 ifsued as vol. iii. of the Keiv Bulletin. The list includes not only

 few of which have long been out of print and are rare. — W. G. 



Laburnum Adami, Poir, Anatomy and Morphology of (Bei. 

 Bot. Cent. bd. 10, ht. 3, p. 144). — Dr. R. Lambert gives a full discussion 

 of the anatomical details of the hybrid Laburnum Adami, Poir, of Cytisus 

 purpureus, and of the branches resembling the latter plant which appear 

 on L. Adami as bud variations. These branches do not essentially differ 

 from those of the true C. purpureus, but are very different both anatomi- 

 cally and in their general appearance from the branch of the hybrid which 

 produces them. As a study of the anatomy of hybrids this paper should 

 be consulted, and the photographs illustrating the origin and appearance of 

 these peculiar branches are most interesting. — G. F. S.-E.
