84. PISONIA Olfersiana (Link, Klotzsch, & Otto, p. 36. t. 15.);arborescens, 
inermis ; foliis oppositis, interdum quaternis, petiolatis, magnis, oblon- 
gis, basi apiceque attenuatis, carnoso-membranaceis, arcuato deflexis, 
subundulatis, integerrimis, lete-viridibus, undique albido-punctulatis, 
glabris ; floribus terminalibus, cymosis, alutaceo-roseis, ad basin bracteis 
tribus, minutis, inequalibus instructis; masculis heptandris absolete- 
quinque-dentatis, filamentis albidis, antheris fuscescentibus ; femineis 
quinguelobatis, stigmatibus 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 Fhrenbergii (Link, Klotzsch, & Otto, p. 38. t. 16). 
This Mexican epiphyte is surely the same as O. Rossi 
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 longé 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). It 
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. Benth. 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-
