usually brown margin at first with a very few distant rarely persistent 
minute teeth, when developed entire or occasionally with a few detach- 
ing slender fibers. Inflorescence mostly narrowly paniculate, the base 
often not exserted, glabrous or exceptionally puberulent. Flowers 
creamy white, often tinged with red or violet: ovary often with a slight 
suggestion of basal stipe; style oblong, white, frequently 3-divided. 
Fruit obovoid-oblong, mostly pendent, with six prominent ridges, the 
thin exocarp soon drying about the core: seeds glossy, 5 to 6 x 6 to7 
mm., slightly grooved as if the albumen were ruminated.— Plates 43-46.

The typical form and what is called here variety plicata 
are the only spontaneous forms of this species of which I 
have knowledge. It has been in cultivation since 1596 
(Gerarde, Herball, 1359. f.), and to-day is represented by 
a considerable number of garden forms, several of them 
hardy further North than any other species except Y. flac- 
cida, Y. filamentosa, and Y. glauca. Some of these 
approach the following two species while others, scarcely 
presenting mature characters, are but tentatively placed 
anywhere; and a number of imperfectly described gar- 
den hybrids add to the difficulty of properly understand- 
ing Y. gloriosa. The following key, including these hy- 
brids, may serve for the naming of the forms: — 
Leaves not or little plicate, usually concave only toward the end. 
Leaves rigidly spreading. 
From slightly glaucous becoming green, .4 to .8 m. long, 40 to 
50 mm. wide. Y. gloriosa. 
Dwarf and smaller-leaved. f. minor. 
More persistently glaucous. 
Somewhat falcate. f. obliqua. 
With whitish median variegation. f. medio-striata. 
Outer leaves somewhat recurving. 
Leaves but transiently glaucous. var. robusta. 
Persistently glaucous. f. nobilis. 
Leaves narrower. f. longifolia.
