Selaginella rubricaulis (No. 47) when he was working with his

herbarium in London. The specimens were found near Capopa,

woods at about 1500 to 2000 ft. In fr. Dec. 1880. No. 56. Baker
(Syn. Fil.), and Mettenius in Kuhn, Fil. Afr. p. 158, have referred
this species to D. elegans Sw. (D. denticulata Mett.). If the spurious
venules so characteristic of D. e/vgans are of any value for determining
species, this plant cannot be included in that species.

Dec. 1860. No. 56.

GoLUNGO ALTO.—On the banks of the river Delamboa, near Tange,
4 to 6 and even 8 ft. high ; in good fr. Sept. 1856. No.124b. In dense
primitive woods at Sobato de Quilombo, near the rivulets, and not
far from the Adansonia on which Rhipsalis was found. In fr.
Jan. 1855. No. 126.

Two young plants from this district are found in Welwitsch’s Herb. ;
the one, No. 124, was found in the primitive woods by the river
Delamboa, near Sange, July 1856; and the other, No. 125, appeared
in his garden at Golungo, a seedling the spores of which were brought
with plants from Sobato de Bumba. These both belong to this
species. ;

Punco ANnponGo.—On wet shady rocks in Barrancas de Catete
near the presidium. In fr. Dec. 1856. No. 77.

This cannot be distinguished from the South American species to
which Mettenius referred it. D.concinna Schrad. from South Africa
has the pinne decreasing downwards as well as upwards, while the
fronds of D. thecifera H.B.K., are sub-deltoid, with the pinnze largest
at the base. D. Schimperi Hk. is a synonym of D. concinna Schrad.
There are specimens of D. thecifera H.B.K. in Herb. Mus. Brit.,
from Madagascar collected by the Rev. Deans Cowan, and from
Equatorial Africa, east of Kiriandusi, 6100 ft., collected by Dr. J.
W. Gregory.

sides of the road between Cacarambolo and N-dele, frequent, but
rarely fruiting; Aug. 1855. No, 150b. In shady woods in the

mountains of Queta, by the side of torrents but not frequent ; Oct.
1854, Aug. 1855. No. 150c. : ae

Welwitsch distinguished this as a species, and gave it a name in his
Herb. It had been raised to this rank by R. Brown, from specimens
collected in the Congo region by Chr. Smith, and his herbarium name
A. pteropus has veen quoted in books. The striking character which
suggested Brown’s name is the broad wing on the short stalk of the
pinne, which also passes down the rachis.

3. A. Zollingeri Mett. teste J. E. Bommer.

Punco ANDONGO.—On schistose rocks near M-popo, not far from the
banks of the river Cuanza. In fr. April 1857. No. 149. Ina single

chiefly near the rivers of Sobati de Quilombo, 2500 to 2800 ft. high ; in
fr. July 1856. No.132a. Woods of Mata de Quisucula, Sobati de
Bango Aquitamba ; 29 April 1856. No. 1320.

Welwitsch observes that as the sori are not limited to the sinus, but
extend up the margins, even to the apex of the lobes, this species
exhibits a transition from Lonchitis to Pteris.

margins of the road from Sange to the source of the Capopa, 2000 ft. ;
Dec. 1856. No. 143.

Huituta.—On shaded rocks near the cataract of Ferrao de Sola near
Lopollo.

This is Pellea geranifolia Fée with the rounded distinct indusia of
Cheilanthes. Welwitsch says that a true indusium is present, which
appears not to be formed from the edge of the frond; this would
transfer it to the genus Pteris, where Kuhn places it, but it is, in my
judgment, a true Cheilanthes.

GoLunco ALTo —Rare at the margins of forests above the sources
of the Capopa, Sobati de Bumba, July 1855. No. 136. In the rainy
season this fern is intensely glaucous green, in the dry season the
pinne become contracted and involute, and look as if they were linear.

Hur_ia.—On dry and moist rocks between Humpata and Lopollo.
Jan., with fr. April 1860. Nos. 183, 1832, 183c.

A small plant from the same locality growing among P. hastata and
P. calomelanos (No. 183d) possesses characters common to the two
plants which led Dr. Welwitsch to question the value of the species.
This plant has the habit of P. hastata Link., but the segments are
scarcely subcrenate, the rachis is not winged, and the veins in the
segments are inconspicuous as in L. calomelanos Link. Welwitsch

suggests that it may be the plant named Pieris leucomelas Mett. in
Kuhn, Fil. Afr. p. 83.

this species which had already been used.

Stipes tufted, 3 to 6 in. long, clothed when young with
lanceolate acuminate caducous scales, erect, pale-coloured ; frond
4 to 15 in. long, 2 to 6 in. broad, with 5 to 10 pinne on each side,
which are 1 to 34 in. long, and 3 to 2 in. broad, stalked, apex
acuminate, cuneate at the base, the lower half more oblique, the
two sides of the pinna nearly equal, margin crenate or bluntly
serrate, terminal pinna somewhat larger than the others; veins
bifurcate except towards the apex of the pinna ; sori and indusium
linear, not reaching the margin.

Dr. Welwitsch considered this to be a trifid variety of the previous.
species. It may easily be distinguished by the triangular outline of
the lower pinnie, in which the pinnule of the lower side is not
abnormally large, so that the outline of the frond is deltoid acuminate
or somewhat five-angled. It is very polymorphic. Young specimens
in No. 107 are the form named by Hooker WN. Vogelii.

The plant from St. Thomas’s Island was named by Sir William

only a form and not a variety of A. punctatum. It has the main
veins distinct, and consequently belongs to the Gymmnopleris section
of the genus.

Welwitsch and Mettenius considered this fern should rank as a
distinct species. Welwitsch separates it because the fronds are impari-
pinnate to the apex ; the pinne are distinctly petiolate, and a bulbil
is found at the base of the last pinna. The pinne of the upper part
of the frond are subsessile ; they have in the barren frond long acumi-
nate apices, while the pinnz 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-
datum that it seems to deserve a place only as a variety of that species.

This fern is nearly allied to A. contaminans Wall. one of the species
included by Mr. Baker in A. virens Wall. In A. contaminans the two,
three, or four secondary veins run out from the vein free, while in
the African species the meshes of the secondary veins continue to or
almost to the margin, and only the veinlets reach the margin free.

most 5 to7 ft., bearing the fruit. The fronds erect, rigid. Almost
without doubt a halophyte.

Welwitsch describes the pendulous fertile fronds as simple, not
forked, obcuneate, very obtuse at the rounded dilated apex, and
gradually decreasing towards the long base. These characters are
given by Schweinfurth, and clearly shown in his woodcut. They
fully justify the specific rank of these plants, though Mr. Baker in his
New Ferns, p. 114 (1892), places the species under P. stemmaria Desv.

presidium, seldom bearing fr., but found with fr. at Barranco de

This species was previously known to occur In Brazil only ; and the
original plant was gathered by Swainson near Rio de Janeiro, according
to Hooker (Musc. Exot. t. 128). Hooker's Herbarium, however,
affords reason for the belief that the original locality was Bahia. The
African plant appears to differ from the Brazilian as redescribed by
C. Mueller (Synops. I. p. 761) in the lighter colour (yellowish brown),
more laciniate base and less rough (merely scab-ous) apex of the
calyptra.

Punco ANDONGO.—A densely cespitose, brilliantly green moss
occurring in spongy pulvinate tufts on wet gneiss rocks ; frequently
visited by Welwitsch, but always found in the sterile state ; at the
cataracts above Calunda in the most lofty parts of the presidium,
Oct. 1856 ; by rills in Mata de Pungo, Nov. 1856, and Feb., April
and middle of May 1857 ; near Cabondo, Jan., Feb., March 1857 ;

associated with Bryum argenteum (No. 70) on wet rocks by the rivulet
in Barranco de 8. Antonio within the presidium, always sterile, May
1857. No. 62. Also Alga No. 152.

