The dragon arum, dragon root or green dragon, is the native Arisaema Dracontiian. The dragon plant of Europe is Dracunculus vulgaris. The dragon's head is not an aroid, but a Dracocepha-lum, a genus of mints. False dragon's head is Physo-stegia. The dragon's blood of commerce is a dark red, astringent, resinous secretion of the fruits of a palm,
Other kinds of dragon's blood are produced by Dracaena Draco and Ecastophyllum monetaria (now referred to Dalbergia). "Sticks," "reeds," "tears" and "lumps" of dragon's blood are known to commerce. The resin is used in coloring varnishes, dyeing horn in imitation of tortoise shell, and in the composition of tooth-powders and various tinctures. The dragon tree is Dracaena Draco.
(Greek, wood and tongue, of no direct significance). Polypodiaceae. Small ferns, 5 to 10 species, occurring wild in both tropics, with wide creeping rootstalks, and small, entire leaves: sori resembling those of Polypodium. None is advertised in Amer. Three or 4 kinds are mentioned in horticultural literature abroad, but are not cultivated here. l M. Underwood.
(Greek, oak-like). Polypodiaceae. Some 10 or more E. Indian ferns, with round naked sori, as in Polypodium, but with a fine network of netted veins which are arranged in distinctly rectangular meshes. The most distinctive feature is in the shape of the leaves which are either of 2 sorts, as in Platycerium, the cup If. having the shape of an oak If.; or the base of each If. is separately lobed and oak-like. D. quer-cifolia, with 2 sorts of leaves, the spore-bearing 2-3 ft. long, is the commonest species. D. rigidula, Swartz (D. diversifolia, R. Br.), a similar but larger species from the same region also appeared at one time in the American trade, but the species are seldom seen in cult, in this country. D. musaefolia is occasionally seen in fine collections, where it is grown for its striking simple foliage, which reminds one of the bird's nest fern (Asplenium Nidus). It is really a Polypodium, which see for description. r c. Benedict.†
(probably from Greek for drupe, from the character of the fruit). Guiana Plum. White-wood. Euphorbidceae. Tropical evergreen greenhouse shrubs. Glabrous: leaves leathery, alternate, simple, mostly entire: flowers dioecious, in axillary clusters or pistillate single, apetalous, staminate flowers with calyx imbricate and a rudimentary pistil; stigma broad, nearly sessile; pistil 1-celled, 2-ovuled. - About 10 species in tropical Amer., 2 native in S. Fla. They do well in light loam. Prop, from cuttings in sand with heat. D. lateriflora, Urban (D. crocea, Poit. Schaefferia lateriflora, Swartz), of W. India region, 6 ft. high, leaves elliptical, pointed, has been in cultivation j, b. S. Norton.
(A. N. Duchesne, monographer of Fragaria in 1766). Rosaceae. Fragaria-like perennial trailing herbs, differing in the calyx being 5-parted and the lobes alternating with larger leafy 3-5-toothed bracts, the petals yellow, and the receptacle dry and spongy rather than becoming fleshy or pulpy as in the strawberry: leaves ternate, with short-stalked leaflets: flowers solitary, on the runners; stamens 20-25, short. - Two species in S. Asia, one of which has run wild in this country, and is useful as a basket-plant and as a low ground-cover.
Focke (Fragaria indica, Andr.). Yellow Strawberry. A neat plant trailing close on the ground, with leafy runners, pubescent: lfts, rhombic-ovate, more or less petioled, coarsely crenate, obtuse: flowers about 3/4in across, on peduncles equaling or exceeding the leaves: fruit usually less than 1/2in. diam., red, insipid. In waste grounds, N. Y., west and south.
