XC. LENTIBULARIACE A.
The members of this family produce but little effect on the physiognomy of vegetation in Angola; they, however, especially Genlisea africana, adorn with their innumerable mostly purple flowers the humid pastures of the Huilla highlands. Most of the aquatic and even the amphibious species bear yellow flowers, while the strictly terrestrial species are red, violet, purple, or white. In the coast districts only two species are found, and these belong to Utricularia. The terrestrial species begin to appear about 3000 ft. above the sea-level in soils that are kept moist even in the dry winter season by the presence of Alge ; they become more frequent and abundant both in species and individuals as the land rises in altitude, and they occur in the largest number of forms and species from 4500 to 5500 ft. The presence of the terrestrial species of Utricularia usually indicates a rich productive soil; and even where they grow on a sandy soil, as occasionally happens in Huilla and about Pungo Andongo, their appearance is mostly accompanied with some impregnation of the land with fertilizing materials. Heavy rains are apt completely to wash away the aquatic species, and many of the species suddenly disappear after a few hot and dry days.

The following No., represented in the British Museum set by a poor specimen, should be compared with this species, but the reference is very doubtful :—
Punco ANpDoNGoO.—A herb scarcely an inch high, growing in a cespitose manner, apparently perennial ; leaves erect-patent, somewhat fleshy, almost rosulate ; peduncles longer than the leaves ; fruit fallen. In rocky sandy-schistose places on the right bank of the river Cuanza ; without fl. end of Jan. 1857. No. 6748.

Hvui_ia.—A herb, apparently perennial ; radical leaf solitary, very large, very broadly cordate-ovate or cordate-oblong, obtuse at the apex,
790 XOI. GESNERACEA. [ Streptocarpus
bright green, coarsely wrinkled and velvety-pubescent above, whitish- shaggy scrobiculate and with thick pinnate nerves spreading beneath, at length fleshy-thickened near the base, lying close to the ground ; stem very short, fleshy, thickened, dichotomously or trichotomously divided a little above the crown of the root into purple scape-like some- what thick rigid several-flowered occasionally foliate branches ; flowers handsome, somewhat nodding, as large as those of a foxglove, violet- blue, some cauline, others solitary near the central stem from the crown of the root ; calyx deeply 5-cleft, scarcely 5-phyllous, short ; its lobes iin. long ; corolla tubular-funnelshaped, sub-bilabiate, the segments of the limb obtuse ; stamens 4, included, the posterior ones sterile ; the filaments narrowly clavate, those of the interior stamens incurved ; anthers sub-reniform, cohering ; ovary 1-celled, in form like the spike of a Myosurus ; placentas many-ovuled ; style firm, cylindrical ; stigma capitate-peltate, the apex thinly papillose, not bilabiate nor with reniform lobes ; capsule elongate-cylindrical, 1} to 2 in. long; the valves 2, spirally twisted together ; seeds very numerous and small.

No. 1660 and Coit, Carp. 36 (not found) and 821.
This species differs from S. Cooperi C. B. CL, /.c., by the presence of pubescence on the exterior of the corolla ; it may be identical with a plant collected by Buchanan in 1891,n.882,in Nyasaland. The solitary radical leaf is regarded as a persistent cotyledon ; see Crocker in Journ. Linn. Soc. v. p. 65, t. 4 (1860) and Dickie, /.c., ix. p. 126 (1865).
XCII. BIGNONIACEZ.
The species of Bignoniaceze found by Welwitsch in Angola and Benguella are in great disproportion to the total number, which amounts to between 500 and 600; this contrast is the more striking, because tropical countries in other parts of the earth form the principal seat of this Order.

