200 THE ORCHID REVIEW. 
lower flowers are equally abnormal, but in a totally different way. One 
consists of a single sepal and a second organ which can only be described 
as half a lip and half a petal joined together longitudinally, for the dividing 
line between the two halves is as sharp as if cut by a knife, one showing 
every detail of the lip in shape, the infolding of the side lobes, and the 
colour, including all the markings of the disc, while the other half is 
simply white and flat, like a petal. Even the column is Janus-like in 
character, the lip side having the characteristic wing and angle, together — 
with an imperfect anther and stigma, while on the petal side all these parts 
are absent. The lower flower of the other raceme hasa quite different half- 
and-half organ, in this case one side belonging to the dorsal sepal and the 
other to a petal, the different texture and shape being equally well defined. 
The other petal is united to the side of the column, and thus shorter than 
usual, and crumpled up. The column and lateral sepals are normal and 
the lip nearly so. Several other plants of C. Mendelii in this sportive 
condition are known (see vol. iii, p. 236, also p. 224; ii, p. 251; and iv. 
p- 128), but what is the cause we are unable to say. It is clearly some 
constitutional peculiarity, and, curiously enough, the flowers seem to be 
abnormal in different ways and at different times, and some of them are 
really very striking, as in the case of the one sent by Messrs. Hurst, which 
has large and brilliantly coloured flowers, and should be taken care of. 
The peculiarity recurs so frequently as to deserve the varietal name above 
proposed. 
BOTANICAL ORCHIDS AT KEW. 
AMONGST the most attractive botanical Orchids now in flower at Kew, are 
several very interesting plants which are certainly worthy of notice. 
In the Warm department two plants form a very pleasing sight; the 
remarkable Bulbophyllum barbigerum, whose curiously articulated lip is 
constantly in motion, and the handsome Grammangis Ellisii, a native of 
Madagascar, which bears a raceme of not less than twenty-three pretty 
flowers. The latter species is a warmth loving kind, and grows splendidly 
in baskets hanging from the roof. 
Another very interesting plant is the new Mystacidium angustum 
(Rolfe), a very free growing and flowering species from West Africa. 
Angrecum Scottianum has terete leaves and graceful white flowers. 
Ornithocephalus grandiflorus is very free flowering, and has remained in 
bloom for a couple of months. Another species, native of West tropical 
Africa, is Polystachya Adansoniz, with small greenish white and purple 
flowers. Hartwegia purpurea has purple flowers and leaves prettily 
variegated with green and brown. It seems to be very rare in cultivation.
