=C.= ALLIEÆ, ONION GROUP. Generally bulbs. Leaves radical. Stem leafless with a compound umbellate or capitate inflorescence of unipared helicoid cymes, which before flowering are surrounded by two broad involucral leaves.--~_Allium._ Filaments often petaloid and bidentate; in many species bulbils are found in the inflorescence.--Some species have flat leaves: _A. sativum_, Garlic; _A. porrum_, Leek; _A. ursinum_; others have round, hollow leaves: _A. cepa_, Onion; _A. fistulosum_, Winter Onion; _A. ascalonicum_, Eschalot; _A. schænoprasum_, Chive.~--_Gagea_; honey is secreted at the base of the perianth, no special nectary; inflorescence few-flowered.--_Agapanthus; Triteleia._ =D.= ANTHERICEÆ. Rhizome; raceme; the leaves not fleshy and thick.--_Anthericum_; _Asphodelus_; _Bulbine_; _Chlorophytum_; _Bowiea_ has an almost leafless stem with curved, climbing branches. =E.= ALOINEÆ, ALOES. Stem generally aerial and tree-like, bearing on its summit thick, fleshy leaves, often with a thorny edge (Fig. 306). Raceme branched or unbranched.--_Aloë_; _Gasteria_; _Yucca_ (has secondary thickening, p. 274). =F.= HEMEROCALLIDEÆ. _Phormium_, (_Ph. tenax._ New Zealand Flax); _Funckia_ (_Hosta_); _Hemerocallis_. At this point the following are best placed: _Aphyllanthes_ (_A. monspeliensis_); _Xanthorrhæa_ (Black-boy); _Xerotes_; _Lomandra_; _Kingia_; the very membranous, dry perianth of the last resembles that of the Juncaceæ, and also there are only 1–few ovules in the loculi. POLLINATION by insects. Honey in some is produced on the perianth (see Tulipeæ), in others by glands on the carpels (in the septa and parietal placentæ, septal glands): _Hyacinthus_, _Allium_, _Anthericum_, _Asphodelus_, _Yucca_, _Funckia_, _Hemerocallis_, etc. Some _Allium_-species are protandrous. _Fritillaria_ is visited by bees, _Lilium martagon_ by moths, _L. bulbiferum_ by butterflies, _Phormium_ (New Zealand) by honey-birds.
