Many growers are fully aware of these requirements, but others are not so well informed. _Masdevallias_ are free-growing and free-rooting plants, and are easily increased by dividing the tufts just as they are about to make their growth; but it must not be expected that these will flower well until they get established, which they will do best in small pots after being divided. The second year the growth will be stronger and as they get established larger pots may be given to them as required. Rough fibrous peat, sphagnum moss, and good drainage should be given, and the roots must be kept moist. Insects should be kept under. They are subject to attacks of green fly on their young growths and flower spikes, and of thrips on the leaves, which must be kept under, or the growth will be crippled. [Illustration: PL. 106. MAXILLARIA LUTEO-ALBA.] MAXILLARIA LUTEO-ALBA. [Plate 106.] Native of Colombia. Epiphytal. _Pseudobulbs_ large, about two and a half inches high, ovate obtuse, compressed, clustered, bearing at the apex a solitary leaf. _Leaves_ stalked by the folding of the basal portion, oblong obtuse, a foot long or more, of a dark green colour. _Peduncles_ radical, about half the length of the leaves, invested throughout with green sheathing bracts. _Flowers_ large and peculiar in form, triangular in outline, and measuring about six inches from the top of the dorsal to the top of the lateral sepal, brownish externally; _dorsal sepal_ linear-oblong, acute, three inches long, of a tawny yellow in the upper two-thirds of its length, the basal third white, _lateral sepals_ of the same form, size, and colours, but twisted; _petals_ two, erect, or somewhat projecting like two horns, ovate oblong, about half as long as the sepals, white at the base, with a few splashes of purple, yellow at the tip, with a blotch of pale brown of about equal size between; _lip_ concave at the base, hairy, the margins undulated, three-lobed, the lobes obtuse, the lateral ones short, erect, yellow, striped with purple, the front one oblong, emarginate, recurved, the central portion convex, yellow, the margins paler, whitish. _Column_ short, curved, creamy-white. Maxillaria luteo-alba, _Lindley_, _Orchidaceæ Lindenianæ_, 20; _Reichenbach fil._, in _Walpers’ Annales Botanices Systematiceæ_, vi., 516; _Id._ _Bonplandia_, ii., 15, 280. The _Maxillarias_ form a genus of Orchids not much appreciated by many growers, but of late there has been greater variety introduced among them, and they are becoming more popular in cultivation. Some of the better and more showy kinds are quite worth bringing before our readers, as they are free-growing plants, and most of them may be kept along with the cool Orchids.