Some fragments of the fruit of M. stenocurpa are intermixed with the fruit of this species in CoLu. Carp. 815 ; the description attached appears to belong exclusively to this species.
‘‘ Moluanda ” is the native name of a tree, belonging to Spathodea or an allied genus ; it has sulphur-coloured flowers and capsules a yard long ; the wood is strong and is generally used by the Golungo Alto negroes for the helves of pruning-hooks ; perhaps it belongs to this species.

than in other tropical countries; but as they consist mostly of herbs they do not greatly affect the physiognomy of the vegetation.
The tribe Pedalieze has only one representative in the collection, and of that one only a single specimen was found ; but it is very probable that Uncaria procumbens Burch., the grapple plant, occurs in the southern part of Mossamedes on the sandy Cunene plains.
The tribe Sesamez is most frequent about Benguella and in the Mossamedes district. Two species of Sesamum, namely, S. angolense and S. rigidum, have both opposite and alternate leaves on one and the same specimen. ‘The cultivation of S. orientale, which is carried on with profitable results in India, Egypt, Mozambique, etc., was started in Angola during the time when Pedro Alexandripho do Conha was governor-general, and again at a later period before Welwitsch’s time, though always with but small success; but the experiments appear not to have been made in the parts of the province best adapted for the purpose. The colonists complained that the exceedingly irregular ripening of the seeds so reduced the crop that the cultivation of this oil-plant had resulted in a loss; during the latter part of his travels, however, Welwitsch saw in the interior, chiefly on the high plateau east of Pungo Andongo, the plant cultivated by the negroes, though only in small quantities and for their own use, and he was firmly convinced that trials made by experienced colonists and in properly chosen districts in the highlands would lead to favourable results. The negroes of Pungo Andongo cultivate it, not for the extraction of oil, but for making cakes, which they bake with the crushed seeds, and which they look upon as a delicacy. In Cazengo the cultivation had been attempted and given up, as it was found that birds devoured the seeds of the Sesamum before they ripened, and that Arachis hypogea afforded a far more certain and profitable yield for the production of oil.
Several species possess roots containing a red dyeing material, which even in the herbarium stains paper, and they might’ perhaps be used for dyeing purposes; this material is most strongly developed in Sesamum triphyllum, a species which is widely distributed from the banks of the Maiombo behind Mossamedes up to the high plateau of Huilla. A mucilaginous infusion is obtained from species found about Lopollo and Huilla. S. pentaphyllum with its large violet-purple flowers, and still more so the S. angolense of Pungo Andongo, are very ornamental plants, and probably might, at least in the warmer European countries, be grown in the open air.

This family, which is abundantly represented in the Cape flora, was previously to Welwitsch’s discoveries unknown in West Tropical Africa ; the three species which were found in Huilla are among the most delightful of its plants, and embellish those high- lands with indescribable charms. The negresses, who are in general but little susceptible to the beauties of nature, are in the habit of weaving in their head-dresses the flowering branches of the two following species of Selago, or stick them behind their ears, as they carry goods to the market at Lopollo.

Welwitsch in Apontam., l.c., states that this is a very rare plant and was found by him only in one spot ; but in a ms. note he reported it as plentiful in another locality. It is perhaps the Stachytarpheta mentioned by Welwitsch in Ann. Cons. Ultramar. Lisb. No. 24 (May 1856), p. 250, n. 130, as an ornamental undershrub, 3 to 4 ft. high, with large white handsome flowers, and as growing in damp fields in the Loanda country, where it is rather rare and flowers from November to February.

The following two Nos. possibly belong to Premna, but I cannot identify them with any described species; they are apparently conspecific :—
GOLUNGO ALTO.—Shrubby ; branches spreading, ascending, glabrate or obsoletely puberulous, cinereous ; branchlets angular, beset with short close pallid stellate hairs ; leaves ternate or opposite, obovate, obtuse and apiculate at the apex, wedgeshaped at the base, thinly coriaceous, dark green and nearly glabrate above, paler and beset with short stellate pale hairs beneath, 2 to 3 in. long by ? to 1} in. broad, entire or subrepand on the very narrowly revolute margin, exstipulate, lateral veins about 6 on each side, slender ; petioles } to 3? in. long, hairy at least above ; inflorescence terminal and subterminal, branched, tomentose with pale stellate hairs, bracteate ; bracteoles narrow.

