Thus, it is repeated and published in the very latest editions of standard works that South American Cattleyas, which will breed, not only among themselves, but also with the Brazilian Loelias, decline an alliance with their Mexican kindred. But Baron Schroeder possesses a hybrid of such typical parentage as Catt. citrina, Mexican, and Catt. intermedia, Brazilian.
It appears that of more than fifty species of these foraminifera described by D'Archiac, one or two species only are found in other tertiary formations whether of older or newer date. Nummulites intermedia, a Middle Eocene form, ascends into the Lower Miocene, but it seems doubtful whether any species descends to the level of the London clay, still less to the Argile plastique or Woolwich beds.
The first bi-generic cross deserves a paragraph to itself if only on that account; but its own merits are more than sufficient. Sophro-Cattleya Batemaniana was raised by Messrs. Veitch from Sophronitis grandiflora × Catt. intermedia. It flowered in August, 1886; petals and sepals rosy scarlet, lip pale lilac bordered with amethyst and tipped with rosy purple.
Reichenbach displayed his scientific instinct by suggesting that two species submitted to him might probably be the issue of parents named; since that date Seden has produced both of them from the crosses which Reichenbach indicated. We have three natural hybrids among Phaloenopsis. Ph. intermedia made its appearance in a lot of Ph. Aphrodite, imported 1852.
Macfarlane has discovered a natural hybrid between two species of sundew in the swamps near Atco, N.J. The parents, D. intermedia and D. filiformis, were growing abundantly all around, but of the hybrid only a group of eleven plants was found. A detailed comparison of the hybrid with its parents demonstrated a minute blending of the anatomical peculiarities of the parental species.
Some facts in regard to the colouring of pigeons well deserve consideration. The rock-pigeon is of a slaty-blue, with white loins; but the Indian sub-species, C. intermedia of Strickland, has this part bluish. The tail has a terminal dark bar, with the outer feathers externally edged at the base with white. The wings have two black bars.
Aphrodite with Ph. rosea, and proved it. Our garden hybrids are two: Ph. F.L. Ames, obtained from Ph. amabilis × Ph. intermedia, and Ph. Harriettæ from Ph. amabilis × Ph. violacea, named after the daughter of Hon. Erastus Corning, of Albany, U.S.A. Oncidiums yield only two natural hybrids at present, and those uncertain; others are suspected. We have no garden hybrids, I believe, as yet.
There are several forms of this pretty shrub, but as they do not differ to any great extent from the species, are hardly worthy of consideration. F. suspensa intermedia is a garden hybrid, 1891. F. VIRIDISSIMA. Japan, 1845. This is another desirable species, but it is not comparable in point of beauty with the former.
The drooping tea trees, which had increased both in number and size, grew in company with an arborescent Calistemon, along the water's edge; and a species of Eucalyptus, somewhat resembling Angophora intermedia, was discovered at this spot: it occurs frequently to the northward, and is common round the gulf of Carpentaria.
Three other less common forms might also be mentioned. P. Laurocerasus angustifolia, with narrow leaves; P. Laurocerasus camelliaefolia, with thick leathery foliage; and P. Laurocerasus intermedia, halfway between P. Laurocerasus angustifolia and the common Laurel. Portugal Laurel. Portugal, 1648. A well-known shrub or small growing tree, and one of the most valuable of all our hardy evergreens.
