Welwitsch and Mettenius considered this fern should rank as a distinct speries. Welw itsch separates it because the fronds are impari- pinnate to the apes ; bhe pinnee are distinctly petiolate, and a bulbil is found at the base of the last pinna. The pinna; of the upper part of the frond are Bubsessile ; they have in the barren frond long acumi- nate apices, while the pinme of the fertile fronds are three or four times narrower, and shortly acuminate. In all essential characters this plant so closely agrees with A. punc- tatum that it seems to deserve a place only as a variety of that species. 6. A. Afzelii.

Julianum, which is common in Portugal, only in its somewhat more acute leaves, with nerve usually vanishing at two- thirds the leaf's length and not just below the apex, and in its rather larger capsule. The African plant has its older stems compressed, almost complanate, nigrescent. He observed the operculum of several capsules to be not conical but depresso-hemispherical, its rostrum becoming more equally cylindrical and not conical at the base ; but after examining more than twenty capsules in different stages of ripen- ing, he was constrained to modify his view as to this variation of form or proportion, the normal operculum being formed almost or indeed exactly as in 0. Julianum. 22. RACOPILUM Pal.-Beauv. Prodr. p. 36 (1805). Rhacopilum C. Muell. et aliorum. 1. R. tomentosum Brid. Bry. Univ. II. p. 719 (1827). ffypnwm tomentosum Sw. Prodr. p. 141 (1788); Hedw. Muse.

The firm yellow cell-walls distinguish our plants from such allies as Neckera Moritzii C.

Common, but seldom bearing fruit, on the ground or at the foot of old trees in forests between Lopollo and the Moniuo river : with fr. end of Dec. 1859. No. 36. This species is very closely related to R. variegatwn in the shape of the leaves and the peristome ; but appears to be sufficiently distinct in the glistening uniformly green colour, pinnate ramification, longer branchlets, more erect leaves with more delicate less distinct cells, and longer capsule. In R. variegatum the nerves and cell-walls of the leaves are lutescent, and the cell contents are contracted into a thin sinuate more or less evanescent thread. :;. R. physaophyllos.

No. 100. This species is less robust than R. chrysotis Broth. [Engl. Bot. Jahrb. XXIV. ii. p. 275 (1897)], and is of a brighter and more uniform green colour : but in that species it appears to find its nearest ally. In the theca there is a close resemblance, but Duby found no cilia in the peristome. The leaves of Welwitsch's plant are more crowded, less spreading, shorter, longly acuminate, with margins usually recurved, with two very short nerves, and alar cells four instead of six, and not forming an auricle.

STEPHANI If these plants, collected by Welwitsch in Angola, had been examined twenty years ago, the greater part of them would have been new to us ; since that time, however, a great many Hepatics have come in from Western Tropical Africa, particularly from from the islands of St. Thomas and Fernando Po, as well as from the neighbourhood of the Cameroons Mountains, so that only eight new species remain, the descriptions of which are here inserted. As to the geographical description of the following Hepatics, there are some amongst them which have been found in all tropical countries, as EvXejmniaJlava Spruce, Frvllania squarrosa Nees, Dimiortiera hirsutu R, Bl. et N., Cyathodium cavemarum Kunze, Aneura pinguis Dumort., and Anthoceros communis Steph. ; others belong to the flora of tropical South America, like Lopholejeunea Sagrceana Spr., Cololejeunea crenatiflora Steph., and Symphyogyna brasiliensis Nees. Quite a number have been found also at the Cape : for instance, Lejeunea Breutelii, L. Pappeana, Ricciella Rautanenii, and Plagiochasma muricata. What remains is entirely of African origin ; and the most interesting specimen is Exormotheca pustulosa, formerly known from Madeira and Teneriffe. Recently a new species of this genus has been found in Eastern Tropical Africa ; so that it may safely be considered a tropical genus of that continent.

Capsules arising from the margin of the frond, procumbent, from a very small conical inserted bulb cylindrical, acuminate, obtuse, ascending in a curve, with walls thick, formed of short very incrassate cells ; stomata none. Spores 34 /x, flavescent, smooth ; elaters a little smaller than the spores, with the spiral fibre reduced to three lamella? which run round the wall meridionally. Anthers unknown. Involucre large, 3- or 4-winged superficially with minute lamella?, especially rough on the wings. PUNGO Andongo.— Velvety green, flabellately applied to the ground in swampy places, which were becoming dry, between Condo and Quisonde, at an altitude of about 3000 ft. ; with perfect fr. 12 March 1857. No. 232. The plants are very crowded in growth, the younger fronds running over the old ones in all directions ; they are very thin at the base and stout and fleshy in the upper part of the frond ; the margin bears numerous small and crisped lobes, particularly about the growing point, which lies safely buried under them, in the deep cleft of the apex. This species is a near ally of N. decurva Mitten, and differs from that species in the size and thickness of the frond. The size and sculpture of the spores of N. decurva are not stated by the author. 2. N. flabellata Steph. sp. n. Anthoceros flabellatiis Welw. ms. Monoicous. Plant very large, densely stratified, green at apex, elsewhere flavo-rubescent. Frond up to 3 cm. long, repeatedly furcate, with the forks very thin (3 to 4 cells thick), with the margin remotely pinnate ; pinna? small, minutely pinnulate ; the whole frond exceedingly irregular, as though coarsely lacerated, formed of large cells, without cavities. Capsules solitary or in pairs, arising from the margin of the frond, which is always inno- vated from the base of the involucre, small ( 1 mm. long), clavate, with a large inserted basal bulb ; involucre smooth, very thin, of oblique growth, completely enveloping the capsule, as in the other members of the genus. Valves formed of very long, very in- crassate and very fragile cells; stomata none. Spores small (25/x), under the microscope brown, minutely rough. Elaters very short (28 by 34/a), more than twice as large as the spores, sub-hyaline, bispirous, with the spirals laxly coiled. Anthers solitary? in a large cavity.

