flowered Cattleya with an entire lip, and one fourth from one of medium | 
size with a three-lobed lip, the three-lobed lip will persist, slightly modified 
in shape, and smaller size. 
A paper by Major C. C. Hurst, F.L.S., on The Principles of Genetics, _ 
includes some references to Orchids, particulariy albino Cattleyas and the 
origin of a scarlet Odontoglossum crispum, which have already been noted 
in our pages. There is also an interesting reference to self-fertilisation :— 
‘‘The fact of the existence of a certain amount of self-sterility in many 
Orchids makes breeding somewhat more complicated than in other plants. 
For instance, for several years I have been attempting to self certain 
segregates of Cypripedium Hera, and so far the only positive result 
obtained has been one plant raised from C. Hera punctatum, and an 
apparently good pod of seed now developing on C. H. Hurstii. More than 
150 selfings have given no good seeds.” 
The following *extracts are also significant :— 
How are Mendelian factors produced? That is the problem that now 
presents itself, and from the true solution of which we are still far distant.

For nearly forty years I have had opportunities of watching many 
thousands of plants under cultivation, and my own opinion, which is 
shared by my collaborators, is that there is nothing approaching a new 
species which has arisen by a mutation.—A. W. SuTTON. 
ODONTOCHILUS LANCEOLATUS.—A very distinct and pretty little Orchid 
of the Ancectochilus group has flowered in the collection of H. J. Elwes, 
Esq., Colesborne Park, Glos. It is a native of Sikkim, and proves to be 
the plant originally described by Lindley under the name of Ancectochilus 
Janceolatus (Gen. & Sp. Orch., p. 499), but which afterwards proved to 
belong to the allied genus Odontochilus, and was called O. lanceolatus, 
Benth. (Hook. f. Fl. Brit. Ind., vi. p. tot). King & Pantling, however, 
retain the original name (Orch. Sikkim, p. 295, t. 392). It occurs in Sikkim 
at 5000 to 6000 feet elevation, and is also found in the Khasia Hills. The 
leaves are green, and the flowers are borne in an erect spike about six 
inches high, the sepals aad petals being light green, and the lip bright 
yellow, with two obliquely-spreading front lobes, and a strongly-toothed 
claw. The anther is pink. The plant afterwards called Ancectochilus 
luteus by Lindley has proved identical. The difference from Ancectochilus 
lies in the lip having only a short sac, concealed behind the base of the 
lateral sepals, instead of a somewhat elongated spur. The large bright 
yellow lip gives the flowers a very attractive character. We do he find a 
record of the plant being in cultivation before.—-R.A.R.
