 to a long point, with a very few scattered 

 threads on the margin. They are of a deep green, 

 edged with yellow. The flowers are globular,

Spec. Char., fyc. Leaves serrated 

 and thready. ( Willd.) The stalk 

 and leaves are like those of I", 

 gloriosa ; but the leaves are ob- 

 tuse, and have no spines at their 

 ends. The flower-stalk rises 

 5 ft. or 6 ft. high, and is generally 

 covered with flowers for most of 

 its length. The flowers are larger 

 and whiter than those of Y. glo- 

 riosa, and sit close to the stalk. 

 On the sides of the leaves are 

 long threads, which hang down. 

 Morison states that he saw this 

 species bearing seeds in the garden of Mr. George Crook of Waterstock, 

 near Oxford, in 1675 ; and that the capsules were 3-sided and 3-celled. It 

 is a native of Virginia, and flowers in September and 

 October. It is perfectly hardy.

 Yucca.

Spec. Char., Sfc. Without a stem. Leaves long-linear, 

 rigid ; margin slightly filamentose. Capsules large, 

 obovate-cylindrical. (Pursh.) This species has been 

 sometimes confounded with Y. stricta ; but the leaves 

 are narrower, and more recurved, and the threads 

 on the margin much longer. The whole plant is of 

 humbler growth : the flower-stem is not branched ; and 

 the flowers are more oblong than round, and of a greenish white, without 

 any tinge of purple. Found by Nuttall on the banks of the Missouri; and