The stems of this moss are usually branched at base, bearing long
(2 em.) simple branches which are straight or curved at apex, and
tomentose below ; leaves congested at apex ; the mature leaves exceed
1 mm. in length and are slightly papillate on the upper surface ; the
nerve is shortly excurrent at apex and decurrent at base, and the
margin is narrowly revolute along the whole of one side and in
the middle of the other side; the basal cells near the nerve are large
and lax and those near the margin are shorter, quadrate and sub-
obscure ; the upper cells are lax and the contracted primordial utricle
in them is persistent ; inflorescence not observed.

Some of the specimens under Welwitsch’s No. 61 may turn out to
belong to another species, with stems more branched, less tomentose.

380 geographical miles from the west coast, by David Livingstone ;
with fr. May 1855. No. 118.

In our specimens, which much resemble this widely distributed
species, the capsule and seta are blood-red in colour; the leaves are
less narrowly acuminate than in the type ; the nerve, arista and margin
are yellow ; the contracted primordial utricle of the laminal cells is
densely maculato-chlorophyllose.

Two other specimens, referred to this species by Duby, approach
more nearly to Brywimn alpinum in the shape of their leaves ; but in
other respects they differ from it, and they are both sterile. Their
numbers are as follows :—

Huvi.ia.—In elevated boggy wooded places by streams in Morro de
Monino, common enough but sterile ; Dec. 1859 and Feb. 1860. No. 25.
On roots of old trees and on rocks by streams in rather dense woods

time of gathering (May) very scanty or cropped by cattle, etc. : with
fr. in small quantity May 1860. No. 28.

The comal leaves are elliptical, with the upper part of the margin
denticulate and not convolute ; the margin near the base is narrowly
revolute ; the nerve and arista are yellow ; the densely chlorophyllose
contracted primordial utricle occupies the long diameter of the cells.
Welwitsch notes that the capsule is viridescent or at length here and
there brick-red.

HvILLa.—A cespitose moss of Mnioid habit, with proliferous stems;
rather rare on the base of old trunks in damp woods by the Monino
brook, but only in the more elevated rocky stations, and never seen
in fruit by Welwitsch ; April and May 1860. No. 4.

The leaves are 4 mm. long, with margins revolute from base almost
to apex; the primordial utricle of the cells is contracted and densely
chlorophyllose ; the marginal cells are long, thick-walled, yellow, but
do not form a thickened limb.

Welwitsch paid much attention to this species. He considered that
it differs from O. 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 O. Judianum.

Both of our tickets are plazed under the same number, and the
specimens are mixed. These latter belong to the section Orthostichella,
and in habit rather resemble P. viridis Jaeg. Gen. et Spec. IL., p. 162,
but the ramuline leaves are spathulate from a contracted base, obsoletely
binervate, more longly acuminate, with upper margins involute and
serrulate. The leaves are pentastichously arranged ; and those of the
primary branches are nearly twice as long as the ramuline, and bear an
elongated subulate flexuose acumen about 0°6 mm. in length.

Calyptothecivan | MossES (Gepp). 293

Sterile. Secondary stems 5 to 10 cm. long, densely or laxly
pinnate or divided into two or three pinnate branches, yellowish
green at apex, scarcely shining, dull and lutescent with age and
soon decaying; pinne 0°5 to 1:2 em. long, obtuse at apex,
occasionally longer and attenuate at apex; leaves 2-2 to 2-4 mm.
long, 0-9 mm. wide near base, complanate, rugulose when dry, from
a wider auriculato-cordate base ovate then ligulate (0-45 mm.
wide), acute, shortly acuminate, either symmetrical and slightly
hollowed, or concave on one side; margins flexuose especially
near base, entire or obsoletely serrulate below, serrulate near
apex; nerve slender reaching or surpassing the middle of the
leaf; cells pellucid linear vermicular, becoming elliptic and
rhomboid obscure in the auricles and lax quadrate, brown with
age, at the basal angles ; cell-walls firm yellow indistinctly porose.

This species is probably closely allied to Veckera acutifolia Brid.,
as described by Bescherelle in Ann. Sci. Nat. ser. 6, t. x. p. 273
(1880), and still more to Calyptotheciwm subacutifolium Broth. in
Engl. Bot. Jahrb. xxiv. ii. p. 254 (1897); but appears to differ
from the latter in the lighter colour of the plant and in the less
hollow more auriculate leaves, and from the former in the smaller
size of the plant and the dull surface and different shape of the
leaves. The firm yellow cell-walls distinguish our plants from
such allies as MNeckera Moritzii C. Muell. and Pterobrywm
duplicatum Mitt., in which the cell-walls of the leaves are thicker,
cartilaginous and distinctly porose.

This species is allied perhaps to If. (Huhookeria) Preussii
described by Brotherus in Engler’s Botan. Jahrb. xx. p. 201
(1894), and is distinct from it in having wider branches, longer
and more easily moistened leaves and probably larger areolation.
Tt is a larger plant than H. Breuteliana Hampe, and its leaves
are not half as wide as those of 7. Vallis-gratie Hampe.

Huitta.—A moss with leaves remarkably glaucons and rather
fleshy in the living state ; rather rarely occurring on the ground by
oldish tree-trunks, in company with Utriculariz and Xyrides, etc., in

the spongy swamps on Morro de Monino at an elevation of 5400 ft. ;

shaded sides of springs and rivulets in almost entirely rocky places at
a considerable elevation ; but only in the Barranco de Pedra de S.

3. H. contracta Gepp. sp. n.

Monoicous ; green, dilute at apex ; yellowish at base. Branches
adscending, simple or laxly and irregularly pinnate, 2°5 to 7-0 cm.
long, complanate, with the foliage 3-5 mm. wide; branchlets 0°6
to 1:2 cm. long, obtuse. Lateral leaves reflexo-patulous, con-
tracted, unaltered when wet, variously flexed, asymmetrical,
2:0 mm. long by 0°€ wide, oblongo-lanceolate, acuminate ; margins
elimbate, more or less infolded on one side and with a small
auricle at the base of the other (convex) side, strongly serrate
above the middle, with the subapical serrations geminate ; nerves
two, short, vanishing below the middle; cells elongated (5 by 1),
contracted, densely chlorophyllose, with pellucid walls. Median
leaves shorter. Perichetial bracts smaller, more narrowly
acuminate, less strongly serrate, with subapical serrations
geminate. Seta 17 mm. long, smooth, red; theca (unique,
damaged) inclined, oval?, with neck scaberulous, } as long;
operculum rostrate, $ as long.

This plant is readily distinguished from H. angolensis Welw. et
Duby by the less crowded, less imbricate, more flexuous, more
sharply acuminate leaves, the cells of which are contracted and
obscured by chlorophyll. In the apical leaves only do the cells,
when moistened, expand and become hexagonal and pellucid.

Var. impolitum Gepp. var. nov.

Ramuline leaves not shining, in the dry state less closely
appressed than in the type, plicate under pressure, more widely
acuminulate.

Puxco ANDoNGU.—A yellowish green, creeping, widely ceespitose
moss, found on rotting old trunks in Barrancos de Catete, and more
rarely on the bare ground in the same place ; with operculate fr. and
very fugacious calyptras, May 1857. No. 84.

