 cultivated forms. 



C ANNAS OF THE LAST TWENTY YeAKS. 



Latterly the attention of the raisers of new varieties has been 

 mainly directed to endeavouring to obtain large, bright-coloured, 

 copiously flowering forms of late growth which flower early. 

 The principal new forms of this group have been sent out by 

 Crozy and Sisley of Lyons, Yilmorin of Antibes, and Lemoine 

 of Nancy ; and these are the Cannas which are most widely 

 diffused in cultivation at the present day. They are all, I 

 believe, hybrids between iridiflora and forms of Eucanna, with 

 the short tube of the latter but the large staminodia of iridiflora. 

 The red-flowered are probably mainly hybrids between Ehemanni 

 and Warccwiczii. Amongst these are W. Pfitzer, Revoil Massot, 

 Victor Hugo, Paul Bert, Edouard Andre, and Maurice Revoise. 

 The yellow-flowered forms are allied to Bouche's Fintehnanni, 

 and are probably hybrids between Ehemanni and glauca. 

 Amongst these are Capricieux, Guillaume Constan, lutca 

 nplendcns, Deputy Henon, and Henri Louis Yilmorin. Figures 

 of some of these will be found in the Bcvue Horticole, 18G0, 

 p. 150; Gartenflora, tab. 1303, and the Garden for May 2, 1889. 



Maron. — M. Maron, of Saint- Germain -les-Corbeil, has suc- 

 ceeded in raising a cross between C.liliiflora and some of the Crozy 

 ('annas nearly allied to C. Warccwiczii. This is described and 

 figured in the Bevuc Horticole for 1892, p. 540, under the name 

 of Madame Jeanne Sailier. It resembles closely C. Ehemanni, 

 having a short tube and three spreading bright red staminodia 

 a couple of inches long by half as broad. 



Petersen. — The 107th fasciculus (vol. iii. part 8) of the great 

 "Flora Brasiliensis," published by authority of the Brazilian 

 (iovernment, published in 1890, contains an excellent monograph 

 of the South American Cannas by Dr. O. G. Petersen, of the 

 University of Copenhagen, with uncoloured plates of several of 

 the species. Dr. Petersen estimates the number of species at 

 twenty, and gives many notes on the types of Bouche, having 

 studied the coloured unpublished figures in the herbarium at 

 Berlin.
