50. DENDROBIUM discolor; caulibus erectis fusiformibus, foliis oblongis 



obtuse eniarginatis disticbis, racemo terminali multifloro, sepalis peta- 

 lisque lineari-oblongis patulis crispis, labelli crenulati lobis lateralibus 

 acutis intermedio lanceolato acuto : lamellis 5 undulatis. 



Although obtained by Messrs. Loddiges from the Bota- 

 nical Garden at Buitenzorg, I cannot recognize this species 

 among those mentioned by Dr. Blume. It has a most sin- 

 gular appearance, with stout erect stems four feet high, 

 swollen in the middle, and terminal racemes of about 1(3 dingy 

 yellowish brown flowers, as much curled and wavy as those 

 of a Gloriosa. The lip has the same dull dirty colour, except 

 along the middle, where it is decorated with five deep wavy 

 plates of a bright violet. It is of the same section as the 

 sweet-scented Dendrobium crumenatum, now so rare in our 

 gardens, if it exist at all. 



51. LINARlA glandulifera ; annua, villoso-viscosa, pilis glanduliferis un- 



dique tecta, caulibus debilibus, foliis oppositis ovato-subrotundis, in- 

 ferioribus petiolatis interdum vage dentatis obtusis, superioribus sessili- 

 bus integerrimis, floribus axillaribus solitarhs subsessilibus, calycinis seg- 

 mentis ovatis ; corollis exiguiis, labio superiore atropurpureo, inferiore 

 palatoque flavo, calcare incurvo albo. Tenore Index Seminum, 1840. 



An annual with small purple flowers, sent from England 

 to Professor Tenore by Mr. Fox Strangways. It is said to be 

 allied to Linaria dealbata and lanigera ; but it differs from 

 the first in its sepals being ovate and obtuse, not lanceolate 

 and acute, and also in its much smaller leaves and in the 

 colour of the flowers. The sessile, not long-stalked, flowers 

 divide it from L. lanicrera. 



52. SEVERINIA buxifoha; arbuscula spinosa ; foliis eniarginatis perennan- 

 tibus ovali- oblongis subsessilibus integerrimis parallele venosis obtusis; 

 floribus axillaribus fasciculatis vel sobtariis Tenore hid. Seminum, 1840. 



Under this name Professor Tenore distinguishes the 

 Citrus buxifolia of the gardens, which he regards as a new 

 genus, the character of which he states as follows : 



SEVERINIA. Calix quinquedentatus, corolla pentapetala, stamina decern 

 pentadynamica, antberse semilunares biloculares, pistillum unicum 

 stigma simplex. Acinus dispermus. 



53. DENDROBIUM elongatum. (Eudendrobium, foliis planis, floribus race- 

 mosis, labello trilobo.) A. Cunningh. in Hot. Reg. 1830. misc. 33.
