138 COOL ORCHID GROWING. 



variety of C. Calceolus, from wliicli I can distinguisli it by no 

 satisfactory [structural] character. I think, when further 

 examined, it will be found to merge into Calceolus, which has 

 already been found in Dahuria, and which, if Thunberg's C. 

 Calceolus is rightly named, must extend into Japan." 



G. candidum (N. America). — This species has been recently 

 figured in the " Botanical Magazine," t. 5,855, and is a small, 

 white-flowered kind not so beautiful as some of its con- 

 geners, but worth adding to a general collection. 



C. i:>almifolium. — This curious tall-growing species I have 

 not seen. Its stems grow several feet in height, and its leaves 

 in texture resemble those of a Sobralia or Palm, as its specific 

 name indicates. We believe this species was introduced to 

 Kew years ago, but is probably not now in cultiv^ion, a 

 remark which will apply to several of the above-named 

 species.
