130 ENGLISH BOTANY. | 
suborbicular, deltoid, obtuse, white with a yellow spot, and with 3 to | 
5 yellow interrupted longitudinal crests; the basal portion swollen — 
below and subsaccate but kaa any spur at the base. Rachis and 
ovaries indistinctly glandular-pubescent, or subglabrous. 
In woods and bushy places, especially on chalky soil. Frequent in 
the south of England, 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 eradually upwards, and 
the lower bracts are similar to the leaves but narrower. The flowers 
are rather larger, about 2 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. 
White Helleborine. 
French, Eipipactis blanc-jaundtre. German, Grossbliithiges Zymbell-raut. 
Tre ITI.—ARETHUSEE. 
Anther terminal, ultimately free, deciduous; pollen-masses stalked, 
consisting of grains which are pulpy or subpulverulent, but more or 
less coherent. 
GENUS XIV—-EPIPOGUM. Gime. 
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, semicylindrical. 
Anther terminal, ultimately free and lidlike, stalked; pollen-masses 
2, stalked, with the stalks united to a single gland; pollen pulpy.
