The following reply to an inquiry recently made is supplied from the Garden. We cannot learn that it has yet appeared in American gardens. It is Bouvardia flava. The flowers of this kind are of such an uncommon color, that one would expect to find it grown almost in every garden, but such is not the case; indeed, it is but poorly represented in even the large nurseries. It differs in no other important respect from the other varieties, except by the clear yellow color of the flowers, which are plentifully produced even on young plants. Another noteworthy variety we saw in Messrs. Veitch's, at Chelsea, was Rosea oculata, which has large flowers of a delicate blush hue and a conspicuous deep-tinted eye, which renders it a distinct and attractive plant. This variety occupies the greater part of a house, a fact which affords a proof of its popularity. Among other attractive sorts we noted were Maiden's Blush, a delicate soft blush tint, and is a free flowerer and of vigorous growth.
