cate, acute, pure white, the reflected apex — with green, the 
inner part thick and fleshy, the outer, especially towards the apex, 
reduced to a thin edge; below these, and rather less deeply sepa- 
rated, are two white, shorter segments, ofsimilar structure to them, 
but, from their thin edge being convolute, they appear like two 
parallel, nearly straight cylinders, distilling honey from their ex- 
tremities, and projecting downwards upon the surface of the cen- 
tral lobe, which is the longest of any, and is cleft into three long, 
green, linear, flexuose segments; while from its base, in the centre 
of the flower, rises ashort, white, blunt, slightly curved, cylindrical 
tooth, round which, and round the mouth of the spur, a fold of 
the perianth passes, connecting to each other the bases of the con- 
volute segments. The two lower segments of the outer perianth 
are connate at the base with the inner. Between the bases of the 
first and second portion of the labellum, there is on each side a 
short, broad, subcrenate, fleshy scale. Spur (an inch and a quar- 
ter long) blunt, flattened, nearly straight, shorter than the germen, 
green. Stamen green, cucullate, placed under the hood of the 
outer perianth. Pollen-Masses two, marginal, spathulato-elliP 
tical, flattened bi-parted, yellow, granular, on long, elastic p 
cels, which enlarge at their upper extremities, and arise from @ 
little adhesive scale, which, asin other Orcu1pE4%, attaching itself 
firmly to any body that is brought into contact with it, causes the 
pollen-mass to be readily drawn from the flower ; segments of the 
peace nae somewhat concave on their inner side, granules large, 
oose, and attached only to the outside of the segment, Anther- 
cases greatly attenuated at their bases, projecting forwards like 
two teeth in the middle of the flower, partly covered by the re- 
flected edge of a white, ciliated cucullus, which rises in front of 
the anther-case, and is much larger than it. This investing fold 
of its edge passes backwards, and terminates on each side in the 
fleshy scale, between the base of the first and second segments 0 
the labellum. Germen (about two inches long) longer than the 
spur, green, twisted, unilocular. Ovula minute, very numerous, 
white, naked, forming two waved lines nearly the whole length of 
the germen, on each of three parietal receptacles. 
his rare plant, the solitary species of a genus presenting a very 
complicated form of flower, is a native of the Cape of Hope- 
Here, and I suspect in other cases among the Orchidew, the sud 
den abstraction of the pollen-mass, by the adhesion of the scale at 
the base of its pedicel to the finger of the examiner, has give? 
rise to the belief that it starts out from an elastic power. The pedi- 
cel, when forcibly extended, contracts from elasticity, but never 
forces the pollen-mass from its case, otherwise than by dra 
it after a substance to which the scale at its base had adhered. 
The specimen described was kindly communicated to the Royal 
Botanic Garden, Edinburgh, by Mr. Arron, from the rich collec 
tion at Kew, in 1826. It has been always kept in the stove, I 
soil containing a large proportion of peat, and flowered very 
freely both last year and this in March and April. The flow’ 
remain expanded for a considerable time. Graham.
