178 GENERAL REVIEW. 



Crinwn capense which had been fertilised with pollen from C. 

 revolutum was well developed, every ovule producing a seedling 

 plant, a result not to be obtained by fertilising it with its own 

 pollen; while at p. 356 he further observes that all the hybrid 

 Crinums raised between C. capense and tropical species, which 

 are now very numerous, are hardy enough to stand out of doors 

 against the front wall of a stove, where, if a mat is thrown over 

 them in sharp frosts, they preserve most of their leaves, and from 

 May to November continue to throw up a succession of flower- 

 stems in great perfection. Crinum hybridum (C. erubescent x 

 capense] (see ' Bot." Mag.,' t. 2336) was raised from a seed 

 ripened in a pond at Spofforth in 1818. In 1874 I saw a 

 splendid plant in the late Mr S. Rucker's garden at Wands- 

 worth in full bloom, and in the Dublin Botanic Garden also. 

 C. capense forms a noble object in autumn. (See Herbert's 

 ' Amaryllidaceae/ p. 272, for a list of hybrids and crosses, with 

 their parentage, &c.) 



Hippeastrum (Knight's Star Lilies). A group of very 

 showy, and for the most part deciduous, South American and 

 West Indian bulbs, generally grown in gardens under the name 

 of Amaryllis, from which, however, they differ in being decidu- 

 ous, and also in being more readily forced, a general charac- 

 teristic, indeed, of nearly all deciduous bulbs. The best-known 

 species are H. aulicum^ H. equestre, H. regium, which bear 

 scarlet, crimson, or orange-red flowers with a greenish centre. 

 H. vittatum (H. Harrisonii) is pure white striped with crimson. 

 H. pardinum is creamy yellow, profusely speckled with ver- 

 milion; and H. reticulatum, an evergreen species, has rosy 

 flowers finely netted with bright red. The hybrids in this 

 genus are innumerable, as all the species, or nearly all, inter- 

 breed freely. One of the most brilliant and beautiful of all 

 is the old H. Ackermanni-pulcherrimum. H. regina-vittatum 

 is figured as an illustration to a valuable paper on Hybrid 

 Hippeastrums in the Transactions of the Horticultural Society, 

 v. 337. A numerous race of very showy hybrids has recently 

 been raised by Messrs Veitch between H. pardinum and H, 

 Leopoldi. 



The first hybrid Hippeastrum, according to Herbert, was H. 

 Johnsoni, named after its raiser, a nurseryman, who fertilised 

 H. vittatum with pollen from H. regium. Numerous seedlings 

 were afterwards raised between H. Johnsoni and such kinds as 

 H. psittacinum a green and scarlet flowered plant introduced 

 from Brazil in 1816 ; H. regium, the Mexican Lily, introduced 

 in 1725 ; H. aulicum, green and red, also Brazilian, introduced 

 in 1810 : while, more recently, numerous beautiful hybrids have
