6. Leucoium vernum, SPRING SNOWFLAKE. Like the Snowdrop on 

 a larger scale, but the six pieces of the perianth all alike, ovate and entire, white, 

 with a green spot outside near the apex ; anthers blunt. 



L. sestrvum, SUMMER SNOWFLAKE, is commoner than the last in gar- 

 dens, taller (the 2-edged scape and leaves 1 or 2 high) ; flowers several and 

 smaller, in June. 



7. Amaryllis, AMARYLLIS. Man. p 455. Plants with strap-shaped leaves 

 and a simple scape from a coated bulb ; flowers one or more, generally red or 

 pink, large and showy, lily-like, regular or considerably irregular. Many hy- 

 brids are cultivated. 



A. Belladonna. Flowers several in an umbel, 4' long, between funnel- 

 form and bell-shaped, with hardly any tube, rose-colored, almost regular ; sta- 

 mens arid style declined ; leaves "appearing after the flowering season. 



A. ReginSB, with 2-4 equally large deep-red flowers ; leaves two-ranked. 



A. formosissima, JACOBJEA LILY, or ST. JAMES'S CROSS. Scape 

 bearing one large rich crimson-red flower, which is declined, with hardly any 

 tube, and as it were 2-lipped, three of its divisions upwardly recurved-spread- 

 ing, the other 3 turned down, their lower portion involute around the base 

 of the deflexed stamens and style. 



8. Agave. Man. p. 456. To this belongs that very striking plant of con- 

 servatories, the Mexican 



A. Americana, CENTURY-PLANT, AMERICAN ALOE, with very thick 

 and large spiny-pointed and spinulose-margined leaves in a close cluster 

 at the root : it propagates freely by offsets from the root : when it blossoms 

 (which it does in its native tropics in 7 or 8 years, but in the colder northern 

 countries after so many years that it has obtained the name of Century-Plant) % 

 it rapidly sends up a scape as thick as a man's leg, 15 to 30 feet high, bearing 

 an immense panicle of yellowish-green flowers ; and the plant dies as the pods 

 ripen their seeds. A variety has the leaves striped with yellowish or white.
