 (Denclrobium roseum, Swartz. in Persoon synops. p. 523.) 



L. roseus ; foliis lato-lanceolatis ercctis plicatis, scapo sqnamis lanceolatis 

 acutis membranaceis distantibus vaginato, racenio deiiso obloiigo, brac- 

 teis ovatis acuminatis ovario brevioribus, sepalis spathulatis acutis coii- 

 cavis reflexis, petalis oblongis apiculatis, labelli trilohi lobis rotnndatis 

 intermedio emarginato emu iiiucronc, disco laiuellis tiibus uudulatis 

 serrulatis tuberculo parvo iitrinque. 



A very remarkable terrestrial Orchidaceous plant, im- 

 ported by Sigismund Ruckcr, Esq. from Sierra Leone. It 

 has large plaited leaves, and rich rose-coloured flowers in a 

 close raceme at the end of a scape between three and four feet 

 high. Although the other species of the genus have flowers 

 in which yellow is the predominant colour, this has scarcely 

 any trace of it except in the middle of the lip. We shall take 

 an early opportunity of figuring it. 



38. DENDROBIUM Ruckeri. 



D. Ruckei-i ; caulibus teretibus, foliis ovato-lancoolatis acuminatis planis, flo- 

 ribus gemellis, sepalis patulis obtusiusculis convoxis niargine reticxis 

 lateralibus subtriaugularibus, labelli trilobi lobis rotundatis iutcrmedio 

 undulate axi elevata villosa. 



A Manilla (?) plant, which has lately flowered with Mr. 

 Rucker. It is sweet-scented, handsome, and distinguished 

 by its clear yellow nankin-coloured flowers, the lip of which 

 is a little stained with rose-colour, 



39. CLOWESIA rosea. 



We have lately received from the Rev. John Clowes, a 

 most zealous cultivator of Orchidaceous plants, specimens of 

 a Brazilian species with the habit of a Catasetum, but with a 

 structure quite difl'erent from that of any genus yet described. 

 Its flowers have the chin of the Maxillaridous division, but 

 they diff'er entirely from all' the genera belonging to it in the 

 peculiar structure of the pollen-masses and of the petals. 

 To these points, however, we do not now advert more particu- 

 larly, because we hope soon to have the opportunity of pub- 

 lishing a figure of the plant. The technical characters by 

 which it is to be recognized by Botanists are the following.
