200 HANDBOOK OF AMARYLLIDE.E. 



G-8 in. long below the rosette of leaves, 2-3 in. diara. Leaves 

 about 30 in a rosette, lanceolate, bright green, firm in texture, 

 2-3 ft. long, 2-3 in. broad at the middle, smooth on the face, 

 scabrous on the back, scarcely pungent at the tip, armed on the 

 margin with remote horny uncinate prickles. Panicle with 

 peduncle (according to Hasskarl) reaching a height of 30 ft. or 

 more ; branches copiously compound, the centr;il ones G-9 long. 

 Flowers greenish white, sweet-scented ; segments oblong, an inch 

 long. 



Hab. Tropical America, The descriptions of Miller and Alton are very 

 brief. In the absence of reliable specimens I have simply copied Jacobi and 

 Hasskarl. See also Carriere in Rev. Hort. 1877, 234, figs. 39—40. We have a 

 photograph fram Prof. Miquel's collection, of a young i^lant of F. interrupta 

 Hort. Van Houtte, ^Yhich, according to Jacobi, is the genuine tnberosa. All the 

 species of the cuhensis group seem to come very near to one another, and I 

 much doubt their being all really distinct specitically. 



4. F. GEMiNispiNA Jacobi, Monogr. 282. — Trunk reaching a foot 

 long, 5-G in. diam. below the rosette of leaves. Leaves 40-50 in 

 a dense rosette, lanceolate, 3-4 ft. long, 6-8 in. broad at the 

 middle, narrowed to 3^-4 in. above the base, bright green, smooth 

 on the shallowly channelled face, very scabrous on the back, the 

 short brown point subpungent, the edge armed with distant deltoid- 

 uncinate brown spines ^ in. long, many, especially about the 

 middle of the lea^ conHuent, so as to have a hook pointing both 

 ways. Liflorescence unknown. 



Hab. Tropical America. Described from a fine plant which has been in 

 the Cactus House at Kew for many years, but has never flowered. Probably 

 this is the plant placed as a variety of tuberosa by Willdenow and Alton.

 above the base, subpungent at the tip, the margin armed with 

 distant hooked large brown horny prickles. Peduncle 8-10 ft. long 

 below the panicle ; bract-leaves distant, lanceolate, 3-4 in. long. 

 Panicle 5-6 ft. long, 3 ft. broad ; branches simple ; lower flowers.