They are chiefly from the latter region, bul a t'rw are From B nguella and Sierra Leone. The specimens are all dried ones, and for the mosl pari are mounted on paper. Por- tions of all had to In- MKiknl out tor invest Ration, the results of which have been verj gratifying, as bj this means, after a detailed examination, many of the smaller species bave been observed. These latter, however, bad not been collected as such, but, inde pendently entangled among other conspicuous species, had been collected with them. The Desmids bad practically .-ill been unconsciously obtained In this way, few, if any. collections having been made from places in which one would expect bo find Desmids in abundance; and yet about 130 fine species (including fifty undescribed ones) have been found as intruders amongst other algse. From these mere samples one is 1 « * I to wonder as to the richness of the Desmid-flora of Tropical Africa. Y. py little is known concerning the Freshwater Algse of Africa, only a few small scattered papers having as yet been published; and this extensive collection — one in which almost all the groups an- represented very considerably enlarges our knowledge ol the geographical distribution of these plants. At the time these algse were collected the great majority of the species were as yet undescribed. They form pan of the Welwitsch collection deposited in the British Museum, and the numbers after the species refer to the numbers on the 3b this collection. A few of the species can hardly be considered as freshwater ones, but as they were in the collection we bave included t hem. It is mi. resting to note that the earliest collection of algse made in Africa has been found bo be more extensive and representative than any hitherto described.

This may well be taken at first sight for a Lemanea with very- numerous nodes, the short lateral branches which clothe the axes of the filaments being so very dense and of such uniform length that a surface view appears almost parenchymatous.

This very beautiful species is characterized by its numerous elongate and delicate branches, which bear the short uniform lateral branches evenly without interruption along their whole length. The globose clusters of lateral branches, which are developed on every 7th to 12th node, are no doubt connected with the fructification ; their terminal cells are of a different form from the others, being larger and mostly subglobose. The axis of the filament does not pass through the centre of this dense mass of branches, but the attachment of the globular mass is at one side of the node from which they arise. 4.

It re- Bemblea the former in it- elongate form, in being but slightly con- Btricted m the middle, and in possessing a circular (or very Dearly circular) vertical view ; it differs from ii. however, in the absence of the deep linear notch at the apex, in the presence of a Bpini apical angle, and in the general conformation of the upper half <>f the semicells, which are somewhat wed^e shaped, with convex surfaces. From Euastrum it differs in its very slight constriction, its more parallel sides in front view, and in its circular vertical view. The cell membrane appears t<> he much less firm than that <>f a Tetmemorus. The punctulationa on it are in .-(.me -p., and in other- distant from each other, and occasionally the] well developed at the apical angles as to give them a faintly rough appearance. In one example the spine at cue df the apical angles was duplicated, the two spines being placed close together, and of differenl lengths. [t also approaches the genus Triploceros, bul the delicate character of tlie membrane, which is also destitute of warts, and the Bomewhat different apex distinguish it. 8. TETMEMORUS Half- (1844). 1.

This species has about twenty-five very short spines on each of the three angles of a semi-cell, over which is placed a pair of slender, erect and longer spines. It most nearly approaches S. Welwitschii in form and arrangement of spines, but differs from it in being triangular in vertical view, and in having a pair of slender erect spines in place of the single stout spine of the latter species. The angles are also furnished with more numerous and shorter spines, and it is moreover a smaller, much more constricted species. Var. pulchrum W. et G. S. West in Journ.

S. trihedrale var. rhomboideum W. et G. S.

Improving on this suggestion, Kiitzing, according to the reference on p. 206 of his " Species Algarum," establishes the genus Urococcus of Hassall ; but it cannot be held to constitute publication of a new genus, and, if Urococcus is to stand, it must be as Urococcus Kiitz.

