312 MOXOCOTYLEDONES. 



herbs with bnlbs ; the inflorescence is terminal. In many species repro- 

 duction takes place by means of bulbils (small bulbs) formed in the axils of 

 the foliage-leaves (e.g. Lilittm bulbiferiim, htucifolium, etc., Gagea lancifolia, 

 etc.), or in the bracts of the inflorescence (many species of AUiitm) ; in many 

 species several buds are developed as bulbs in the axils of the bulb-scales them- 

 selves (accessory buds arising close together), and in some the formation of 

 buds is common on the leaves. 



A. TULIPEJ:, TULIP GROUP. Bulbs. The aerial, elongated stem 

 bears the foliage-leaves. Flowers few but generally large, with 

 free perianth-leaves. Tulipa ; style absent, no honey ; flowers 

 generally solitary, erect. Fritillaria perianth campanulate with 

 a round or oblong nectary at the base of each perianth-leaf. 

 Lilium; perianth widely open, generally turned back with a 

 covered nectary-groove in the centre of each segment. Anthers 

 versatile. -Lloydia ; Erythroiiium. 



B. HVACIXTHEJE, HYACINTH GKOUP. Bulbs. Leaves radical ; aerial 

 stem leafless with raceme or spike. In some the perianth-segments 

 are free, in others united. Honey is produced often in glands or 

 in the septa of the ovary (septal glands). Ornithogalum has a 

 leafy stem ; Scilla ; Eucomis has a tuft of floral-leaves above the 

 raceme; Agrapliis; Hyacinthus ; Puschkinia ; CMonodoxa; Muscari ; 

 Velfheimia ; Urginea. 



C. ALLIED, ONION GROUP. Generally bulbs. Leaves radical. 

 Stem leafless with a compound umbellate or capitate inflorescence 

 of unipared helicoid cymes, which before flowering are sur- 

 rounded by two broad involucral leaves. Allium. Filaments often 

 petaloid and bidentate ; iu many species bulbils are found in the inflorescence. 

 Some species have flat leaves: A. satirum, Garlic; A. pornun, Leek; A. 

 umiuum; others have round, hollosv leaves: A. cepa, Onion; A. fistulas um, 

 Winter Onion; A. ascalonicitm, Eschalot; A. scJuenoprasunt, Chive. Gagea ; 

 honey is secreted at the base of the perianth, no special nectary; 

 inflorescence few-flowered Agapanthus ; Tnteleia. 



D. ANTHEBICEJE. Rhizome; raceme; the leaves not fleshy and thick. 

 Anthericnm ; Aaphodelns ; Bulbine ; ChloropJnjtioii ; Jioicica has an almost leaf- 

 less stem with curved, climbing branches. 



E. ALOINE.E, ALOES. Stem generally aerial and tree like, bearing on its sum- 

 mit thick, fleshy leaves, often with a thorny edge (Fig. 306). Eacerne branched 

 or unbranched. Aloe ; Gasteria ; Yucca (has secondary thickening, p. 274). 



F. HEHEROCALLIDE.E. Phorwium, (Pli. tenax. New Zealand Flax) ; Fttnckia 

 (Hos(a); Hemcrocallis. 



At this point the following are best placed: Apliyllanthi-s (A. monspeliensia) ; 

 Xanthorrluea (Black-boy); Xerotes ; Lomandm ; Kingia ; the very membranous, 

 dry perianth of the last resembles that of the Juncacere, and also there are only 

 1-few ovules in the loculi.
