of the spur ; the indexed margins of the stalk ochre 

 coloured, with small red spots. The greatest part of 

 the lip is reddish-brown of the usual tint. The 

 3 aminode is nearly like that of Cypripedium Argus, 

 but the lateral teeth are shorter than in Cypri- 

 pedium Argus. Both the yexillar dorsal sepal and 

 the lines on the petals are very remarkable. It was 

 kindly sent me by Sir Trevor Lawrence, and is a 

 seedling raised at Burford Lodge. It remains in 

 Bower a very long time. When I obtained the 

 flower through Mr. F. Sander it had been expanded 

 for four weeks, and then it was kept in good order in 

 a glass for three weeks. 



Cypripedium Barteti, of which Mr. Sander kindly 

 sent me fresh leaves, has the light garlic-green colour 

 with darker, but with very light angular markings 



all be correct, as I do not [doubt, I can never 

 believe in the plant being a variety of Dendrobium 

 cariniferum. I had, however, no other materials. On 

 January 17, 1887, Mr. F. Sander sent me a few 

 dried flowers collected in Upper Burmah by his 

 traveller, Mr. Michalitz. If the collector had added 

 a piece of the stem and leaves naming might have 

 been possible. What an immense sum has been lost by 

 the neglect to send sufficient materials ! and with what 

 gratitude must we regard such collectors as the two 

 Lobbs, Fortune, Lehmann, Forstermann, and others, 

 who kept in view the interests of their patrons, of their 

 own honour, and of science. Mr. Michalitz, except- 

 ing this lack, is, as I learn, a very careful collector, 

 and informed Mr. F. Sander that he had been told 

 by Mr. Boxall that the plant was my Dendrobium 



indication may be understood from the poor garden 

 plant not displaying the full extent of its black 

 hairy surface, its ornament in its natural state. 



The thickness of the stem at hand is that of a 

 large goosequill. Leaf- blades 3 to 4 inches long by 

 4 lines in breadth at the broadest diameter ; linear 

 ligulate, cuneate at the base, and tapering into a 

 narrow, sharply, bidentate apex. The leaf-blades are 

 rather thin, and when dried prominently nerved. The 

 leaves of Dendrobium cariniferum have the blades 

 three or four times broader, blunt bilobed at the apex 

 which is very little narrower. The short ligulate acute 

 bracts of Dendrobium Wattii are quite covered with 

 black hairs at the period of the development of the 

 flowers — three in one raceme in the specimen kindly 

 given me by Sir Trevor Lawrence. The flowers are

like those found in the group of Cypripedium 

 venustum. 



It is supposed to be a hybrid between Cypripedium 

 Argus and C. philippinense (laivigatum). There is 

 much resemblance to Cypripedium Argus. The 

 latter species might have given the very thick leaves.

This is regarded as a variety of my Dendrobium 

 cariniferum, by Sir Joseph Hooker, who gave a 

 careful description as well as several remarks, and 

 a very good portrait was made by Miss Smith in the 

 magazine above noted. 



My knowledge of the plant began with the inspec- 

 tion of the documents published by Sir Joseph. If 



virgineum (see Gardeners' Chronicle, xxii., n.s., 

 October 5, 1884, p. 520), a plant that has so far 

 proved a monopoly with Messrs. H. Low & Co. This 

 was a mistake. Dendrobium virgineum has the 

 broad leaves of D. cariniferum, but a short blunt 

 chin, shorter, blunt acute sepals and petals, and two 

 callous lines on the disc of the lip, between the side 

 lacinue, reaching only to the base of the mid-lacinia. 

 And now, after five years' suspense, by the kindness 

 of Sir Trevor Lawrence, Bart., I have nearly fully 

 satisfactory materials at hand ! An old stem, the 

 fine leaves, and a three-flowered raceme on the old 

 stem. I lack only the young sheaths, which are said 

 by Sir Joseph to be faintly hairy. The old furrowed 

 stem is more thau a foot long, covered with light ochre 

 or sepia coloured sheaths, covered with very small 

 black points. If those are, as I feel inclined to 

 believe, the bases of the fallen hairs, then Sir Joseph's 



equal in size to those of a good Dendrobium carini- 

 ferum. They are of the purest snow white. The 

 thickened median ligulate patch on the disc is of a fine 

 cinnabar colour, running on to the superior part of the 

 anterior Iacinia, white at the base only. There are few 

 nerves on the lateral lacinias covered with cinnabar 

 colour. The mentum (chin) is sordid reddish- 

 brown. The stalked ovary is quite white. There is 

 some light brown colour at the base of the column 

 where the lip ceases to be adnate. The whole flower 

 lacks the plump shape of that of Dendrobium 

 cariniferum. Its slender chin is quite straight. 

 The dorsal sepal is lanceolate-acute. The lateral 

 sepals are triangular acute without the least 

 vestige of the keels that induced me to give the name 

 of cariniferum. Petals oblong apiculate (acute in 

 Dendrobium cariniferum). This character has been 

 very well represented by Miss Smith, I.e. The
