of it), and the result brought its parent, with no more variation than 
constitutional or cultural conditions are capable of bringing about. 
With such clear results as these I, at least, cannot see where the appli- 
cation of ‘ Mendel’s law’ applies.”’ 
REVERSION IN Hysrips.—Mr. de. B. Crawshay instanced a case of 
reversion in Odontoglossum crispum X O.c. Crawshayanum. The flowers 
were crossed in 1895, sown in 1896, and bloomed in 1903. He added the 
following remarks: “A seedling raised from a fine Odontoglossum 
crispum @ crossed by O. c. Crawshayanum ¢, which has blotches on 
the sepals and petals, fin. long, of deep purple-brown. The seedling has no 
blotch or spot, save three extremely small ones in two of the four lips 
{four blooms). Absolute reversion has occurred, both in form and in. 
absence of blotch. The form is as bad as can be. Hence I deduce that 
my contention of years’ standing, that a true crispum is white and 
unspotted, has been proved by the first plant to bloom, which has reverted 
beyond all possible expectation. The blotching of a so-called spotted 
crispum is, I contend, the remains of hybridity. This, I consider, is, in 
some way of Nature’s own, acquired from O. luteopurpureum ; and as 
these blotches are therefore adventitious, they fail to transmit their 
characters to the resulting progeny—ergo, the spotted crispums are not 
pure crispums at all, but hybrids or crosses. See my article upon 
“ Reversion in Odontoglossums’ in the Gardener’s Chronicle, February 
14th, 1903.” 
CYPRIPEDIUM CROsSsES.—Specimens of Cypripedium xX Actzus were 
exhibited by Mr. J. Douglas, to illustrate the reversion of Orchids. C. X 
Actzeus was raised by crossing C. X Leeanum with C. insigne Sandere, 
the last-named variety being totally different from any other variety of 
C. insigne, as it lacks the large spots on the dorsal sepal. C. x Lee- 
anum was obtained by crossing C. Spicerianum with C. insigne Chantini, 
and the reversion consists in the fact that one variety of C. X Actzus 
was almost a replica of the original form of C. insigne Chantini, from 
which C. x Leeanum was produced. Many of the other forms—indeed, 
nearly all of them—might be described as good varieties of C. insigne. 
AT the meeting held on March 24th there was again a fine display of 
Orchids. 
N. C. Cookson, Esq., Oakwood, Wylam-on-Tyne (gr. Mr. Chapman), 
received a Silver-gilt Flora Medal for a magnificent group, consisting largely 
of hybrid Phaius, mostly varieties of P. x Norman, about three dozen 
plants being staged. The group also contained P. Sanderianus, a fine form 
of Odontoglossum x excellens, O. X Rolfeze Oakwood variety, having an 
orange-coloured crest to the lip, O. x Adrianz Doris, evenly spotted with