Goitctnco ALTo;—On trunks and branches of Hdwurdia lurida in the
forests of Quilombo-Quiacatubia, at an elevation of 2400 ft. ; with old
fr. end of Feb. 1855. No. 164. Growing with Macromitrium lyco-
podioides on old trunks, especially on Edwardia, in the rocky woody
parts of Sobato de Quilombo-Quiacatubia ; July 1856. No. 144. Wel-
witsch says he also gathered the plant at Alto Queta.

2, E. bicolor Gepp sp. n.

Plant closely and widely interwoven. Stem creeping, rooting,
pinnately branched, with leaves homomallous. Branches numerous,
ascending, curved, brunnescent below, flavescent above, terete-
julaceous, scarcely polished, obtuse, 3 to5 mm. long, 0-4 mm. wide
when dry, 1:0 wide when wet. Ramuline leaves appressed when
dry, erecto-patent when wet, 0°85 mm. long by 0°375 mm. wide,
from a broad cordate base elliptic-ovate acuminate, slightly
hollowed, shortly binervate, with margins erect or slightly re-
curved, minutely serrulate above middle; alar cells quadrate
numerous, ascending to } length of margin, 0:01 to 0-015 mm.
diam., with primordial utricle contracted, dense; upper cells
vermiform-elongate (0°05 by 0-006 mm.), smooth, with walls
lutescent.

Huiria.—A densely and widely ceespitose moss, covering the older
tree-trunks on the northern and western sides ; on nearly lifeless bark
s = elevated woods of Monino near Lopollo ; without fr. Apr. 1860.

o. 8.

This sterile specimen appears to belong to the present genus. In
habit and in leaf-structure it is related to E. subjulaceum Paris, but
differs in the shape of the leaves which are oblong-ovate, half as wide,
much less excavate. The leaves approach in shape more nearly to
those of E. Schweinfurthi Paris (Index Bryolog. p. 437), but are much
less excavate and have much less visibly reflexed margins.

35. TRACHYPHYLLUM Gepp gen. nov.

A genus of the family Hntodontew, nearest to Erythrodontium
and differing in the papillate dorsal surface of the leaves and in
the inclined, lopsided theca, It is distinguished from Pterigyn-
andrum by the very numerous alar cells of its leaves.

_ Stem prostrate, more or less pinnate; branches ascending,
julaceous ; leaves appressed (apex patent) when dry, very patent

Trachyphyllum| mosses (Gepp). 299

when wet, cordate-ovate acuminate, rathcr concave, shortly bi-
costate ; margins erect; back papillate; alar cells multi-seriate,
small, quadrate to rhomboid-oblate, reaching to the base of the
nerves and to or beyond the middle of the margin, obscured
by the contracted, chlorophyllose, primordial utricle ; upper cells
linear-elliptic with apices projecting from the back of the leaf.
Perichetium longly exserted; seta elongate; theca inclined,
unequal ; operculum brevirostrate. Peristome (in 7’. gastrodes)
teeth with a median furrow outside, and with lamellate trabecule
inside; processes plicate and cilia solitary, subequal to them
(Duby). Calyptra unknown.

Huiiia.—On rocks and old tree-trunks in the elevated rocky parts
of Serra da Xella, where the Turchonanthus woods begin, bearing very
scanty fruit, most of the thecas having already fallen off; however,
specimens with a few entire capsules were found June 1860. No. 22.
Mixed with No. 32 (Braunia arbuscula) but apparently of rather rare
occurrence ; on Tarchonanthus in rocky woods at the summit of Serra
da Xella ; without fr. June 1860. No. 189.

This genus is designed for the reception of a few vagrant species
which, though mostly unknown in the fruiting state, have in common
a well-marked vegetative habit in the expansive movement of the
leaves upon the application of water, and in the areolation of the
leaves and their papillate dorsal surface. In the leaf-structure an
approach to Evrythrodontium is indicated, but the inclined, campto-
carpous fruit is not found in that genus.

The other species refered to the genus are :—

Sr. Tuomas’s Istanp.—A beautiful species, named after the dis-
tinguished Dr. Frid. Hopffer, Medical Officer of Health in the Cape de
Verde Islands. Welwitsch proceeds to describe this moss as czespitose,
with a Hypnoid habit, or rather with the habit of a Hookeria ; with
stems prostrate rooting, and leaves distichous bright green. Plant of
a bright and varying green colour ; leaves from a wide amplexicaul
base ovate-lanceolate, gradually acuminate, nerveless, densely areolate
with narrow elongate cells ; margin serrulate. Rather rare, growing
with Hepatics on old trunks in the dense primitive forests of Novo
Destino, at an elevation of about 2500 ft.; with fr. Dec. 1860. No. 125.

This species is closely related to R. megapelma C. Muell. in Dusén,
Musci Africani Camerun. exsicc. No. 221, which is described under
Hypnum (Rhynchostegium) megapelma by Brotherus in Engl. Bot.
Jahrb. xx. p. 212 (1894). But Welwitsch’s plant is distinct in its

lighter brighter colour, its less crowded leaves, more chlorophyllose
leaf-cells, and stouter untwisted seta.

Go.Lunco ALTo.—Growing in company with Rucopilum tomentosum,
Hepatics and Adiantum Capillus Veneris, and covering with wide
patches of intense green the rocks by the great cataract of the Cuango
stream, but very rarely producing fruit; sparingly with fruit and
opercula Aug. 1855; but when Welwitsch returned in the ensuing
December to collect this moss in good fruiting state, he found its
whole splendour destroyed by the superabundance of the water of the
fall, the plants being partly submerged. No. 178, Closely mingled with
Ectropothecium golungense on moist shaded rocks in primitive woods
above Undelle at the spot called “O Quibolo” ; without fr. J uly 1856.

Huitita.—A widely czxspitose, flavescent-green moss; fruit-stalks
fusco-coccineous erect ; capsules inclined ; calyptras elongate-cylin-
drical, smooth, yellow, dropping off long before maturity. Common,
but rather rarely fruiting, at the foot of trees on the bushy swampy
plain near Humpata and Empalanca, atan elevation of 5100 to 5300 ft.;
with fr. Feb. 1860. No. 34. On the ground among bushes by the
cataract of Ferrio da Sola in the elevated plain of Lopollo ; without
fr. Feb. 1860. No. 21, Intermixed with Jsopterygiwm at the foot of
trees between Lopollo and Lake Ivantdla; Feb.1860. No. 45 in part.

2. R. concolor Gepp, sp. n.

Dioicous. Plant slender, cespitose, in tufts 7 cm. wide,
flavescent-green, shining. Stem creeping, with scattered rootlets,
pinnately branched. Branches numerous, suberect, mostly simple,
8 mm. long, homomallophyllous, 1:25 mm. wide with the leaves.
Leaves sub-orthostichous, imbricate, erecto-patent, from a con-
tracted base ovate, suddenly longly and narrowly acuminate,
excavate, with margins more or less revolute, serrulate above
middle, subserrate towards apex, with two short nerves; cells
elongate narrowly sinuato-elliptic, very dilutely chlorophyllose,
with pellucid hyaline cell-walls ; lowest basal cells concolorous ;
alar cells 3 or 4, very lax, hyaline, very thin-walled; supra-
alar few, lax, hyaline. Perichetial bracts 8, erect; outer 0°6
to 0°8 mm. long, lanceolate acuminate ; innermost 2°5 mm. long,
elliptic lanceolate, suddenly very longly and narrowly attenuate,
remotely serrate towards apex, with cells larger and firmer. Seta
15 mm. long, very slender, pale reddish, smooth,. bent at apex.
Theca inclined or horizontal, longly ellipsoidal, with a short neck,
fuscous. Peristome as in 2. variegatum. Operculum convex,
shortly and bluntly rostrate.