GoLunGco AttTo.—In the primitive forest a small tree of 6 to 8 ft., but in secondary thickets a shrub of 14 to 3 ft. sometimes somewhat erect sometimes almost decumbent ; leaves sometimes simple some- times trifoliolate ; infructescence axillary, cymose ; common peduncle 13 in. long, puberulous ; fruit glabrescent, } in. in diameter ; fruiting calyx hemispherical, sub-entire. In wooded sunny places and in rather dry open thickets in Sobata de Mussengue, at Menha-Lula; fr. May 1855. No. 5713. In fl. No. 5728.
Var. parvifolia.
Leaves trifoliolate or simple; the middle or only leaflet 13 to 2+ in. long by 1 to 1 in. broad ; the lateral ones smaller.
GoLunco ALTO.—A shrub of 6 to 8 ft., perhaps in the primitive forest a tree ; flowers violet-blue ; fruit like a grape in shape, almost as large as that of V. Cienkowskii (Welw. herb. nn. 5633, 5645). In the drier secondary thickets of Sobato de Mussengue; fl. Jan. 1856. No. 5636.
V. simplicifolia Oliv., .c., p. 133. t. 180, non C.B. Cl., is probably the same species, since our specimens include both simple and trifoliolate leaves and both longer and shorter peduncles.

Vitex | XCVI. VERBENACEE. 835
The following perhaps belongs here :— PuNGo ANDONGO.—A patently branched, bushy tree, 10 ft. high, with trifoliolate leaves and violet-coloured flowers; fruit obovoid,
1j in. long, with perfected seeds. At Candamba by the river Cuanza ; fr. March 1857. Cou. Carp. 847.

4. V. Welwitschii Giirke, /.c., p. 166.
GoLtunco ALTo.—An elegant, densely leafy tree, 12 to 25 ft, high or in the primitive forest probably taller ; leaves evergreen ; flower violet in colour ; drupes (not quite ripe) almost globose, in shape and size like those of a Queen Claude plum, juicy, at first greenish yellow, afterwards dusky purple. In secondary woods close to the declivities of the river Cuango, at the foot of the Queta mountains ; fl. June 1855 and March 1856; young fr. Aug. 1855. No. 5644.
This is perhaps the plant referred to by Welwitsch, Apontam. p. 585, n. 15, as a scarcely described species of Vitex or allied genus, occurring in the Golungo Alto primitive forests, and being a beautiful tree with widely spread crown, palmately 5- to 7-foliolate leaves, violet-coloured flowers, and large edible fruit prettily purple in the living state and greedily searched for by the negroes and wild birds.
5. V. cuspidata Hiern, sp.n.
A tall tree, in old age leafy only at the top; timber excellent ; branches spreading, minutely squamulose, smooth ; branchlets opposite, softly tomentellous, patent, tawny-shaggy at the tips; leaves opposite, spreading, digitately 3- to 5-foliolate; common petioles 2 to 4 in. long, slender, more or less tomentellous ; central leaflet obovate, acutely cuspidate at the apex, wedgeshaped at the shortly petiolulate base, thinly coriaceous, deep green rather glossy and more or less furnished with scattered minute tubercles or scales above, subferruginous and softly tomentellous especially along the midrib and spreading lateral veins beneath, entire, 24 to 43 in. long by 1| to 13 in. broad ; the lateral leaflets smaller ; infructescence axillary, lax, divaricately branched, equalling or exceeding the leaves; common peduncle 3 to 4} in. long, rigid, rather slender, tomentellous or obsoletely so; bracteoles narrow, deciduous, hairy; unripe fruit ovoid, obtuse, subglabrate, + in. long, $ in. broad, } in. thick; fruiting calyx subhemispherical, shortly puberulous or obsoletely so, + in. long, the lobes unequal, shallow.

very elegant ; branches spreading, the lower ones brachiate-ascending. In the primitive forests of mount Cungulungulo, rather rare, not opening its flowers for a whole year ; fl.-bud Feb. 1855. No. 5632.
The Fungus n. 42 at Camilungo in June 1855 grew on the decayed trunklets of a Vitex, perhaps this species.
The following two Nos. should be compared with this species ; the second one should also be compared with V. rivularis Giirke ms. in Pl. Zenker. n. 1333 from the Cameroons :—
GoLUNGO ALTo.—A young tree, 5 ft. high, resembling a horse- chestnut in habit. In the Queta forests, sparingly ; without fl. or fr. Oct. 1855. No. 5654. A tall tree, almost like a horse-chestnut in habit, differing from the last No. by its leaflets being acutely toothed at the apex and without ferruginous pubescence.

