*Yueca filamentosa. A very common and well- 

 known species, with a much-branched panicle, 4 ft. to 

 6 ft. high, and apple-green leaves, from 15 ins. to 21 ins. 



long by ii ins. to 2 ins. 

 broad at the middle, 

 fringed at the edges with 

 grey filaments 2 or 3 ins. 

 long : the outer leaves 

 spreading, the central 

 ones erect or slightly 

 recurved. This species 

 varies very much when 

 raised from seed : one va- 

 riety (concavd) has short, 

 strong, broad leaves, with 

 the face more concave 

 than in the type; an- 

 other variety (maxima) has leaves nearly 2 ft. long by 

 2% ins. broad, with a panicle 7 ft. to 8 ft. in height. This 

 species flowers with much vigour and beauty, and is well 

 worth cultivating in every garden ; not only in the flower- 

 garden or pleasure-ground, but also on the rough rock- 

 work, or any spot requiring a distinct type of hardy 

 vegetation : and so is its fine though delicate variegated 

 variety. All the varieties thrive best and flower most 

 abundantly in peaty or fine sandy soil. N. America. 



*Yucca flaccida. A stemless species, somewhat 

 resembling Y. filamentosa^ but smaller, with a downy 



Yucca filamentosa.
