Calla, A New (Bev. Hort. p. 374 ; August 16, 1902).— C. Elliottiana 



x C. albo-maculata, raised by Mr. J. Tailby, Wellesley, Mass. More 

 floriferous than either parent ; spathes primrose-yellow ; foliage white 

 spotted. Very robust and easy of culture ; planted out end of May, it 

 flowers until the frosts ; the tubers are then lifted, dried, and stored like 

 Potatos. Comes quite true from seed sown in the open in April.

Calla, New Yellow (E. 0. Orpet in Amer. Gard. xxiii. p. 463, fig. 

 101; 19/7 1902).— The result of crossing Bichardia (Calla) Elliottiana 

 with B. albo-maculata. It was raised by Mr. J. Tailby, of Wellesley, 

 Mass. Foliage vigorous and prettily spotted ; spathes primrose-yellow, 

 produced in great profusion ; altogether a marked improvement on both 

 parents. The cross is said to have reproduced itself true to seed from the 

 first.— C. C. H.

Camassias. By George B. Mallett (Garden, No. 1,603, p. 94 ; 

 9/2/1902). — The value of Camassias for grouping in the border, shrub- 

 bery, and woodland, or in any situation where it is desirable that the 

 plants should be able to take care of themselves and thrive, is slowly but 

 surely gaining recognition, despite the drawback of a singularly confused 

 nomenclature, and the dearth of authoritative information about them. 

 The genus contains five well-marked species, of which very full descrip- 

 tions are given. — E. T. C.

 food-plants, medicines, &c, and some interesting short notes are appended, 

 chough the list embraces chiefly such as are well known in our colonial 

 gardens— H. 31. W.
