panicle there is little difference between this variety and 

 that here figured. Other varieties are described as having 

 rose-red flowers ; and one, var. viridulum, Reichb. f. (in 

 Gard. Chron. 1887, ii. 272), as having green flowers spotted 

 with reddish-purple. The specimen here figured was 

 obtained from Messrs. F. Sander & Co., of St. Albans, in 

 the spring of 1889, and flowered in the Royal Gardens 

 in October of last year. It was received as var. platyp- 

 terum, Reichb. f. (in Gard. Chron. 1889, i. 168), which is 

 described as having a garlic green lip. 



Descr. Pseudohdbs two to three inches long, sheathed. 

 Leaves many, subsessile, eight to twelve inches long by 

 three to four broad, oblong-lanceolate, acuminate, seven- 

 to nine-nerved. Raceme pendulous, eight- to nine-fld. ; 

 peduncle terete, green, about as long as the inflorescence ; 

 flowers about an inch apart ; bracts lanceolate, half an inch 

 long, appressed to the pedicel, which with the ovary is one 

 and a half inch long. Flowers two and a half inches 

 long from the tip of the dorsal to those of the lateral 

 sepals; sepals white or pale yellowish, closely barred with 

 red ; dorsal erect, slightly incurved, linear-lanceolate, acu- 

 minate, concave, channelled down the back ; lateral, de- 

 flexed under the lip, lanceolate, acuminate, margins broadly 

 revolute. Petals as long as and conniving with the 

 dorsal sepal, oblanceolate, acuminate, coloured like the 

 sepals. Lip very large, cowslip yellow, very broadly 

 flabellate, retuse, the margin in front deeply laciniate, 

 the sides towards the base revolute, and faintly barred 

 with red, the disk excavated and forming an obtuse conical 

 sac or spur ; between the mouth of the sac and retuse apex 

 of the lip is a thickened triangular obtuse callus. Column
