YOUNGIA. A genus of herbaceous 

 plants, belonging to the Compositce. The 

 leaves are long, variously-divided, mem- 

 branous ; and the flower-heads small, each 

 surrounded by a cylindrical involucre of 

 about eight scales, with an outer row of 

 five smaller scales ; florets ligulate ; fruits 

 oblong compressed striated, surmounted 

 by a white thread-like pappus. The species 

 are natives of India, Japan, China, and the 

 Mauritius. [M. T. M.] j

YUCA. A name in the Spanish- American

YUCCA. A genus of Liliacem, sometimes 

 assuming an arborescent habit, producing 

 a crown of linear-lanceolate more or less 

 rigid leaves, and from the centre of each 

 crown an erect panicle of showy whitish 

 flowers. They are chiefly found in the 

 Southern States of America and in Mexico, 

 one or two extending to Tropical America. 



The flowers have a six-leaved perianth, 

 which is beil-shaped ; six stamens, the fila- 

 ments flattened and broadest at top ; a 

 three-celled ovary, with three sessile stig- 

 mas; audan oblong bluntlyhexagonal three- 

 valved capsule containing many seeds. 

 They are very handsome garden plants, 

 most of them nearly or quite hardy. In 

 F. gloriosa, one of the stateliest of the 

 species, the crown of leaves becomes ele- 

 vated on a stout stem, and the panicle is 

 three feet or more in length, branching out

on every side. In some, as Y . fllamentosa, 

 the leaves give off from their margin 

 thread-like bodies, which hang loosely; and 

 in one tender species, A. schidigera, these 

 bodies are so large and broad as to re- 

 semble carpenter's shavings. The leaves, 

 treated like hemp and flax, afford a fibre 

 which may be used in the manufacture of 

 cloth or cordage ; and the macerated stems 

 deposit a feculent matter, from which 

 starch may he obtained. At Carthagena a 

 starch or glue of this kind is made from 

 the stem of T. gloriosa. These plants are 

 popularly called Adam's-needle. [T. MJ

ZACYNTHA. A genus of Composite, so 

 called because first discovered in the island 

 of Zante, the ancient Zacinthus. The 

 species is an annual, with divided leaves, 

 and both terminal and lateral heads of 

 flowers. The involucre is ultimately fleshy, 

 its inner scales folded, the outer ones mem- 

 branous spreading ; receptacle flat, with- 

 out scales; florets all ligulate; achenes 

 slightly curved, flattened, wingless; pap- 

 pus hairy, in one row. Z. verrucosa is some- 

 times grown as an annual. [M. T. M.]
