{Clavija ornata Don) would grow- 

 readily from a cutting formed of a 

 leaf, he conceived the idea of cutting 

 a leaf in two, and trying to strike 



both parts. He did so, plunging the 

 plants in the pit of a hothouse, and 



^ succeeded in striking both ; but he 



' found that though the lower half of 

 the leaf made roots in three months 

 (see fig 9), the upper half {fig. 10) 

 was nearly double that time before 



: it was quite established. The dotted 

 lines in fig. 10 show where portions 



j of the leaf were cut off. In June, 

 1840, the two half leaves had become 

 beautiful and healthy plants, which 

 it was impossible to distinguish 

 from those struck in the usual 

 manner. Half leaves of various 

 plants have also been rooted in 

 charcoal, in Germany.

GY'CAS.—C'i/cadece. — A kind of 

 herbaceous Palm, requiring the heat 

 of a stove, and remarkable for its 

 curious root-like stem, and enormous 

 fern -like leaves. It very rarely pro- 

 duces seed in England, and when it 

 does, the seeds are placed on the 

 margin of the leaves. The male 

 flowers are in cones. It shoidd be 

 grown in a strong rich loam. 



Ct'clamex. — Pi'imuldcece. — 

 Handsome and curious tuberous- 

 rooted herbaceous plants. C. eiiro- 

 poehim is a native of Switzerland, and 

 is very fragrant; C. coum and C. 

 vernum are natives of the South of 

 Europe ; and all these kinds are 

 hardy in British gardens, and require 

 no other care than to be grown in 

 light rich soil. 0. iiersicuiii is a 

 greenhouse species, the tubers of 

 which should be planted in well- 

 drained pots, early in September, and 

 kept in the open air till they have 

 thrown out leaves, when they should 

 be removed to the greenhouse. They 

 require plenty of air, and but very 

 little heat ; and during the months 

 of November and December, they 

 should have very little water ; though, 

 when the flowers begin to form, they