302 MossEs (Gepp). | Raphidostegeum

Hovirra.—A widely cespitose moss, of a brilliant green colour, or
sometimes of a shining flavescent green. Common, but seldom bearing
fruit, on the ground or at the foot of old trees in forests between
Lopollo and the Monino river ; with fr. end of Dec. 1859. No. 36.

This species is very closely related to R. rwriegatwm 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.

3. R. physaophyllos.

Pungo ANDUNGO.—A deep green, densely caespitose moss ; on damp
ground and at the foot of old tree-trunks in forests between Mutollo
and Candumba, but very rarely bearing fruit ; with fr. beginning of
March 1857. 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. The branches are obtuse, not pungent, at apex.

With the above species should be compared the following :—

GoLUNGO ALTO.—On bark with Rhynchostegium lutco-nitens, Zengas
do Queta ; without fr. No. 217, in part.

To the present genus are to be referred the following numbers
in the British Museum :—

Pungo ANDoNGO.—A creeping moss with ascending branches.
Apparently rather rare on dead branches of Vellosicw, on the more
elevated rocks within the presidium ; with scanty fr. end of April
1857. No. 73.

GoLtvuncy ALro.—In company with No. 170 (Stereophyllum lingue-
folium) and with some Hepatics on the bark of trees growing in the
shady forests of Serra de Alto Queta ; with fr: July 1856, Amongst
Hepatics, Queta Central; with fr. July 1856. Alto Queta Central ;
with fr. July 1856 ; in company with No. 167 (Porotrichum elongatum)

on rather stout living trunks in dense primitive woods near Trombeta;

This species, which bears a misleading resemblance to the Hylutupis
section of the genus //ovkeria, is nearly allied to 7’. truncatulum Jaeg.
et Sauerb. gathered in Peru by Péppig ; also to Taxithelium perplani-
caule Broth. from the Cameroons (Dusén, No. 704), but in that plant
the leaves are not papillate.

Punco AxDonGo.—On old tree-trunks near the great cataract of
the Cuanza river at Condo and Mata de Quisonde ; specimens with
opercala and with young calyptras gathered in the same place ; with
fr, March 1857. No. 98.

The foliage of this species is compressed as in 7’. compressicaule
Broth. from the Cameroons (Dusén, No. 758), but the leaves of
Welwitsch’s plant are shorter, more obtuse, with the alar cells larger
and colourless, and the upper cells seriately papillate.

2. T. andongense Gepp, sp. n.

Widely cespitose, lutescent-green, dull; branches elongate,
creeping, straggling, here and there attached by rootlets,
pinnately branched; branchlets up to 2 cm. long, patulous,
flexuose, compressed, laxly foliose, obtuse ; ramuline leaves laxly
imbricate, patent, concave, from a constricted base oblong or
ovate-oblong, very shortly acuminate or obtuse and terminated
by short apiculus; margins erect, at apex minutely denticulate ;
nerves wanting ; cells elongate, very narrow, smooth or bearing
a single median dorsal papilla (more rarely two seriate papilla) ;
alar cells 3 to 5, vesicular, hyaline; supra-alar few, hyaline,
quadrate. Inflorescence, fruit, etc., wanting.

Punco AnponGco.—In the shaded woody parts of Barranco de Pedra
de San Antonio ; sterile, May 1857. No. 112.

This species differs from the preceding in being of a deeper green
colour and of a straggling and more irregular babit, but especially in
the scarcity of papilla on the leaf-cells. It is quite distinct from
T. compressicaule Broth. (Cameroons, Dusén, No. 758) in habit, and
from 7. rotundatului. Broth. (Cameroons, Dusén, No. 703) in habit,
leaf-shape and papillae.

very short or obsolete ; cells elongate, very narrow, with firm
flavid walls, basilar cells lax, alar two upon two subquadrate,
lax; perichetial bracts erect, lanceolate, longly acuminate,
serrulate; seta 15 mm. high; theca subhorizontal, ovoid, with a
short rugulose neck ; endostome processes subperforate, cilia one
or two interspersed ; operculum obliquely conic, shortly rostrate.

Hvriia.—Terrestrial or on the base of old trunks in the forests of
Leguminose, called “ Matas de Panda” j.c. Brachystegia and Berlinia,
between Lopollo and Lake Ivantala, collected during the flight ; with
fr. end of Feb. 1860. No. 45.

This species resembles J. Antunesii Broth. in Engl. Bot. Jahrb.
XXIV. ii. p. 264 (1897), gathered in Huilla, in the imbricated arrange-
ment of its leaves, but is a smaller and much more slender plant with
a short-necked theca.

2. I. Dubyi Gepp, sp. n.

Antoicous. Plant rather robust, widely and laxly cespitose,
flavescent-green, depressed. Stem 5 to 6 cm. long, creeping, laxly
pinnately branched, with homomallous leaves; branches 7 to
13 mm. long, usually simple, very compressed, with rather dense
foliage, diameter with the leaves 2°5 mm., obtuse. Rameal leaves
very complanate, widely divergent, rather hollow, obliquely ovato-
lanceolate, shortly acuminate, with margins a little recurved,
quite entire or at the apex very minutely serrulate or denticu-
late; nerves two very slender, 1 the length of the leaf; cells
elongate (10 by 0°75 y.), basilar lax; perichetial bracts erect,
lanceolate, longly acuminate, minutely serrulate above, lower
cells lax, basal cells brown ; seta 14 to 15 mm. high, yellowish-
red; theca horizontal, oval, subincurved, with mouth oblique,
neck short rugulose ; processes of endostome subperforate, cilia
solitary ; operculum convex, shortly rostrate.

Puneo ANDONGO.—A very pretty and not uncommon moss, yellow-
green, or bright-gold in drier situations, widely caspitose on stones and
moist earth by rivulets and springs in the woody parts of Barrancos
de Mata de Pungo ; with fr. beginning of May 1857. No. 97.

This species bears some resemblance to Hypnum leucophanes Hampe
(Plagiothecium C, Muell. ; Isopterygium Jaeg. et Sauerb.) in its foliage
but has wider leaf-cells.

Allied to the preceding species are the following numbers :—
Punco Anponco.—In company with Campylopus horridus (Welw.
No. 76), Barranco de Pedra Songue ; with fr. April 1857. No. 77.
Within the priesidium on shady ground near Caghuy, with unripe fr. ;
and on moist ground in rocky places near Caghuy, not far from

The type of this species was gathered by H. Soyaux in Pungo
Andongo on moist rocks by the river Engamzambe ; 30 March 1875.

Possibly the following sterile and imperfect specimens also
belong to this species :—

on the banks of rivulets in dense woods ; Mata de Quisucula ; Jan.
1856. No. 172.

strephomischos Jaeg. et Sauerb., Gen. et Spec. Muse. il. p. 539 (1879).

GoLttnco ALTO.—Flavous-green, rather shining, widely and densely
cespitose, but apparently very rarely bearing fruit, [the British
Museum specimens are well supplied with fruit]; on the withering
fronds of rather large ferns (Platycerium angolense Welw.) in the
forests of Quibanga; with fr. July 1856. No,179. In the same place ;
not however on Platycerium itself, but at the foot of the same tree: on
ground by the tree on which was growing Platycerium, the matrix of
No. 179, in the forests of Quibanga ; with fr. July 1856. No. 1790.