GoLuNnGco ALTO.—An extensive tree ; head very broad, depressed- hemispherical ; flowers violet in colour; fl. Jan. 1855 and May 1856. No. 5645. A vast tree, 30 to 50 ft. high; timber whitish, good ; head widely spreading ; branches patent, somewhat tortuous ; leaves hard ‘coriaceous, very rigid, glossy, subglaucous beneath ; flowers lilac like those of rosemary ; fruit like a grape in shape, as large as a moderate- ‘sized pigeon’s egg. In deep valleys among the Queta mountains, close to streams ; fl. Dec. 1855 ; fr. March 1856. No. 5633. A densely leafy tree, 12 ft. high, with somewhat erect branches and violet- coloured flowers. At Arimo de Mariano; fr. beginning of July 1856. Conti. Carp. 844. In forests near Sange, plentiful; fr. July 1857. Cort. Carp. 845. A handsome, evergreen tree; leaves 5-foliolate ; flowers pale violet in colour; fruit drupaceous blackish purple, with a large seed. In the primitive forests of Undelle; fr. Aug. 1857. Coun. Carp. 846.
Lichens nn. 291, 313, grew on the leaves, also Unona lucidula Oliv. (Welw. herb. no. 758) and Angraecum Galeandre Reichenb. f. (Welw. herb. no. 658) grew on this tree. The Bunda name is ‘‘ Muxillo-xillo”’ or ‘‘ Muxillo-xyllo;”’ see Welw. Apontam. p. 550 under no. 95, and Ficalho, Pl. Uteis, p. 241 (1884). The branches of the large trees are pendulous, and the flesh which envelopes the stone in the fruit is very oily. No. 5746, also from Golungo Alto, in fl.-bud and young fr., with leaflets narrowly elliptical or obovate wedgeshaped at base and ranging up to 83 in. long by 33 in. broad, and with petioles ranging up to 6 in. long, perhaps belongs here.
It was probably this tree, growing in the district of PUNGO ANDONGO, the heads of which were covered with the parasite Cassytha jiliformis L. (Welw. herb. no. 6428). It may also be the ‘“‘ Mucolocolo,” a very lofty tree with 5-foliolate leaves, racemose nodding flowers, and fruits as large as oranges containing oily seeds; plentiful in Golungo Alto, chiefly at the foot of meadows.

Vitex| XCVI. VERBENACES. 837
a shrublet of 2 ft. freely flowering and fruiting ; flowers violet-bluish. On rather dry bushy slopes and in reed-beds among the Queta mountains ; fl. May 1855. Nos. 5634, 5635. Roadway leading to Cubata de Tindandolo ; fl. April and May 1855. A form with the leaflets softly and shortly pilose beneath. No. 5695.
Var. ? pumila.
Punco ANnponGo.—Pedras de Guinga; in fl. and young fr. No. 5668. A small subglabrous shrub, 13 to 3 ft, high; stems numerous, simple, erect ; leaves 3- to 5-foliolate, coriaceous; flowers becoming violet in colour. In wooded thickets near Pedra de Guinga, rather rare; fl. March 1857. No. 5747.
The type specimen of the above species in the National Herbarium is too imperfect to warrant certainty of identification with our specimens ; the Pungo Andongo plants belong perhaps to a distinct species from those of Golungo Alto.
9. V. huillensis Hiern, sp. n.
Closely branched; branchlets ascending, obtusely angular, somewhat tawny or ashy, more or less tomentellous with pallid short soft hairs ; leaves mostly ternate, digitately 3- to 5-foliolate ; common petiole 1 to 2 in. long, pilose-tomentellous ; central leaflet obovate, often narrowly so, shortly acuminate pointed or rounded at the apex, wedgeshaped or obtuse at the base, thinly and firmly coriaceous, yellowish green and somewhat scabrid above with very short deciduous hairs arising from minutely tubercular persistent bases, pallid and softly and shortly pilosulous beneath, entire, 2 to 3} in. long by 1+ to 12 in. broad, shortly petiolulate ; lateral veins about 10 on each side of the midrib, slender, midrib prominent beneath ; lateral leaflets smaller ; inflorescence axillary, softly pilose-tomentose with pallid hairs, densely eymose, shorter and narrower than the leaves; common peduncle ? to 1+ in. long ; bracts very narrow, subulate, + in. long or shorter, deciduous ; ultimate pedicels very short ; flowers numerous, + to } in. long ; calyx hairy outside, glabrous inside, obliquely campanulate in flower, somewhat enlarged and hemispherical in young fruit, shortly 5-lobed; the lobes subdeltoid, pointed, somewhat unequal ; corolla-tube 4 to 4 in. long, above hairy outside, nearly glabrous below both inside and out, oblique at the top; the limb unequally 5-partite ; the lowest lobe rounded, ;4, in. long, suberect or spreading, hairy outside near the base, glabrous above and inside ; the other lobes smaller; the throat glabrous or nearly so; stamens 4, subdidynamous; filaments pilosulous, inserted about the middle of the corolla-tube ; anthers short, just exserted ; style + in. long, equalling the longer stamens, slender, glabrous or microscopically glandular, bifid at the top ; ovary small, 4-celled, as glabrous as the style.

