flourish in the open air, many of them 

 turn yellow and lose their leaves in a 

 very short time if taken into a dwelling- 

 room, especially if placed in dark corners 

 and where gas is used. Such plants, 

 however, soon recover if replanted out 

 of doors. 



Y. aloifolia. — A native of the West 

 Indies, N. Carolina &e., having slender 

 stems 15-20 ft. high, and tufts of green 

 glaucous-tinted leaves 12-18 in. long, 

 tipped with a reddish-brown spine, and 

 having whitish serrulate edges. Flowers 

 in May and June, white, about 2 in. deep, 

 in dense rhomboid panicles 1-2 ft. long. 

 There are numerous forms of this 

 in cultivation, the best known being 

 Athinsi and xiurpurea, with purplish 

 foliage; arcuata, crenulata, and tenui- 

 foUa, with narrow leaves ; conspioua and 

 Draconis, with broader recurved leaves ; 

 quadricolor and tricolor, leaves variously 

 edged with green, red, and yellow; and 

 variegata, striped with creamy-white. 



Culture dc. as above. This species is 

 hardy in the milder parts of the country, 

 and will stand several degrees of frost 

 without injury in some gardens, while 

 in others a few degrees will affect it. 



Y. angustifolia. — An almost stemless 

 species about 3 ft. high, native of Missouri 

 &c., and producing dense masses of stiff 

 linear leaves l|-2 ft. long, ehanneUed 

 above, sharply pointed, and frayed into 

 numerous reddish-brown threads on the 

 margins. Flowers in summer, greenish- 

 white, 2-3 in. deep, in racemes about 

 1 ft. long, on the top of a simple erect 

 scape 8-4 ft. long. A good rock plant. 

 The variety striata has broader and less 

 rigid leaves, and a looser panicle of 

 flowers, y. hanhuryana is allied to this 

 species. It has hneaj? rigid green leaves 

 with brownish edges, and simple racemes 

 about 1^ ft. long of white bell-shaped 

 flowers. 



Culture do. as above. 



Y. constricta {Y. albo-spioa). — This 

 species extends from Utah to N. Mexico, 

 and has simple stems 3-5 ft. high, with 

 dense clusters of stiff linear channelled 

 leaves 1^2 ft. long, strongly pointed, and 

 having the reddish margins very much 

 frayed into threads. The white flowers, 

 about 2 in. deep, appear in summer in a 

 deltoid panicle 3-4 ft. long, the ascending 

 branches being 6-9 in. long. 



Culture (fc. as above. 



Y. filamentosa (Silk Orass). —An 

 attractive and almost stemless species 

 from N. America with dense rosettes of 

 firm sword-shaped leaves li-2 ft. long, 

 and about 2 in. broad, having a somewhat 

 glaucous tint, and the white edges frayed 

 into thread-like filaments. The white 

 flowers tinted with green outside are 

 borne on scapes 5-8 ft. high in June, in 

 dense rhomboid panicles with ascending 

 flexuous branches. There are many 

 varieties of this species, including golden - 

 striped and silver-striped ones which a,re 

 very attractive, but not so hardy as the 

 green-leaved type. The plant known as 

 Y. flaccicLa is only a variety of filamen- 

 tosa, but is distinguished by having less 

 rigid and more recurving leaves than the 

 type, and downy panicles of white flowers 

 with broader segments. Y. glaucescens 

 is another variety distinguished by its 

 glaucous leaves about 1 in. wide, and 

 its flower stems densely covered with a 

 bluish-grey down. 



Culture do. as above. 



Y. glauca. — An ornamental North 

 American species without stems, having 

 tufts of sword-like leaves li ft. long and 

 about 1| in. broad, glaucous when young, 

 stiffly pointed, and edged with red-brown, 

 the margins being entire or slightly 

 frayed. The white broadly bell-shaped 

 flowers appear in summer in dense 

 pyramidal panicles 2-3 ft. long, well above 

 the foliage. 



Culture do. as above. 



Y. gloriosa (Mound Lily). — A native 

 of the United States, having, when old, 

 more or less branched stems 4-6 ft. or 

 more high. The stiff erect slightly 

 glaucous-green leaves, l^-S ft. long and 

 2-3 in. broad, are in dense rosettes, 

 strongly pointed, and margined with 

 reddish-brown, or serrulate in a young 

 state. Its white or greenish-white bell- 

 shaped flowers, tinged with red outside, 

 are borne in summer in dense rhomboid 

 panicles 4-6 ft. long, and give the plant a 

 really glorious appearance. 



There are many varieties of this, the 

 best and hardiest being recurvifolia, 

 which is also well known as recurva 

 and pendula. The beautiful somewhat 

 glaucous leaves are gracefully recurving, 

 and make it a handsome plant for lawns, 

 vases &o. When it gets old a stem is 

 .developed with huge tufts of leaves and 

 immense trusses of flowers. It will not