In size and general appearance this species approaches exceedingly
closely to Vesicularia bryocarpa C. Muell. in Dusén’s mosses from the
Cameroons (No. 311), but differs in having a pendulous (not inclined)
theca and in not fruiting copiously. To L. contractile Broth. from the
Cameroons (Preuss, No. 1026) it is also nearly allied, especially in the
texture of the leaves. The leaf-cells contract and become indistinct
when dry, and expand very slowly in water. The leaves of Welwitsch’s
plant are much more longly and gradually acuminate, and the stems
are not nearly so long as in E. contractile.

The following specimen, the fruit of which was already
destroyed when Welwitsch collected the plant, is allied to the
above species and also to #. glauculum, described by Brotherus
in Bol. Soc. Brot. viii. p. 186 (1890), and collected in the same
island by Quintas :-—

Istanp or Sr. THomas.—Ceespitose on moist rocks and on half-
rotten trunks in the vicinity, in the woods of Novo Destino, at an

A remarkable species agreeing with the subgenus Vesicularia in its
habit, in the complanate arrangement of its diversiform leaves, but
distinct in the Porotrichoid areolation of the leaves. The leaves are of
two sorts ; those of the upper side are distichous, patulous, imbricate
complanate, 1:0 mm. long by 0:45 mm. wide, from a narrowed base,
obliquely ovate (rotundate on one side, infolded on the other side) acute
shortly acuminate, faintly bicostate, with margins irregularly denticu-
late above middle and here and there revolute ; cells pachydermatous
upper oval-hexagonal (0°012 by 0-006 mm.), lower longly elliptic”
hexagonal (0-025 by 0-005 mm.), alar impressed and difficult to distin-
guish but apparently three or four fugacious inflated hyaline cells
with a few sub-obscure quadrate cells superposed Leaves of the
under side variable in size (0°6 to 1-0 mm. long by 0°25 to 0:3 mm. wide)
patent froma ieee or ner a lanceolate longly acuminate, with
margins more or less recurved, cells all elongatel iptic (0-0
0-005 mm.) sinuous with cell-walls 0-005 mm. hele the ee oe eo

1. L. golungense Gepp, sp. n.

Monoicous. Plants laxly cespitose, pale green, not glistening ;
stem creeping, sparingly and irregularly pinnately branched ;
branchlets 5 to 10 mm. long by 4 to 5 mm. wide (with leaves),
complanate, obtuse, with rather lax foliage ; lateral leaves patu-
lous, rather curved, lanceolate, median leaves elliptic, all rather
hollow piliform-acuminate, nerveless, quite entire; cells lax,
rhomboidal; perichetial bracts much smaller, the innermost
being truncate, erose, suddenly longly apiculate; seta 10 mm.
long, red, towards its apex curved and slightly scaberulous ; theca
inchned or horizontal, oval, occasionally substrumous, more or
less constricted below the mouth when dry.

Gotunco ALto.—Subglaucescent (when gathered), very laxly
cespitulose on rocks and trees alongside the Catombe rivulet in the
mountains of Alto Queta, but in small quantity ; with fr. middle of
June 1857. No.191. A moss of an intense and bright glaucous-green
colour, covering exposed muddy spots by rivulets in the primitive
forests of Quisucula, in company with Begonia; with fr. June 1856.

These plants appear to be so closely related as to belong to one and
the same species, of which No, 93 is the type. Variations in the size
and shape of the leaves are common to all. The youngest leaves
usually have their cells plainly unipapillate, while on the older leaves
the papillee are seldom conspicuous, No 92, the type Hypnum decolo-
rans Welw. et Duby, is characterised by its darker colour and slower
capacity for absorbing water, both of which properties may be due
to the influence of its place of growth, The species is at once
distinguished from S. omalosekos by having a seta more than twice
as long, and theca nearly twice as long.

GoLuNGo ALTo.—A bright-green obtuse-leaved moss occurring on
the sturdy trunks of trees, especially Meliacese (ntandrophragma),
growing in the shaded primitive forests of Serra de Alto Queta, but
sparingly ; also in Trombeta and Queta Central; with young and
mature fr. Dec. 1855 and Aug. 1857; also on the older trunks of
Entandrophragma angolense in the forests of Quibolo; with fr. May
1856. No. 170. With Eulejeunea Brewtelii on tree trunks in the
forests of Queta Central; July 1855. No. 220, in part.

This species is nearly allied to S. Basseanum CG. Muell, (Dusén Exsicc.
No. 7) and to 8S. leptotapes C. Muell. (Dusén Exsicc. No. 676), both
from the Cameroons, but is a smaller plant with the apices of its leaves
more obtuse and rounder and the cell-walls thicker. S. nitens Mitt.,
described in Trans. Linn. Soc. xxiii. p. 51 (1860-2), is characterised as
having its leaves subacute at apex, and appears to have narrower and
less elliptical leaves (/.c., tab. v. fig. 3).

4. §. auriculatum Gepp, sp. n.

Monoicous. A small, corticolous, depressed, glistening plant ;
stem adhering with brown rootlets, vaguely branched ; branches
prostrate, complanate, of 2 mm. diam. with their leaves, obtuse ;
lateral leaves patent, median appressed, all concave, from a
contracted base longly ovato-lanceolate acute, 1:65 mm. long by
0-6 mm. wide, with margin more or less infolded on one side and
serrulate towards apex, sometimes with four or five apical
denticulations ; nerve slender and vanishing in the middle of the
leaf ; cells of the basal angles of the leaf quadrate and numerous,
and forming on one side of the lateral leaves a flavescent sub-
inflated auricle with laxer cells, upper cells elongate and firm-
walled, apical longly elliptic, all smooth; perichetial bracts
smaller, acuminate, serrulate; seta 10 mm. long, red, slender,
curved at apex; theca sub-horizontal, oval, more than 1 mm.

the plicate membrane rising to half the length of the teeth and
bearing subperforated processes and solitary cilia, both papillate ;
operculum convex, shortly, thickly and obliquely rostrate.

Punco ANxDoNGO,--Caspitose on trunks of old trees in damp forests
near Luxillo ; with fr. middle of May 1857. No.107. A few small
specimens with all their capsules unfortunately lost, gathered on the
bark of old trees of “ Mucuco”’ (Gigalobiwm abyssinicum), upon the
more elevated rocks (3300 ft.) within the presidium, beginning of
May 1857. No. 81.

This species is closely allied to S. linguwfolium, but is readily dis-
tinguished by its acutely pointed leaves usually auriculate on one side
of the base.

The following numbers represent indeterminate specimens or
mixtures of scraps :—

HEPATICS.

By F. 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 Zulejeunia flava Spruce, Frullania squarrosa
Nees, Dumortiera hirsuta R. Bl. et N., Cyathodium cavernarum
Kunze, Aneura pinguis Dumort., and Anthoceros communis Steph. ;
others belong to the flora of tropical South America, like
Lopholejeunea Sagreana Spr., Cololejewnea crenatiflora Steph., and
Symphyogyna brasiliensis Nees. Quite a number have been found
also at the Cape: for instance, Lejewnea Breutelii, L. Pappeana,
Ricciella Rautanenii, and Plagiochasma muricata.

What remains is entirely of African origin; and the most
interesting specimen is Hxormotheca 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. Graf zu
Solms-Laubach in a splendid paper [Bot. Zeit. (1897) pp. 1-16,
tab. I.] has already expressed an opinion to this effect.

widely rotundate at apex and shortly bilobed, everywhere almost
plane, beneath the apex only exhibiting a short groove, on
the postical side a little incrassate; costa convex, longly and
gradually attenuated into the wings; margins thin. Frond in
transverse section six times wider than thick; antical surface
plane, postical widely lunate, with the angles longly acuminate,

collects exsicc., sched. No. 247 (nomen).

