ir.O ENGLISH BOTANT. 



suborbicular, deltoid, obtuse, white with a yellow s]iot, and with 3 to 

 5 yellow interrupted longitudinal crests; the basal portion swollen 

 below and subsaccate but Avithout any spur at the base. Rachis and 

 ovaries mdistinctly glandular-pubescent, or subglabrous. 



In woods and bushy places, especially on chalky soil. Frequent in 

 the south of Eno;land, but becoming rare in the north. I have not seen 

 specimens from farther north than Gloucester, Oxford, and Essex; 

 but it certainly occurs, though very sparingly, in Cambridgeshire and 

 Herts. It is reported from Nottingham, Derby, Lancashire, West- 

 moreland, Perth, Isle of Arran, and Argyle; but these counties require 

 confirmation. In the Scotch stations, in all probability, the plant found 

 was C. ensifolia. 



England, Scotland ? Perennial. Summer. 



C. grandiflora is very similar to C. ensifolia, but it is a stouter 

 plant, and the rootstock often produces numerous stems, so that the 

 plant grows in tufts ; these stems are 1 to 2 feet high, the leaves are 

 broader than those of C. ensifolia and much shorter, 2 to 4 inches at the 

 time of flowering. The leaves decrease more gradually upwards, and 

 the lower bracts are similar to the leaves but narrower. The flowers 

 are rather larger, about f inch long, of not so pure a white, not so 

 much attenuated at the base, especially on the lower side, where the 

 basal portion of the labellum is tumid. The spike also occupies a 

 greater portion of the stem, often nearly as much as one half of it. 

 I have seen it nearly a foot long when the stems were 2 feet high. 

 The flowers are more erect, and the leaves are thicker.

Tribe III.— ARETHUSEiE. 



Anther terminal, ultimately free, deciduous ; pollen-masses stalked, 

 consisting of grains which are pulpy or subpulverulent, but more or 

 less coherent. 



GENUS XIV.— -E P I P O G U M. Gmel 



Perianth coloured ; segments spreading-ascending, all turned in the 

 opposite direction from the labellum ; labellum uppermost, spurred at 

 the base, 3-lobed, the lateral lobes small and spreading, very large, 

 entire, concave, glandular on the inside. Column short, seraicylindrical. 

 Anther terminal, ultimately free and lidlike, stalked; pollen-masses 

 2, stalked, with the stalks united to a single gland ; ijollcn pulpy.
