Genus Thuja, Linn., and of the Xortli American Species of the Genus Z,z6o-
cedrus, Endl." in its passage through the press. At page 363 of the volume
in which it is contained (Trans. Bot. Soc. Edin. ix.), the parallel columns
containing tlie characters of the two genera should be transposed, and the word
" the," fifteenth line from foot of p. 362, last word in the line deleted. This
error is evident both from the context and the preceding and following matter,
but as it stands is apt to be confusing.
Dr. Masters lately exhibited, at a meeting of the Scientific Committee of the
E.oja! Horticultural Society, a specimen of a monoecious Mistleto, sent by
Mr. George Thomson, gardener at Stansted Park, Sussex. The same main
trunk bore short, stiif, compact shoots, with small leaves of a dark green colour,
and ripe berries, and, at the same time, long, slender, pendulous, whip-like
slioots, with larger yellow-coloured leaves, and perfect male flowers in full
bloom. Dr. Masters stated that he had never before seen or heard of a similar
instance in the Mistleto, though analogous cases in other ordinarily dioecious
plants were not unfrequent. Professor Oliver, who had paid much attention
to tlie LoranthacecE, had also informed Dr. Masters, that he had not seen any
record of monoicism in the Mistleto, though such a condition was common in
some of the other genera of the Order. Professor Oliver also remarked that
the present case was the more remarkable from the fact that the sexual cha-
racteristics of Mistleto are usually, so well marked that it is possible to distin-
guish the male from the female plants at a distance by their colour or general
aspect. It was suggested by some members of the Committee that tliis might
be a case of natural grafting, owing to a seed having fallen on the male plant,
and there germinated—a parasite on a parasite!— but tliis view of the case was
not borne out by a section of the branch.
Mr. Wilson Saunders, at the same meeting, exhibited a Hyacinth of the
variety called " Robert Steiger," in which the flowers, instead of being of their
usual carmine colour, were all green. The diiference in colour was associated
with still more important variations in forrii and direction, the flowers having
aU of them an elongated tubular form, and an erect direction. It was stated
that the anthers were of a pink colour, and somewhat deformed. The Hyacinth
in question had been grown imder precisely the same conditions as others
which were unaffected. Mr. Berkeley alluded to similar instances of vires-
cence or phyUomorphy in Colchicum autumnale, and Dr. Masters to the like
phenomena in some species of Convallaria.