Monoicous. Plant rather small, green or pale-green, densely
stratified, corticolous. Stem up to 2 em. long, sparingly branched.
Leaves subopposite, distichously patulous, oblongo-conical, with
margins straight, at apex not half as wide as at base, at apex
lunately excised, bispinose, the spines being short and nearly of
equal size and narrowly triangulate. Leaf-cells 28 p, at base 28
by 37 »; trigones minute. Amphigastria three times as wide
as the stem, widely lunately excised, on each side bispinose and
broadly united with the leaves. Perianths terminal, ie. not
borne on innovations, oblongo-triquetrous, at apex deeply multi-
laciniate, broadly winged, the wings being irregularly and grossly
spinose. Innermost floral leaves little larger than the cauline,
at apex truncato-bidentulous, with margins paucidenticulate.
Innermost floral amphigastrium small, broadly connate with its
proper leaves, subquadrate, quadrilaciniate to half its length, the
innermost laciniz being the stouter. Andreecia terminal on the
branches, fusiform ; bracts exciso-bifidulous to one-third of their

2. P. decurrens Steph. sp. n.

Dioicous. Plant rather small, slender, densely czespitose,
olivaceous. Stem up to 4 cm. long, very much and almost fascicu-
lately branched ; branches subsimple and pinnately divided at
the top into short floriferous branchlets. Leaves not spreading
much from the stem (at an angle of 30°), obliquely oblong, on the
postical side shortly inserted, longly incumbent on the stem, on
the antical side very longly decurrent, at apex truncate bi-
tridentate, upper margin sparingly dentate, the teeth being

leaves from a narrow base obliquely ovate, at apex subtruncate,
margins everywhere grossly crenato-spinose, quite entire at the
base only.

The original specimen was gathered by Dusén in the Cameroons.
The species is most distinct; it is easily recognised by its very
decurrent leaves, and can be compared with no other species
hitherto known.

22. NOTOTHYLAS Sulliv. Musci Alleghan. p. 69 (1846).

1. N. angolensis Steph. sp. n. :

Dioicous. Plant large, green, depresso-cespitose. Frond
10 mm. long, from a narrow base widely obconic, at apex thick,
lobulate, very crispate. Costa very longly radicellose, abruptly
produced, yet shallow; wings of the frond longly attenuate.
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 yu, flavescent,
smooth ; elaters a little smaller than the spores, with the spiral
fibre reduced to three lamelle which run round the wall
meridionally. Anthers unknown. Involucre large, 3- or 4-winged
superficially with minute lamelle, especially rough on the wings.

Pungo Anpon«o.— 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 WN. decurrva Mitten, and differs
from that species in the size and thickness of the frond. The size and
‘sculpture of the spores of NV. decurva are not stated by the author.

2. N. flabellata Steph. sp. n.

Anthoceros flabellatus Welw. ms.

Monoicous. Plant very large, densely stratified, green at apex,
elsewhere flavo-rubescent. Frond up to 3 em. long, repeatedly
furcate, with the forks very thin (3 to 4 cells thick), with the
margin remotely pinnate; pinne 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,),
under the microscope brown, minutely rough. laters very short
(28 by 34), more than twice as large as the spores, sub-hyaline,
bispirous, with the spirals laxly coiled. Anthers solitary? in a
large cavity.

Pungo ANDoNGO.—Plant orbicular, 1 to 4 in. wide, bright green,
with fruits bright orange shining as if varnished ; on wet rocks by the
rivulet of Casalalé within the presidium, at an elevation of about
-3000 ft. ; with perfect fr. May 1857. No. 181.

Notothylas| nePATICS (Stephani). 321

A very curious plant, the largest of the genus, extremely thin and
very much branched, quite unlike any other species of Notothylas ; the
involucre of the capsule is decumbent, being inserted on one side, but
for a very short distance only ; very curious also is the innovation of
the frond from the base of the fruit, quite a new feature in this class
of plants, of which the terminal cells are used up for the formation of
the pistillidia. The elaters are formed inside a mother-cell (just like
the spores, 4 together) and are real tetrahedrons ; but they lose their
form and become inflated by the action of the spiral bands, as soon as
they are set free.

Notothylas has always numerous pistilla within one flower; the
occurrence of 2 capsules springing from the same point is therefore not.
surprising, though it has never before been observed.

CHARACE.

A certain number of the alge collected by Dr. Welwitsch are
not sutliciently well preserved to be named specifically, and are
therefore not given here. Among these are species of Cyanophycee,
Cladophora, Sargassum, Dictyota, Corallinee, Gracilaria, Poly-
siphonia, and Nitophyllum.

FRESHWATER ALG.

DETERMINED BY

W. WEST, F.L.S., anD G. S. WEST, B.A., A.R.C.S.

The alge which form the subject of this paper were collected
some forty years ago by Dr. Welwitsch during his eight years’
residence in Angola. They are chiefly from the latter region, but
a few are from Benguella and Sierra Leone. The specimens are
all dried ones, and for the most part are mounted on paper. Por-
tions of all had to be soaked out for investigation, the results of
which have been very gratifying, as by this means, after a detailed
examination, many of the smaller species have been observed.
These latter, however, had not been collected as such, but, inde-
pendently entangled among other conspicuous species, had been
collected with them. The Desmids had practically all been
unconsciously obtained in this way, few, if any, collections having
been made from places in which one would expect to find Desmids
in abundance; and yet about 130 fine species (including fifty
undescribed ones) have been found as intruders amongst other
alge. From these mere samples one is led to wonder as to the
richness of the Desmid-tlora of Tropical Africa.

Very little is known concerning the Freshwater Alge of Africa,
only a few small scattered papers having as yet been published ;
and this extensive collection—one in which almost all the groups
are represented—very considerably enlarges our knowledge of the
geographical distribution of these plants.

At the time these alge were collected the great majority of
the species were as yet undescribed. They form part of the
Welwitsch collection deposited in the British Museum, and the
numbers after the species refer to the numbers on the sheets of
this collection. A few of the species can hardly be considered as
freshwater ones, but as they were in the collection we have
included them.

It is interesting to note that the earliest collection of algze made
in Africa has been found to be more extensive and representative
than any hitherto described. The species are localised under the
various districts of the region, exactly as indicated by Welwitsch
on his herbarium labels. (Ex Journ. Bot. 1897, pp. 1, 2.)

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. The filaments are
not much thicker at the nodes than between them.

This is a rather noteworthy species, being so much branched that

pencils ; the plant when dry is almost black, and looks like some of
the marine Floridec.

This very beautiful species is characterized hy 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.

delicate B. atrum Harv., except as to its branching, This species and

B. angolense adhere but slightly.

Most of the plants had formed or were forming hypnospores, which
when fully mature were globose or subglobose, with very thick
lamellose walls; a few of these had evidently been formed from
but part of the contents of a cell, and were externally nodulose.
The cells had a very lamellose membrane, which character is most
conspicuous during the formation of the bypnospores, the filaments

The green contents entirely fill the cells when living, but when
dry they contract into a double-cone-shaped or dumb-bell-shaped
mass in each cell. The brarches rarely bear branchlets, except
very short ones consisting of one or two cells. The species which
most nearly approaches it is 7. tenuis (Zell.) De Toni, from which
it differs in its green colour, in its rather smaller size, in the equal
thickness of its primary filaments and branches, and in its obovate
zoogonidangia.