XCVII. LABIATA.
Plants of this order are scarce in the coast regions of Angola, and are not plentiful in the mountainous forest districts, but in the highland-plateau regions they gradually increase both in genera and species, and become so abundant in individuals that they exercise a decided influence on the physiognomy of the pastures and banks of streams. Some genera are especially conspicuous in consequence of their large white or rosy bracts at the base of the white or violet-coloured flowers; several species have filipendulous rhizomes, and some are very pleasantly aromatic; the two species of 7%nnea furnish from their dried leaves antiscorbutic powders; and the genus Alvesia, when seen without its flowers, much resembles rosemary.

This is apparently the species of Ocimum, cultivated by the colonists in Golungo Alto, and also wild, which is called “ mangericio,” a Portuguese name which the negroes pronounce 7’gilicd. See Ficalho, Pl. Uteis, p. 241 (1884).
It is perhaps the Ocymwm species mentioned by Welwitsch in Ann. Cons. Ultramar. Lisb. No. 24 (May 1856), p. 250. n. 118, as an under- shrub remarkable for its very agreeable aroma and growing at Boa Vista, Cacuaco, 10 Aug. 1854.
This species is perhaps not distinct from O. basilicum L. ; according to Miller it grew naturally in India.
The following note, which was found in Herb. Welw. with No. 6554 (Philoxerus vermiculatus Sm,) but cannot belong to it, is called Ocimum, and possibly relates to No. 5568 as applied to this species or to No. 5567 :—

Plectranthus Welwitschii Vatke, mentioned by Briquet, /.c., under 44. obtusifolius Briq., included !. Engleri. 4. obtusifolius is stated to have been collected by Welwitsch, no. 473, at Malandsche (Malange) ; this is an error ; probably Mechow was the collector intended to be mentioned. I have not seen the type of . obtusifolius, but from Briquet’s description I suspect that Vatke was right in considering it as conspecific with 2. Engleri. Briquet, l.c., p. 190, describes also from Angola 2. floribundus, the type of which I have not seen ; but he states that it is very near to 2. obtusifolius, and that the two should, perhaps, be considered as forming varieties of an aggregate species for which he suggests the former name. The three species, namely, these

Such is the correct spelling -of the collector’s name, although in the Botanical Magazine, t. 6783, Mr. Baker stated that the bulb of Crinum leuwcophyllum, the plant which he there described, had been brought from Damara-land ‘‘ by a Danish sea captain of the name of Thuré Gustave Hin”; in the Flora of Tropical Africa, however, vil. p, 397 (1898), for the same species the name is given as Thure Gustaf Een.

In Golungo Alto this plant is very abundant; there and also in Pungo Andongo it is called ‘‘ Catete Bulla” ; the tender shoots and the leaves, dried and reduced to a powder, and administered either in bulk or in the form of a saturated infusion, were at times recommended to Welwitsch by the negro doctors as furnishing one of the most efficacious remedies for scorbutic diseases especially for those of the mouth ; he, however, had no opportunity of convincing himself of any salutary effects in such cases.

