AMARYLLIS 
Amaryllis Linn. Amaryllidaceae (i). i sp. A. belladonna L., 
Cape Colony. The flr. is rendered zygomorphic by the upward 
curve of the sta. ; the style projects above the anthers, favouring 
cross-pollination. 
Amasonia Linn. Verbenaceae (ii). 6 sp. trop. Am. 
Ambora Juss. = Tambourissa Sonn. 
Ambrosia Linn. Compositae (v). 15 sp., 1 Medit., 14 Am. Heads 
unisexual, the ? one-flowered. Fruit enclosed in the involucre. 
Ambrosinia Linn. Araceae (vn). 1 sp. Medit. 
Amelanchier Medic. Rosaceae (11. 4). 10 sp. N. temp. 
Amellus Linn. Compositae (11 1). 9 sp. S. Afr. 
Amentaceae = orders in cohorts 3, 7, 8, of Archichlamydeae. 
Amethystea Linn. Labiatae (1. 1). 1 sp. Siberia. 
Amherstia Wall. Leguminosae (11. 3). 1 sp., A. nobilis W all. (India), 
remarkable for its splendid firs. Stalk and bracts as well as petals are 
bright pink. Sta. united in a tube. Young shoots pendulous (p. 157). 
Amianthium A. Gray = Zygadenus Michx. 
Amicia H. B. et K. Leguminosae (ill. 7). 5 sp. Andes. In A. Zygo - 
meris DC. the big stipules protect the bud. 
Ammannia (Houst.) Linn. Lythraceae. 18 sp., wet places, cosmop. 
Amini (Tourn.) Linn. Umbelliferae (5). 6 sp. Old World. 
Ammobium R. Br. Compositae (iv). 2 sp. New S. Wales. A. alatum 
R. Br. is often cultivated for its flower-heads, which, when dried, form 
one of the many “everlastings.” 
Ammpphila Host. Gramineae (vm). 1 sp. N. temp. (incl. Brit.), 
A. ( Psamma ) arundinacea Host., common on sandy coasts (marram 
grass). It is largely used to bind sand dunes, possessing a long 
rhizome. After some years a light soil is formed in which fescue 
and other plants take root, and gradually the whole is covered with 
vegetation. The leaves curl up inwards in dry air, thus avoiding 
transpiration (see order). [See p. 186.] 
Amomum Linn. Zingiberaceae. 50 sp. trop. As., Afr., Austr., 
Polynes. The leafy stems rarely bear flrs. ; these are borne on other 
axes springing directly from the rhizome. Many sp. furnish forms of 
Cardamoms. See Elettaria. 
Amorpha Linn. Leguminosae (ill. 6). 10 sp. N. Am. A. fruticosa 
L. is common in shrubberies. The small flrs. are arranged in a 
dense spike. Wings and keel are absent, the standard only remain- 
ing; it folds round the stamen-tube at the base. The flr. is 
protogynous with persistent stigma. 
Amorphophallus Blume. Araceae (iv). 15 sp. E. Ind. There 
is a corm-like rhizome, giving rise yearly to one enormous leaf 
(in some sp. the stalk 15 feet long and the leaf 10 feet across) 
and an equally gigantic infl. (in A. Titanum Becc. 3 feet high) 
with <? flrs. above and ? below. Its dirty red and yellow colour, 
and foetid smell, attract numbers of carrion flies by which it
