hybrids due to crossing the more hardy alpine species. 

 So far as American gardens are concerned the follow- 

 ing, not yet introduced or rare in cultivation (some of 

 them not here described), would be desirable novelties: 

 V. Dieffenbachii, V. gigantea, V. Barkeri, V. Lewisii, V. 

 leiophytta, V. Bollonsii, V. cmamala, V. vernicosa, V. 

 monticola, V. Menziesii, V. decumbens, V. tetragona, V. 

 Armstrongii, V. propinqua, V. loganioides, V. Lavaudi- 

 ana, and V. Raoulii. Those desiring more information 

 about the shrubby veronicas should consult Cheese- 

 man's "Manual of the New Zealand Flora," Welling- 

 ton, 1906, and the subsequent volumes of the ''Trans- 

 actions of the New Zealand Institute."