In Pungo Andongo it is abundant along streams: see note under Polygonum lanigerum R. Br. Welwitsch considered that this plant must have been originally introduced into Angola (and probably into all the other districts of Africa where it occurs) by the missionaries, because its fruit, as also that of Abrus, Canna, Coix, etc., is used for the so-called chaplets or crowns of roses.

Welwitsch was informed by Senhor Pompeio Pampilhio that this species occurs wild near Pungo Andongo. ‘The name “ napagaios ” is also used by the Portuguese colonists for /mpatiens Balsamina L. ; see ante p. 108. It was also found in Ambaca, near N-gombe, in plots neglected after cultivation, where it was not plentiful, in Oct. 1856. According to a ms. note of Welwitsch, this is one of the species which are both wild and cultivated by the natives and which furnish the edible vegetables called by the negroes “ Jimboa.” see Welw. Apontam. p. 547 sub n. 74 (1859), and Ficalho, Pl. Uteis, p. 242 (1884).

CII. CHENOPODIACE®.
This Order is not found to be numerous in Angola ; just as the Cruciferee are represented or replaced in tropical regions by the Capparideze, so are the Chenopodiacee by the Amaranthacee. Chenopodium graveolens, however, occurs in the interior on the plateau between Pungo Andongo and Condo and on the sandy forest slopes towards the Cuanza river, and sometimes in such masses that they exercise a wonderful influence on the appearance of those sandy steppes and are visible from a considerable distance on account of the blood-red colouring of their stems and leaves as well as their flowers. Not less plentifully does Arthrocnemum macrostachyum occur at the tidal mouths of some rivers between Ambriz and Rio Ongo; its colour is typically herbaceous-green, but when the salt water begins to dry and evaporate it sometimes turns violet or peach-red, and covering as it does the surrounding lowlands it then affords a striking and lovely prospect from the neighbouring high ground, along which the road through the Mossul country runs; it stains everything violet.
Basella alba 1., an herbaceous climber with fleshy leaves, is cultivated, though rarely, in some gardens, in Loanda and Golungo Alto, under the name of ‘“ Batavia.” Not less frequent is the cultivation of spinach (Spinacia oleracea L.). See Welw. Apontam. p. 947. n. 73.

The plants of this order have a remarkably peculiar habit resembling in this respect some Alge and Jungermanniz ; they are poorly represented in Angola, Welwitsch having collected only two out of the 170 species or thereabouts in all; these two species, moreover, were found each in a single station, namely in the cool and clear streams confined within rocks among the mountains of Pungo Andongo, though they were searched for in vain in similar situations up to 16° 8. Lat. and 5600 feet of altitude. One of the species strikingly resembles a Hypnea (Floridee), and it grows with a shield-like knotty base attached in an exactly similar fashion to stones at the bottom of the streams. The second species, which at first sight might be mistaken for a Jungermannia, occurs also at the bottom of streams, but it grows in dense extensive tufts after the manner of various Jungermannie. Each of the species seems rarely to bear fruit and then only when the streams in which they grow decrease so much in depth by evaporation in the hot season that the plants have their upper branches exposed to the atmosphere. The texture also of these species resembles that of some Alge; they have the same elastic stiffness when taken fresh out of the water, the same rapid crumbling, the same knot-like appearance of the stem (though on closer examination really different), and the same kind of cartilaginous disk at the point of attachment.

