49. Upon a Mode of covering the naked Branches of Fruit Trees 

 •with neiv Wood. By Samuel Spyvee Street, Esq., of Penryn, 

 Cornwall. 



Wall and espalier trees often become naked for a foot or 

 two on each side of the main stem ; but by ringing the lateral 

 branches at 6 or 8 in. distance from the main stem, young 

 shoots will be thrown out between the ring and the stem, 

 which may be trained over the naked parts at pleasure. 



50. An Account and Description of the Species and most remarkable 

 Varieties of Spring Crocuses, cultivated in the Garden of the 

 Horticidtural Society. By Joseph Sabine, Esq. F.R.S. Secre-

Hardy bulbous plants have been the object of Mr. Sabine's 

 attention for nearly 30 years ; he had formed an extensive 

 collection of them, and, with that devotion to the Horticultural 

 Society for which he has ever been distinguished, he pre- 

 sented the whole collection to the experimental garden at 

 Kensington, in 1818. This collection included a very ex- 

 tensive assortment of spring crocuses procured from all 

 quarters, to which additions have since been made. 



Linnaeus, in 1753, had only one species of Crocus, C. 

 sativus, considering the autumnal or saffron crocus (C offici- 

 nalis), and the spring crocus (C vernus), as varieties. Will- 

 denow, in 1797, made Linnaeus's two varieties species, calling 

 the autumnal crocus C. sativus, and the spring one C. vernus. 

 The crocus has been found wild in the southern parts of 

 Europe, and in the temperate regions of Asia; and botanical 

 travellers " have proved the existence of many kinds of 

 Crocus in a wild state." Most of these remain to be described, 

 and a monograph is preparing by M. Gay of the garden of
