5. Barkeri, Mexico, dull white, February to December. These require to be kept rather dry and cool in the winter season. No. 5. may be had in flower all the year, by having several pots, and keeping them dry at different periods. Early in spring the tubers may be potted in 6 in. pots, in a soil composed of well-decayed leaf mould, loam, and sand. They require little water till the leaves appear, when they will take an abundance. They may be forwarded in a little heat, but will do pretty well if allowed to come along with the season. They are easily propagated from their tubers, by cuttings, or by seeds. SHRUBBY OR FIBROUS ROOTED. 1. B. nitida, native of Jamaica, with pinkish white flowers, and large, thick, shining leaves. May be had in bloom all the year, and made into handsome specimens. 2. B. spathulata, another West Indian, with a very erect habit of growth. The leaves are folded in like spoons, and the small white flowers appear at the ends of the young growth. It flowers from August to December, and is but an average kind. 3. B. odorata, a Brazilian kind allied to the last, but has a fine foliage, resembling nitida, the flowers came out like the last from August to December, are much larger and sweet scented. 4. B. hirtella, a Brazilian species, with a rather starved looking habit of growth, but an abundance of small, pinky white flowers, appearing from June to December. 5. B. ulmifolia, a South American, with elm like leaves, but of no great beauty of flower. Only desirable to form a collection. 6. B. argyrostigma, a Brazilian species, with curiously spotted leaves, which is its chief attraction. The flowers appear from June to December. It is a very strong grower—occupies much room. 7. B. hydrocotylifolia, a Brazilian pretty species. It is herbaceous, or has its leaves from a rhizoma creeping on the surface. Its pink flowers, borne on scapes about a foot high, appear from February to May. 8. B. parvifolia, a native of the Cape of Good Hope. It has very small leaves, grows about 2 feet high, and is always in flower. A white flowering and desirable kind. 9. B. albo-coccinea, a West Indian. Its oblique leaves are almost round, are very large and thick, and of a deep red beneath. The flowers appear from February to May; white on the inside, and scarlet on the back. The best of the rhizoma producing kinds. 10. B. nomonyma, a Brazilian species, in the way of B. manicata, with small white flowers, continuing from July to November. 11. B. castaneæfolia. The specimens that I have seen growing are so like B. ulmifolia, that I have either not seen the true species or they are both the same. 12. B. Fischeri, a rather scarce Brazilian species, but one of the most desirable, approaching B. incarnata. In the spring months it is covered with its numerous pink or white flowers. 13. B. incarnata, a South American, that should be No. 1 in all collections. Its pink flowers may be had nearly all the year.
