rica, no. 620, has produced a pair of pale violet blossoms with 
Messrs. Loddiges. 
43, POLYSTACHYA refleca ; pseudo-bulbis conicis subcompressis annu- 
latis, foliis . . . . , scapo subclavato apice racemoso, sepalis expansis 
sub apice emarginato mucronatis lateralibus 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 deliciosa 3 arbuscula spinosa, foliis lanceolatis utrinque attenu- 
atis 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 herbaceo 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 hirsutis 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 (Tonsz); pseudobulbis brevibus ovatis apice subdi- 
phyllis, foliis oblongis undulatis racemis subeequalibus, bracteis margine 
revolutis superioribus linearibus reflexis, racemis erectis, labelli trilobi