This is a remarkable plant more particularly on account of its
special conjugating cells ; these are short, and cut off either singly
or in pairs at intervals along the filaments. In the former case the
conjugation is scalariform ; these special cells in two contiguous

Temnogametum] 1X. TEMNOGAMETACE® (West). 337

filaments put out short rounded conjugating tubes which unite, the
cells themselves becoming bent towards each other, and very soon
the two cells coalesce and form the zygospore. In this way a zygospore
is produced which at first sight very much resembles the central cell
of the five cells constituting the spore of a J/ougeotia of the section
Staurospermee. In those filaments in which the pairs of cells are cut.
off the conjugation is lateral, the two cells forming a zygospore much
resembling the aplanospore of a Gonatonema. In fact, these zygo-
spores are oblique, and the convexities and concavities alternate along
the filament precisely as in the case of a sporiferous filament of the
latter genus.

Both scalariform and lateral conjugation occur in the same filaments.
In all the specimens observed (which had been dry for a loug period)
the contents of the thick-walled spores appeared to have contracted
into two approximate rounded masses ; whether the latter had ever
been perfectly united or had yet to unite within the wall of the
spore is a matter that could not be definitely decided from the
material.

On account of the peculiar conjugation, this plant has been placed as
the type of a new order—Temnogametucew—of Conjugate.

Huitia.—In paludibus exsiccandis ; April 1860. No. 176.

This characteristic species belongs to the section Staurospermum ; in
maturely conjugated specimens this can only be inferred from the
genuflexed conjugating cells, but the young zygospores are subrectan-
gular or subquadrate. The four processes present on the zygospores
are developed very early, considerably before the zygospores are ripe,
and are rarely of equal length ; they are of the same diameter as the
vegetative cells, and fit into them very closely.

This is a most characteristic species; spores with processes of
this nature are possessed only by two other alge in the order
Zygnemacee, viz. Mougeotia uberosperma and M. irregularis, The
consecutive spores, which are very large, are alternately oblique, the
cells containing them being very slightly bent alternately to the
right and left.

The fact that only a portion of the contents of the conjugating cells
participates in the formation of the zygospore indicates a relationship
to the fam. Jesocarpee, although the arrangement of the chromato-
phores in the ordinary vegetative cells much resembles the arrangement
in the genus Zyguema (fam. Zygnemew). The character of the
zygospores is, however, quite unique, and the plant has therefore
been placed in a new family, Pyxisporea.

This most interesting species has very remarkable spores both with
regard to their colour and markings. The original specimens from the
Sandwich Islands described by Dr. Nordstedt had only aplanospores
(hence the specific name) ; the African specimens have only zygospores.
The relationship between the aplanospores and zygospores in this
species is in all respects comparable to that between those of Z.
pachydermum West ; in the latter species the aplanospores are also
smaller, globose, and possess a thinner membrane.

This genus seems to be near Tetmemorus and Kuastrum. It re-
sembles the former in its elongate form, in being but slightly con-
stricted in the middle, and in possessing a circular (or very nearly
circular) vertical view ; it differs from it, however, in the absence of
the deep linear notch at the apex, in the presence of a spine at each
apical angle, and in the general conformation of the upper half of the
semicells, which are somewhat wedge-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 to be much less firm than that of a
Tetmemorus. The punctulations on it are in some specimens dense
and in others distant from each other, and occasionally they are so
well developed at the apical angles as to give them a faintly rough
appearance, In one example the spine at one of the apical angles
was duplicated, the two spines being placed close together, and of
different lengths.

It also approaches the genus J'riploceros, but the delicate character
of the membrane, which is also destitute of warts, and the somewhat
different apex distinguish it.

The front view of this species is considerably different from that
of E. intermedium Cleve, a depressed form of which it somewhat
resembles at first sight, and the vertical and lateral views readily
distinguish it from all Euastra of this class.

rectangular polar lobe as seen in front view ; from the vertical view
the polar lobe is oblong-elliptical, and not sinuate-quadrate.

This variety appears to connect M. arcuata with M. pinnatifida ; its
lobes are thicker and more horizontal than in typical examples of the
former, and the basal ones much resemble those of the latter. The
lobes, however, are not so thick and have not the same form as those
of J. pinnatifida, the apex of the polar lobe is retuse in the middle,
and the lobes all possess that small terminal sharp spine characteristic
of all specimens of AZ. arcuata.

This beautiful and characteristic species has a very robust appear-
ance on account of the shortness and thickners of the lobes; the
subuncinate form of the lateral lobes is also peculiar.

The African form has a higher polar lobe than the Polish one, and
the infra-apical incision isa little more open. Eichler & Gutwinski’s
measurement igiven in the text, “long. cell.=86 p,” is evidently a
mistake, as their figure measures but 39 p.

In this variety there are two more spines on each semi-ce]l than in
typical specimens of X, cristatwm, and the semi-cells are of a somewhat
different form ; it may perhaps be another species.

It differs from X. trélobum Nordst. [in Vidensk. Medd. Naturh. Foren.
1869, no. 14-15, 230-1, t. iii. f. 35 (1870)], in being more distinctly
trilobed with a rectangular sinus between the terminal and lateral
lobes, in the lobes being more rectangular, in the presence of a spine
in the middle of the outer margin of each lateral lobe, in the absence
of crenulation at the inferior angles of the latter, in the rectangular
polar lobe having but one spine at each angle (as seen in vertical
view), and in the narrower vertical view with a more prominent
central protuberance.

This species is closely allied to X. calcarato-aculeatum (Holocanthum
calcarato-aculeutum Hieronymus in Engler, Pflanzenwelt Ost-Afrika,
Theil C, 20 (1895)), described from the opposite side of the African
continent at about the same latitude.

The apex is subrectangular with a broad elevation at each angle,
and another elevation in the centre, the latter not being as high as
those at the angles. The four pairs of scrobiculations are somewhat
variable (cf. loc. cit. t. 367, £. 4-6) ; sometimes there are three in
place of either or both of the two central pairs.

This differs from C. subwndulatum Wille in its shorter cells, its
truncate apices, its crenate lateral margins, its entire absence of granules,
and in its different vertical and lateral views. From C. subundulatum
var. Beunlandii West it differs in its crenate lateral margin, its more
truncate apices, in the absence of granules, and in its different vertical
view.

This Stavrastrum belongs to the same section as S. quadricornutum
Roy & Biss. and S. gemelliparum Nordst., but is very distinct from
either. Each of the three angles of the semi-cells is more or less
quadrate with a short bifurcate process at the two upper corners,
with an emarginate wart at each of the lower corners, and a short
stout spine between the two emarginate warts.

seen in vertical view) easily distinguishes this species from S. Hystrix
Ralfs. At each angle there are two large spines in a vertical plane,
and about six much smaller ones round them; the latter are some-
times regularly disposed in a circle round the two larger ones.

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.

The character and arrangement of these warts, however, its less
incurved processes, the different form of its semicells, together with
the constantly fusiform vertical view, readily distinguish it.

We see no reason for Turner’s genus Staurophanwm, as no clear

would include and those referable to Tetraédron. Indeed Tetraédron
pusillum is very closely connected through its var. angolense with

After enumerating the characters of his “First Subgenus” of

term Ouracoccus might be applied to the species of this subgenus.”
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 Uvococcus is to stand, it must be as Urococcus Kitz.

The habit, together with the gradual attenuation of the filaments,
brings this nearest to C. adscendens (Nig.) Born. et Flah. (i.c., 365) ;
but its smaller size, its shorter filaments, and its very short cells easily
distinguish it. The younger plants, which have only attained a
length of about 100» and a thickness of 5°5-7'5 p., have their cells
only 2-3 times shorter than the diameter. It also comes near to
C. endophytica Lemmermann in Forschungsberichte Biolog. Station
zu Plén, iv. 184 (1896), but has a different sheath and very short
filaments ; the heterocysts are also very distinct.

