42" PEOFESSOB LINDLEY's CONTEIBtTTIONS TO 



Dr. Hooker's admirable sketches. The Sikkim plant may therefore 

 be defined thus : — 



243. A. HYSTRix ; foliis oblongis, petalis linearibus, labelli lobis late- 

 ralibus planis intermedio trilobo fimbriate apice recurve brevioribus. 



Sikkim, at 4000-6000 feet elevation, /. D. H. (204). 



The flowers are yellow with crimson streaks along the sepals 

 and petals ; the middle lobe of the lip, which is deeply fringed 

 and crimson, consists of two lateral lobes diverging at the base, 

 and converging upwards over a circular recurved middle lobe. 



244. A. decumbens. Griff. Not. iii. t. 320, a Burmese plant, seems te be 

 a true Aerides ; but I have seen ne specimen. 



Vanda, H. Brown. 

 To the species described in ' Folia orchidaeea,' the following fine 

 addition to the section Eieldia has to be added : — 



245. V. UNDULATA ; foliis distichis obtusis bilebis peduncule apice 

 pauciflore triple brevieribus, sepalis petalisque recurvis membranaceis 

 lineari-lanceolatis undulatis, labello breviore carnose cochleate in 

 laminam linearem acutam sub apice tuberculatam preducto. 



Sikkim, Cathcart, Ic. 



The whole habit is that of V. spathulata and ccerulescens. The 

 flowers are fully two inches in diameter, with thin white sepals 

 and petals tinged with pink, and a yellow fleshy lip fasciated 

 internally with red lines. I have only seen a drawing prepared 

 by Mr. Cathcart' s artists. 



T^NioPHYLLUM, Blume. 



246. T. Alwisii; minutissimum, spica pauciflora erecta, bracteis cari- 

 natis triangulis, perianthii laciniis omnibus connatis acutis confor- 

 mibus, calcare hemisphaerico, polUniis pyriformibus in glandulam 

 sessilibus. 



On the branch of a Symplocos, Ceylon, DeAlwiz. 



The smallest Orchid I know, the flat roots not being more than 

 1| inch long, and the stem, including flowers, J inch. The whole 

 plant is pale green, even the flowers having no other colour. Mr. 

 Thwaites, who sent me a drawing of it (and I have seen nothing 

 more), proposed to call it Alwisia minuta, after his excellent native 

 draughtsman, who was the first to discover it ; and if the figures 

 in Blume and the Xenia represent the invariable characters of 

 Ta?niophyllum, this and Bendrohium algosum of Eeinwardt's MSS. 

 ought to be distinguished ; but Prof. Eeichenbach, jun., who has 

 had the opportunity of examining Tseniophylla, assures me that 

 this is one, and I possess no materials on which to form an opinion 

 for myself. *
