their beauties of form and colour, but in the flower tent such a glorious and gorgeous effect as that produced by Mr. Bull’s display is never realized. We could say much more in respect to this Exhibition, but space will not permit.—B. S. W. [Illustration: PL. 105. MASDEVALLIA HARRYANA ATROSANGUINEA.] MASDEVALLIA HARRYANA ATROSANGUINEA. [Plate 105.] Native of New Grenada. Epiphytal. _Stems_ slender, short, tufted. _Leaves_ persistent, leathery in texture, with a nerveless elongate oblong-spathulate obtuse or somewhat acute blade, which is channelled at the base, keeled behind, of a dark green colour, narrowed downwards into a short petiole, three to four inches long, grooved in front, and invested at the base by long membranous brownish sheaths. _Scape_ erect, about a foot high, striately pencilled with purple, furnished with a few appressed sheathing bracts, bearing a solitary flower at the top. _Flowers_ richly-coloured and strikingly handsome; _tube_ a quarter of an inch wide and three-quarters of an inch long, dull orange-yellow stained with rosy purple in front, the mouth more closed than in some other forms; _dorsal sepal_ upwards of two inches long, narrow nearly to the base, filiform upwards; _lateral sepals_ deflexed, broadly and obliquely flacate-lanceolate, acuminate, two and a half inches long, and nearly an inch wide, of a rich glowing crimson flushed with magenta; _petals_ and _lip_ small, hidden at the base of the tube. Masdevallia Harryana atrosanguinea, _Hort. Williams_. Of the genus _Masdevallia_ a few years ago there were but a very limited number of species known in cultivation, but it is now becoming a very comprehensive one, thanks to the perseverance or our energetic collectors, who have striven hard to bring the plants home, and have in a great measure succeeded, although with many of them the task of importation has been very difficult.
