Sir J. Banks and Dr. Solander it would appear were amongst the original discoverers of this species, though it is of so general occurrence throughout many parts of the tropics, as very probably to exist in some of the older Herbaria. Forster's name seems to have been entirely overlooked by botanists; it is attached to a specimen, preserved in the British Museum, of the plant now well known under the name of L. Jussieui Desv., a very widely diffused species, especially throughout the S. American continent. Mr. Colenso has collected it in the mountainous interior of the northern island of New Zealand, and Sir J. Banks and Dr. Solander in Admiralty Sound. There exist, in Herb. Hook., South American specimens from as far south as Valdivia, and also froin Peru, New Grenada, and Jamaica, where it appears to be abundant, varying slightly in habit, being sometimes suberect or ascending, but more generally having a long trailing caudex, which sends up erect branching stems.

The L. scariosum belongs to a small section of the genus, whose natural position is between the two great groups, namely, that with the leaves imbricated all round the stem, and that in which they are stipulate, distichous, and more or less of a membranous texture. The spikes of this section are generally pedunculate and often branched, as in this species and L. complanatum, L. ; but sometimes sessile, which is the case with L. decurrens, Br. ; in the former character, as in the coriaceous fobage, often indistinct stipules and arctic, alpine or temperate habitats, this section differs from the tropical distichous-leaved division to which the form of foliage approximates it. Like most natural groups, the limits of this cannot be very strictly defined ; Mr. Brown's L. decurrens has the sessile spikes of the tropical species of Selaginella and some states of L. complanatum ; approaching forms of L. Alpiwum, D., pass into the imbricated ones. The allies of L. scariosum are few ; I am acquainted with the following ; 1. L. decurrens, Br., only known as an inhabitant of the Alps of Van Diemen's Land ; 2. L. complanatum, L., this is a very widely diffused plant throughout the temperate and arctic regions of Europe, Asia, and America; we possess specimens of a very similar, if not the same species, from upper India and the Peninsula of Hiudostan, as also from Jamaica, from Mexico, Columbia. Peru, Caraccas and Brazil, it is the L. thuyoides, H. B. K. ; 3. L. volubile, Forst., a very common New Zealand species this and the two following have compound panicles of spikes, with elongated and spreading branches ; 4. L.flicaule, (vid. infra) ; 5. L. comans, (vid. infra) ; 6. L. V'iyhtianum, Wall., some states of this have the leaves towards the
