The gemmse bearing learea occupy the middle of the stem, which is interrupted on account of them ; they are usually orate, subentire and sabtruncate at the apex, and closely wrapped about the stem.

Sandwich Islands. Communicated by Dr. H. N. Bolander, (1865.) A neat and pretty little plant, about the aise of Lyeunia lerpylli/olia ; the form of the leaves suggesting a Ptagioehila, but the general appearance of tbe plant is ttill more suggestive of a Saeeogyna, and, indeed, I am not sure but that it oiigfat rather to have been referred to this latter genua than to Ovmnam- THi. The cella of the leaves are very large and loosely arranged, and are usually furnished with broad and short projecting points. They also vary greatly in size and position, being roundish or oblong, and frequently some of them are obliquely or even transversely disposed through tbe leaf. Those on the margin are usually narrower than the others, and vary from subquadrate to elongated-oblong or parallelogrammoid. The cells of the stem are also very loosely disposed ; however, they are still larger than tbe leaf-cella, and uniformly oblong.

Sandwich Islands. Communicated by Dr. H. N. Bola-idcr, (1H05.) A neat and pretty little species. Possibly too near the Mexican C. laxa, L, ^ O., .STjm. /ftp. p. 713, but nothing is there said about the flagiliferous ramification, a striking feature of our plant; and thv leaves are said to be lax and minuttt^ bidentate, characters which do not agree with our plant, whose leaves do not change their shape in drying, and, for the genus, are pretty strongly toothed. The peculiar bifurcation of most of the ampbigaslria, and the transverse elongation of the marginal cells of the leaf, appear to be generic characters (specifle only in degree), as they occur (in a less degree) in C. 7V«> cMomanu, and at least in two other species.

To the naked eye the dried specimens look like little beapi of some fila- inentose conferva. In this state the frond is very brittle, and, on account of its loose texture, appears to be deeply pitted and fibrose and papulose above. Upon moistening the specimens the fronds become tongh (much as in the Anihoeerotea), the upper surface looses its pitted appearance, and the inter- stices (apparent fibres) between the large cells close up ; and the fruit, which was completely hidden before, now appears as a black spot in the substance of the frond. Upon re-drying the specimens the fVonds become much thinner than they were at first, and the fruit remains visible, protruding ttom the upper surface. The frond is larger than in Sphteroearpu* Miehtlii, from the Southern States, but lobed and reticulated in tbe same manner. The extreme apices of the lobes are often suddenly contracted and subsolid (much as is often seen in the AntkoreroUai.)

They are suborbicular in outline, lobed and rooting underneath, as in the true terrestrial species. They also have rudimentary scales at the apices of the lobei nuderneath. These fronds become immersed by the au- tumn rains, and during the winter the apices of the lobes thiclcsn and expand greatly. These apices being destitute of rootlets and extremely buoyant, gradually assume a vertical position in the bottom of the pool, and at length (in the spring) become detached and rise to the surface of the water, (where they float in « horisontal position,) often carrying with them porticos of the effete base of the frond. In the meantime the scales develop into long purple fringes. Tktn floating apiett alvne eonttitule th« L. natan* of Linnteut and author* : (vide Aust. Hep. Exsi^ N. 144, A. ; also Lindbg.

Sometimes the autumn fVonds do not become immersed, in this case they remain whole ; again the fertile fronds are often left upon the mud by the dessication of the pool in summer ; in this case they are plainly continuous flrom the apex: (vide Hep.

A single fVond only of this species was found by me iu Sept. 1858, at Oloster, It. J. This flrHttd'edntained a single sporangium I which is about as in R. erjfttallina. The spores are also as in that species. During the past eight years I have not only watched this i>lant in all the stages of its growth, fVom the time of its first appearaace in the month of June, until its final disappear- ance in winter, but have collected many specimens of it in the mature state. I have also received numerous specimens of it from many localities, from New England to Canada and Missouri ; but not a single one of tbesv) speci- mens shouB any trace either of f^uit or other kind of reproductive organ whatever I and it is still a mystery how the plant reprodnces itself. The . young plants make their appearance in great profusion, in the bottoms of exsiccated ditches, kc, in the beginning of summer. These rapidly develop into the sterile plant, which has been most accurately described and figured by Mr. Sullivant : (ifem. Amer. Aead. Arte if Set. (Boston) 4, p. 176, t. 4.) No rootlets are produced underneath the frond abcve the middle ; and astheditches become filled with water late in autumn, the fragile lacinin break asunder near the middle, in consequence of the extreme buoyancy of their apices. The detached pieces (or apices) rise to the surface of the water, where they re- main suspended in ai| oblique position (the extreme apt* only reachiu~ the surface), until ttiey become frozen up in the ice. Upon the ice disap- pearing in the spring, no trace of any portion of the plant is to be found I ^■;"5 ■*».jjjimj>i»iii'*- '7>rjm. ■■^i^5a»iS*te*j«*ria»563Bei^!ifai!S.i^^ ■^!„iiu.^,.i\- ^
