84. PISONIA Olfersi'an'a (Link, Klotzsch, & Otto, p. 36. t. 15.);arboresceus, 

 inermis ; foliis oppositis, interdum quaternis, petiolatis, magnis, oblon- 

 gis, basi apiceque attenuatis, caruoso-membranaceis, arcuato deflexis, 

 subundulatis, iutegerrimis, laete-viridibus, undique albido-punctulatis, 

 glabris ; floribus terminalibus, cymosis, alutaceo-roseis, ad basin bracteis 

 tribus, minutis, inaequalibus instructisj masculis beptandris absolete- 

 quiaque-dentatis, filamentis albidis, antberis fuscescentibus ; femineis 

 quinquelobatis, stigniatibus candidis, subexsertis. 



A singular Brazilian hothouse shrub, with opposite oblong 

 lanceolate leaves, and small stiff panicles of dull pink flowers, 

 partly male, partly female. It has little beauty. 



85. ODONTOGLOSSUM Ehrenb'ergil (Link, Klotzscb, & Otto, p. 38. t. 16). 



This Mexican epiphyte is surely the same as O. Rossii 

 figured in this work, but not so fine a specimen. 



86. DENDROBIUM acerosum ; caulibus brevibus teretibus glabris, foliis car- 

 nosis teretibus obtusiusculis, racemo terminali brevi paucifloro, bracteis 

 membranaceis convolutis, floribus semiclausis longe cornutis, sepalis pe- 

 talisque erectis acutis, labello cuneato emarginato apice crispato calvo. 



A small uninteresting plant from Sincapore, imported by 

 Messrs. Loddiges, who bought it of Cuming, ( 357 )• I* 

 is near O. teretifolium, but has smaller flowers, shorter leaves, 

 and quite a different lip. The flowers are dull yellowish 

 pink, with pink stripes. 



87. CYRTOCHILUM maculatum; var. parviflorum; labello subhastato la- 



ciniis lateralibus majoribus. 



Messrs. Loddiges have flowered a Mexican plant, (no. 794-) 

 which in so many respects corresponds with the now common 

 C. maculatum, that I cannot regard it as more than a variety, 

 but which nevertheless differs in having smaller flowers, with 

 the lateral lobes of the lip so much larger than usual as to 

 give it a hastate appearance, and with a frequent union be- 

 tween the lower sepals more or less complete. This circum- 

 stance breaks down yet more the limits between Cyrtochilum 

 and Oncidium. 



88. AOTUS lanigera. A. Cunningh. Bentb. dissert, de legumin. gen. p. 78. 



This is a pretty greenhouse shrub, with narrow deep 

 green sharp-pointed leaves, and thick racemes of yellow pea- 

 June, 6?.— 1841. tj
