acaro-domatia covered with hairs (see p. 115). 
Ananas Tourn. Bromeliaceae (1). 6 sp. trop. Am.; of these the 
best known is A . sativus Schult., the Pine-apple. The stem is short 
(terrestrial) and leafy, bearing a terminal infl. of a mass of firs, in 
the axils of bracts. These, together with the axis and the fruits, 
form a general fleshy mass after fertilisation, and the main axis 
usually goes on beyond it and produces more green leaves — the ‘crown’ 
of the pine-apple. Seeds are rarely formed. [See Treas . of Bot.] 
Anaphalis DC. Compositae (iv). 30 sp. Eur., As. 
Anastatica Linn. Cruciferae (iv. 18). 1 sp., A. hierochuntina L., 
the Rose of Jericho. This plant inhabits the regions from Syria 
to Algeria, where a long dry season occurs every year. While 
the seeds are ripening the leaves fall off and the branches fold 
inwards until the whole is reduced to a dry ball of wicker-work. In 
this state it is easily loosened from the dry ground and it may be 
blown bodily along by the wind, the fruits remaining closed. If it be 
driven into water or on to wet soil, or in any case when the wet 
season comes on, the hygroscopic nature of the twigs causes their 
unfolding, and at the same time the capsules open and shed their 
seeds. [See pp. no, 168.] 
Anaxagorea St Hil. Anonaceae (3). 20 sp. trop. As., Am. 
Anchusa Linn. Boraginaceae (iv. 3). 40 sp. Old World. A. officinalis 
L. was formerly officinal and is widely scattered, occurring as an 
escape in Brit. 
Ancistrocladaceae. Dicotyledons (Archichl. Parietales). Only genus 
Ancistrocladus (y.z>.). The order is united with Dipterocarpaceae by 
Bentham and Hooker, but separated by Gilg (in Nat . Pfl . 1894), 
on the ground of the 1 -locular ovary, endosperm, &c.