XVI. SIROSIPHONIACE®.
1. HAPALOSIPHON Nig. (1849).

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.

nosis paludosis juxta rivulum Lopollo ; April 1860. No. 180. Etiam

This species occurs in minute tufts, and the great resemblance to
each other of the primary filaments and branches, together with their
thick yellowish sheaths, characterise it.

This has a very distinct facies from H. luteolus, being of a bright
golden brown colour, with more tortuose filaments, the sheaths of
which have a very different appearance; the cells also are much
more variable (and usually longer), the branches are more numerous
and of a thickness different from that of the primary filaments, and
often arise in pairs.

This species may be compared with //. hibernicus W. et G. S. West
(in Journ, R. M. 8. 1896, 163), from which it differs in the longer
cells of the primary filaments ; in having much fewer branches, which
are also shorter and not flexuose ; moreover, the cells of the branches,
as well as the heterocysts, never attain the length of those of
HY, hibernicus. Compare also with JZ, intricatus West.

2. STIGONEMA Ag. (1824).

The cells of this genus are protoplasmically continuous through-
out the whole plant, a fine strand of protoplasm, passing from
cell to cell along the middle of the filament, effecting this con-
tinuity. This is best seen in plants that have been dried and

connecting threads are not visible in living plants, but in becoming
dry the protoplasm shrinks away from the minute canal along
which it passes through the septa, and on soaking again does not
reattain its natural position.

The cell-walls are very thin indeed, not any more appreciable than
the cell-walls in the ordinary vegetative cells of a Nostoc. The majority
of the heterocysts are lateral, globose, and either sessile or stalked
(usually supported on one or two cells) ; sometimes they are intercalary,
and then they are always elliptic-oblong.

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, aud 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 Hapalosiphon. Taking into consideration all these
points, there are still unmistakable characters which place the plant in
the genus Scytonem«a.

2, TOLYPOTHRIX Kiitz. (1843).

After examining the three following species, we cannot agree
with Bornet and Flahault in separating the genera Hassalia and
Tolypothrix. 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 Hassallia, but
the sheaths (especially that of 7’. crassa) are very firm, persistent,
and flexile, agreeing with those of Yolypothrix. Under which
genus ought these species to be placed? The terrestrial habit.
points to Huassallia, the flexile and non-fragile filaments to.
Tolypothrix. 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.

The diverse forms of the cells and their irregular disposition in the
short tapering filaments give a character to this genus not possessed by
any other of the genera of either the Vaginariee or the Lyngbyec, and
necessitated the plant being placed as the type of a new order (Campto-
trichee) of Hormogonecee Homocystew.

This Alga occasionally branches ; these branches are few and of the
same thickness as the primary filament, around which they are closely
coiled. The sheath of the branch becomes solid at the base, and is
gradually merged into that of the primary filament, its trichome not
being in any way connected with that of the latter. The branching
really consists of a close application of the base of one filament to the
sheath of another, the fusion being for such a short distance that the
two trichomes are never present within the same sheath. It is of
the same type as the branching present in Schizothriz, but the division
into branches is deeper, causing the branches and primary filaments to
be of equal thickness. The above remarks prove that Porphyrosiphon
is very closely related to Schzzothrix, and emphasizes its position in the
Vaginariee. This affinity was inferred by Gomont (in Ann. Sci. Nat.
7° série, Bot. xv. 332) from a consideration of an entirely different
character, viz. the structure of the sheath. Gomont’s statement on the
same page that Porphyrosiphon has no branches is, however, erroneous.

The peculiar sheaths of this genus readily distinguish it from the
other genera of the Vaginarie, its nearest ally being Dasyglea Thw.,
from which it differs in the very firm multitubular sheath with an
open apex, and in the much thicker trichomes with very much shorter
cells. There is a very distinct line of demarcation between the inner
and outer constituents of the sheath, the outermost one being rendered
conspicuous only by the extraneous material adhering to it. The

trichomes are also usually without any interruption for a considerable
length.

This genus must be placed in the Lyngbyew 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 lamelle 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 now considerably broader.

The specimens of this species are very fine; it is a totally distinct
plant from Phorméidium angustissimum, though it is of the same thick-
ness. It possesses no sheath, and the trichomes are much firmer and
not so tortuose as those of the latter ; its cells also are shorter and
more indistinct.

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 subaérial alga is the cause of one of the main
features of the country, 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
Scytonema, which in that situation during the rainy season
genorates and multiplies so rapidly that the upper portions of the

Chroococeus | XXIV. CHROOCOCCACER (West). 381

mountains are covered with it in a very short time. . . . Soon
after the hot season has set in, at the end of May, when the
horizon above the Presidium is generally clear and bright, the
black plantlets begin to discolour with the intense heat. They
gradually become dry and brittle until they peel off altogether
by-and-by, after which the rocks lose their sombre black aspect,
and reappear in their natural grey or grey-brownish colour before
the succeeding spring.” Welwitsch named this plant Sceytonema
chorographicum, and gave a figure which is hardly characteristic.
We have described it as Scytonema Jfyochrous var. chorographicum
(Journ. Bot. 1897, p. 265) ; see ante, p. 371. Mixed with it is a
quantity of Dichothria gypsophila. He states that ‘the wonderful
growth of Sceytonema in such immense quantities is not confined
to the mountain ridge of the Presidium... . In proof of this
fact, I may refer to the damp sandy upper valley of the Cuanza
River, where a species of Scyéonema is abundant, frequently ex-
tending across the wide meadows, closely spread like a net over
the soil, intergrown with the other herbs and smaller shrubs.
Through its hygroscopic nature it eagerly absorbs the atmo-
spheric moisture during the dewy nights, affording by this means
a refreshing 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 Seytonema.” This second ‘“ Scytonema” alluded to by
Welwitsch is Porphyrosiphon Notarisii, one of the Vaginariece ;
see ante, p. 375.

A parallel to this phenomenon is found on the sandy heaths of
the south and some parts of the north of England. At the drier
and hotter periods of the year, thickly-matted sheets of Zygnema
ericetorum are to be found extending over wide patches of almost
bare sand, round such plants as Drosera, Carices, etc. These
interlacing masses have great absorptive capacity, greedily taking
up water ; it is also highly probable that they protect and render
the growth of other plants more possible by regulating the moisture
of the surface soil. It is interesting to note that Zygnema
ericetorum is found intermixed in small quantity with the Por-
phyrosiphon Notarisii which covers such extensive areas in Angola.

It may possibly be identical with Desmogoniwm guianense
Ehrenb. [in Schomb. Reisen in Brit. Guian. ITT. p. 539 (1848)],
but it has not the distinctive character upon which that genus
was founded.

I find no Diatoma in the material; and, as this species is the
most characteristic form present, I take it to be what is meant.
There are two forms :—

J. biconstricta, with a central inflation.

J. constricta, without a central inflation.

pany with Conferva ; remarkable for their metallic lustre in the dry

BENGUELLA.—A green Alga, very gregarious, forming yellowish-
green scum-like strata over several miles of the ocean about a mile
from the coast. Welwitsch records that on the 22nd and 23rd of June
1860, the sea in the Bay of Benguella was for several miles parallel to
the coast covered with strata of this Alga ; and he hazards the sugges-
tion that it might perhaps have been carried down with the flood out
of the river Catumbella. No. 184.

insignibus Reinkella et Ingaderia, a Darbishire detectis, apo-
thecia, que auctor mihi communicavit, et que parasite non esse

in statu juvenili evolutio thalli indagatur, quo modo solo certum
judicium de natura morphologica membrorum plante habert
