eoriophora X 0. latifolia) and x Gymnadenia Le Grandiana (G. 

 conopsea x 0. macnlata). The following is a translation of his 

 description of the latter: " Discs of the pollen-masses free, not 

 enclosed in a pouch. Tubercles of the root two-lobed. Stem 

 slender, leafy, two decimetres in height, not hollow. Leaves linear- 

 lanceolate, somewhat channelled above, obscurely spotted only at 

 the top; bracts reddish, one-nerved, about as long as the ovary. 

 Flowers few, in a short spike, lilac-coloured. Upper perianth-leaves 

 equal, lanceolate-acuminate, the two lateral ones patent, ascending, 

 not spotted. Lip oblong, three-lobed, the middle lobe entire, rather 

 longer but narrower than the lateral lobes, with streaks and spots 

 symmetrically arranged. Spur filiform, at least as long as the 

 ovary, and pointing downwards. Plant exhaling a faint odour of 

 vanilla. " The Sevenoaks plant, if some allowance is made for the 

 well-known variability of hybrids, agrees fairly well with the above 

 description. The number of flowers and length of spike obviously 

 depend on the luxuriance of the individual ; the lateral sepals are 

 usually rather horizontal than ascending, and are spotted. The 

 ground colour of the flower resembles that of G. conopsea, the 

 markings being only slightly darker. The spur is certainly much 

 less filiform than in G. conopsea, and I have found no trace of free 

 nectar. The odour is that of G. conopsea, but somewhat fainter, 

 and under some conditions hardly perceptible. The whole upper 

 surface of the leaf is spotted, but more faintly than is usual in 

 O. maculata. It may be of interest to note that the viscid matter 

 of the discs seems hardly fluid enough to insure the easy removal 

 of the pollen-masses. This is not surprising, as it is not protected 

 by a pouch, as in 0. macnlata, and is much more exposed than in 

 G. conopsea. The ovaries readily swell if pollen, even that of 

 Habenaria chloroleuca, be applied, but I cannot say whether good 

 seed was formed. I am persuaded that a careful search in places 

 where both parents occur would often be rewarded by finding the 

 hybrid, and possibly this remark applies also to the hybrid between 

 G. conopsea and 0. latifolia, which is found on the Continent.

Cephaloziella patula (Steph.) Schiffn. in Britain. — When 

 botanizing in Crete in the spring of last year I gathered a Cephalo- 

 ziella with abundant perianths, which Prof. Schiffner kindly identi- 

 fied for me as C. RaumyartneH recently described and figured by 

 him in Verb, der K.K.'Zool.-Bot. Ges. in Wien, 1906, p. 273. 

 Prof. Schiffner has subsequently shown (in Oesterr. Bot. Zeit. 

 1907, 48) that this species is the same as Cephalozia patula Steph. 

 in Bull. Soc. Bot. Ital. 1905, 210, and this latter specific name 

 consequently has the priority. Shortly after I had received this 

 identification, I gathered an hepatic on a very familiar part of the 

 chalk downs close to Lewes which appeared to be identical with 

 the Cephaloziella from Crete, and which identity Mr. S. M. Macvicar