In this genus the spores are produced from the ordinary vege- tative cells of certain of the plants. They are formed from the majority of (or even all) the cells of both the primary filaments -and branches of some portions of these plants, and have always thick yellowish-brown cell-walls. The outward form of the spores varies with the different species, the dimensions being about those of the vegetative cells. (Cf. also Hansgirg in Oesterreich. Bot. Zeitschr. xxxiv. 393 (1884); West in Journ. Linn. Soc. xxx. 272, pL xv. f. 23-28.) In most of the species the branches arise at right angles to the main filament, and the cell of the main fila- ment directly under the branch projects slightly into the sheath of the latter. 1.

[Scytonema having parallel margins with long cells, others having firm irregular margins with somewhat torulose trichomes, consisting of very short transversely elliptic cells of irregular size. The latter filaments much resemble the branches of a Stigonema. The sheaths of this plant are altogether remarkable, being quite colourless, and often very irregular in the margin ; wherever they come in contact with each other they appear to coalesce, and this coalescence gives rise to a phenomenon (viz. the apparent inclusion of two parallel trichomes in the same sheath) which, so far as we are aware, has not been previously noticed in this genus. The branches are also most peculiar, the majority being solitary, and given off laterally from one cell of the primary filament precisely as in Hapalosiphoh. Taking into consideration all these points, there are still unmistakable characters which place the plant in the genus Scytotiema. 2. TOLYPOTHRIX Kiitz. (1843). After examining the three following species, we cannot agree with Bornet and Flahault in separating the genera Ilassalia and Tohjpothrix. The former is said to be distinguished from the latter by its fragile filaments and its terrestrial habit. The three species referred to are all terrestrial as described for IfassaUia, but the sheaths (especially that of T. crassa) are very firm, persistent, and flexile, agreeing with those of Tohjpothrix. Under which genus ought these species to be placed ? The terrestrial habit points to Hassattia, the flexile and non-fragile filaments to Tohjpothrix. It appears to us that the only character left to separate the two supposed genera is the fragility of the sheaths, which in itself is certainly an insufficient generic distinction. 1.

This genus must be placed in the Lyngbyece on account of the structure of the sheath, which contains a solitary trichome. The com- parative width of the sheath, its hyaline character with irregular margin, along with the peculiar habit of the plant, characterise the genus. The younger plants (consisting of short filaments of 12-20 cells) are endophytic, occurring between the lamellae of the sheath of Porphyrosiphon. As they increase in size they appear to break through the outer lamella? of the sheath of the host, and to attach themselves closely to its outer surface by means of their own mucous envelope, which is nowr considerably broader. 5.

Welwitsch contributed to the Journal of Travel and Natural History, vol. i. pp. 22-36 (1868), a paper entitled "The Pedras Negras of Pungo Andongo in Angola," in which he shows that the prolific growth of a subaerial alga is the cause of one of the main features of the cotmtry, as it gives such a peculiar aspect to the mountains that they are known as the " black rocks/' He writes that it is " probably a non-described species of the prolific genus Scyton&ma, which in that situation during the rainy season generates and multiplies so rapidly that the upper portions of the Chroococcus] xxiv. chroo \< i b (West). 381 mountains ore covered with Li in a very short tim< after the hoi season has ael in, .-it the end of May, when the horizon above the Presidium is generally clear and bright, the black plantlets begin bo discolour with the intense heal gradually become dry and brittle until they peel off altogethei n\ and-by, after which the rocks lose their sombre black and reappear in their natural grej or grej brownisl [ova before the succeeding spring." Welwitsch named this planl Scytonema chorographicum, and gave a figure which is hardly charact We bave described i1 n&Scytonema Myochroua vox. chorographicum (Journ. Bot. 1897, p. 265) ; see ante, p. 371. Mixed with it is a quantity of Dichothrix gypsophila. \\>- states that " the wonderful growth of Scytonema in such i lense quantities is no! confined to the mountain ridge of the Presidium. ... In proof of this fact, 1 may refer to the damp sandy upper valley of the Cuanza Eliver, where a species of Scytonema is abundant, frequently ex- tending across the wide meadows, closely spread like a nel over the soil, iiitt'iiirnwii with (lit' other heihs ami sm.-i ll#-i- shrubfi Through its hygroscopic nature it eagerly absorbs the atmo- spheric moisture during the dewy nights, affording by this means eshing protection to the roots of many other and Larger plants during the glowing heat of the following day. The growth and thriving of the numerous small phanerogamous plants in these places is conditional on the co-presence of the prolific Scytonema." This second "Scytonema" alluded to by Welwitsch is Porphyrosiphon Notarisii, one of the Vaginariea ; see ante, p. 375. A parallel to this phenomenon is found on the sandy heaths <>!' the south and some parts of the north of England. A.1 the drier and hotter periods of the year, thickly matted sheets of Z ria torn in arc t<> be found extending over wide patches of almost bare sand, round such plants as Brosera, r,,,-;,-.-, etc. These interlacing masses have grea! absorptive capacity, gi lily taking up water ; it is also highly probable thai they protecl and render the growth of other plants more possible by regulating the moisture of the surface soil. It is interesting to note that Zygnema ericetorwm is found intermixed in small quantity with the Por ohyronphon Notarisii which covers such extensive areas in Angola. ' K\ Journ.
