SALVIN1A (named in honour of Antonio Maria 

 Salvini, a Professor at Florence in the seventeenth cen- 

 tury). OBD. Salviniece. A small genus (all the supposed 

 species are reducible to one) of plants found floating 

 on still water (like Lemna), broadly dispersed over the 

 Northern hemisphere, and in tropical and South America. 

 " This pretty little floating aquatic, which, like Azolla, is 

 suitable for a stove, greenhouse, or indoor aquarium, is 

 easily managed in the summer time, simply requiring to 

 be let alone or have its water changed, if necessary ; but 

 in the winter is often lost through a want of knowledge of 

 its life-history. The mature plant floats on the water, 

 and has no true roots, though the row of divided leaves on 

 the under side of the stem look like roots at first sight, 

 and assume their functions. Among these the spore 

 capsules are developed, and from them the plant must 

 be grown annually, as the old plants die in the winter. 

 The best way to preserve the spores is to half fill a 

 broad pan with sandy loam, and then fill up with water; 

 when the water has cleared, place a number of plants 

 upon it, and stand the pan by in a cool greenhouse. In 



Vol. 111. 



Salvinia continued. 



the winter, the plants will all die, but the spores will 

 remain in the loam, which must not be thrown away or 

 allowed to dry, and the next spring they will reproduce 

 the plant" (N. E. Brown). 



S. natans (floating), fr. consisting of globular bags, composed 

 of a double membrane, at lenath bursting irregularly. I. Fern- 

 hke, sub-^Uiptic, entire, floating, not curled up when voung 

 Rhizome floating, thread-like, leafy above, and furnished' below 

 with long rootlets and fruit on short, leafless branches The 

 young plant closely resembles a young Selaginella, apart from 

 the two cotyledon-like processes. 



SALVINIEJB. A small natural order of annual, 

 floating herbs, not attached to the soil, resembling large 

 Lemnaa (Salvinia) or a Jungermannia (Azolla), with no 

 true stem. Salvinia is met with throughout the Northern 

 hemisphere, as well as in tropical and South America; 

 and Azolla, the only other genus, inhabits Asia, Africa, 

 Australia, and America from Canada to the Straits of 

 Magellan. Fronds with margins reflexed before expan- 

 sion, usually claret-coloured on the under surface, some- 

 times composed of cellular tissue, without nerves and 

 stomata (Salvinia) ; sometimes with a stomatiferons epi- 

 dermis (Azolla), rounded or lobed, sessile or sub-sessile, 

 alternate or distichous, imbricated. Reproductive organs 

 of two kinds, similar to those of Marsileacece, inserted at 

 the base of the fronds. The order embraces about 

 eighteen species. 



SAMARA (of Swartz). A synonym of Myrsine 

 (which see). 



SAMARA. An indehiscent fruit, producing a wing 

 from its back or end; e.g., the fruit of the Maple. 



SAMAROID. Resembling a Samara. 



SAMBUCUS (the old Latin name used by Pliny, 

 and derived from sambnke, an ancient musical instru- 

 ment, supposed to have been made of Elder-wood). 

 Elder. SYN. Tripetelus. OBD. Caprifolincece. A genus 

 comprising ten or twelve species of mostly hardy trees, 

 sub-shrubs, or shrubs, rarely perennial herbs; they are 

 dispersed over all temperate regions (South Africa ex- 

 cepted) and tropical mountains. Flowers white, yellow, 

 or pinkish, small, with articulated pedicels, disposed in 

 umbelliform corymbs or dense-flowered thyrses ; calyx 

 tube ovoid or turbinate, the limb equally three to five- 

 lobed or toothed ; corolla rotate or rotate-campanulate, 

 equally three to five-parted, the lobes imbricated or 

 rarely valvate ; stamens five. Drupes baccate, containing 

 three to five one-seeded stones. Leaves opposite, impari- 

 pinnate ; leaflets serrated or laciniated, naked at base, 

 glandular or augmented by a stipnliform leaflet. 

 Branches rather thick. Two species, S. Ehulus and 

 S. nigra, are indigenous to Britain. The berries of the 

 latter are largely employed in the manufacture of Elder- 

 berry wine. Various kinds of medicine, cosmetics, &c., 

 are obtainable from several of the species. Speaking of 

 the common Elder, Evelyn remarks: "If the medicinal 

 properties of the leaves, bark, berries &c., were thoroughly 

 known, I cannot tell what our countryman could ail for 

 which he might not fetch a remedy from every hedge, 

 either for sickness or wound." The species in cultivation 

 are described below. They are all hardy, and are of 

 very simple culture, thriving in almost any soil or 

 situation. Propagation may be effected, in the case of 

 the herbaceous species, by division; the shrubby kinds 

 increase readily from cuttings. The common Elder fruits 

 abundantly, if the soil be kept somewhat moist; its 

 position should be an open one, fully exposed to 

 light and j&ir. A plantation or hedge may be readily 

 formed by cuttings of this species, where the soil is 

 tolerably moist. The Golden Elder (S. nigra aurea) 

 is a fine ornamental plant for shrubberies, or for use in 

 snb-trcpical gardening. If the young shoots are regularly 

 pinched at their points, the plants may be kept dwarf 

 and of a tine golden colour all the summer.
