rica, no. 620, has produced a pair of pale violet blossoms with 

 Messrs. Loddiges. 



43. POLYSTACIIYA refiexa ; pseudo-bulbis conicis subcomprcssis annu- 

 laris, foliis . . . . , scapo subclavato apice racemoso, sepalis expansis 

 sub apice emarginato niucronatis latcralibus maximis, labello pandurato 

 medio crenulato genuflexo pulvinato apice dilatato membranaceo. 



This singular Orchidaceous plant is a native of Sierra 

 Leone, where it was found by Mr. Whitfield. It flowered in 

 February in the garden of Chiswick House, under the care 

 of Mr. Edmunds. Its leaves are at present unknown. The 

 flowers are white with a faint tinge of pink, and spread flat, 

 so as to look at first sight very unlike those of a Polystachya. 

 The lip is slightly tinged with green, abruptly bent back in 

 the middle, and below the bend furnished with a bright yellow 

 cushion of the most curious jointed hairs, which are arranged 

 so compactly that the whole seem to form one solid mass. 



44. CITRUS cleliciosa ; arbuscula spinosa, foliis lanceolatis utrinque attenu- 

 ates subdentatis, petiolis linearibus; fructu compresso (2. poll, diametr.) 

 pulpa sapidissima corticeque fulvo-aurantiaco. Ten. Ind. Seminum, 1840. 



This is said to be a new species of Orange, allied to the 

 Citrus nobilis; or Mandarin orange, with which it is con- 

 founded in Italian gardens. It is stated to differ in being a 

 spiny plant, with somewhat toothed leaves, and a small fruit 

 not more than two inches in diameter, by no means red either 

 inside or outside. It is supposed to come from China ; 

 flowers in April, and ripens the fruit in December. 



45. CONVOLVULUS verrucipes ; caule volubili lierbaceo foliis cordatis 

 acuminatis, inferioribus integerrimis, superioribus basi trilobis vel sub- 

 angulatis repandis ; pedunculis unifloris angulatis verrucosis (8-10 lin. 

 long.) calycinis foliolis ovali-oblongis (2 lin. lat. 4. lin. long.) corollis 

 albis calyce vix duplo longioribus ; capsulis birsutis trilocularibus tri- 

 spermis. Ten. Index Seminum, 1840. 



An annual related to C. sibiricus, flowering in July. Its 

 native country is unknown to Professor Tenore, who says 

 nothing more about it. 



46. ERIA bractescens (Tonsse); pseudobulbis brevibus ovatis apice subdi- 



phyllis, foliis oblongis undulatis racemis subsequalibus, bracteis margine 

 revolutis superioribus linearibus reflexis, racemis erectis, labelli trilobi