Pungo ANDoNGO.—An aquatic herb, 3 to 10 in. long, branched in a dichotomous or fasciculate manner like Fontinalis antipyretica, attached after the fashion of the Floridez, with a shield-like cartilaginous sordid-rosy or purplish callus, to the submerged rocks in clear streams, when removed from the water rapidly becoming very limp; stems several from the same root, cespitosely clustered, the young ones erect, subcompressed, greenish purple, the older and fruiting ones floating, flatly compressed, reddish purple, subcartilaginous and as the branches and branchlets (which are at length subcylindrical) semipellucid and flexible, in youth more densely and in adult age more loosely leafy ; leaves alternate, apparently distichous but really trifarious, those of two rows distichously patent, those of the third row shorter, erect, adpressed to the stem, almost imitating the amphigastria of Junger- manniz, all very brightly deep-green, oblong-lanceolate, obtuse, l-nerved, quite entire, narrowed and sub-decurrent at the base ; flowers axillary, solitary, at first subsessile and involucrate with bracteoles, soon with firm rather thick straight and long peduncles ; bracteoles at length oblong, rather broad, membranous, 2 or 3, usually 2, at the base of the peduncle at length free, spreading, persistent in fruit ; perianth-segments 3, thinly chartaceous, green, at first sub- connate beyond the middle, at length as the ovary enlarges free to the base, equal, ovate-oblong, concave, adhering to the mature ovary, persis- tent, then spreading, but little or scarcely exceeding the capsule ; stamen 1, hypogynous ; filament compressed-filiform, at the beginning of the flowering included, soon rather far exserted ; anther 1, terminal, red, attached at the emarginate base, ovoid-oblong, 2-celled, dehiscing longitudinally ; ovary ovoid, incompletely (?) 3-celled, the cells with several ovules ; stigmas 3, purple, filiform, erect during the flowering, at length diverging ; capsule brick-red-brown, oblong-ovoid, crowned at the top with the indurated styles, longitudinally sulcate-costatx, 3-valved ; the valves tricostate, boat-shaped, when dehisced laying bare a placentiferous column which bears the erect seeds in its depressions ; seeds very numerous, elongate-ellipsoidal, compressedly biconvex ; testa thin, pellucid, somewhat viscid ; the inner lining bright brown, very delicately and roundly foveolate.

A small parasite, growing in masses, after the fashion of the tubercle-shaped Spheeriz, on the thinner branchlets of trees on all sides, but chiefly on the side exposed to the light, springing from their bark sometimes in definite rows and in other cases irregularly. Slender threads or very delicate membranes pervade the liber and take the place of the root like a mycelium. The parasites first appear as small hemispherical nodules, which are afterwards broken by the protrusion of a rather hard globular or somewhat conical light brown body appearing under the microscope to be covered with small tender more or less circular scales which give the globular body an areolate surface and make it quite analogous to the uterus of some Fungi, as for instance Clathrus, and almost of a woody consistency ; it soon bursts either irregularly or in a circumsciss manner, the upper arched part falling off like a hood, and the lower part remaining firm on the bark like an elevated bowl-shaped ring, which permanently encircles the buds as they sprout and the fruit when subsequently formed. The whole of the process, from the first manifestation of the little nodules up to the inflorescence and fructification, appears to be completed in a very few days: thus Welwitsch found on the 10th May 1860 male flowers which were then nearly all in bud with only a few having their perianth expanded, and two days later he found the same flowers nearly all quite withered and past. On a close examination of these fungus-like plants Welwitsch was involun- tarily reminded of the flowers of certain Asclepiadex especially of some Stapelie ; and the foul smell of the latter is said to occur in some species of Rafflesiew. The flowers are diccious, involu- crate ; involucre globose, crustaceous, pale brown, branny-areolate, smooth inside, enclosing one or rarely two (in one instance three) flowers, circumsciss or bursting irregularly, the patelliform base

persistent ; flower subsessile at the bottom and centre of the involucre, bright rosy-bloodred throughout, $ to 4 in. high. bud- shaped, bracteate; bracts several, 8 to 10, scale-like, broadly ovate, concave, obtuse, bright bloodred, arranged in an ascending spiral, covering the perianth of the flowers, whether of the male flowers at the time of the flowering or of the female flowers both during the flowering and during the swelling of the ovary. Perianth of the male flowers 4- to 7- or even 8-phyllous ; the segments obtuse, spongy-callous at the base inside, imbricate in the bud, erect-spreading during the flowering, incurved at the apex; corona of the throat 4- to 8-angled, the angles prominent and alternating with the segments of the perianth; staminal column subconical-cylindrical, truncate at the apex, sheathing the column of the free style; anthers contiguous, sessile, below the apex of the staminal column; pollen copious, whitish ; style- column cylindrical ; stigma hemispherical-peltate, exserted, closing the cavity of the staminal column; ovary obsolete; all parts of the flower at first rosy purple, soon bloodred and marcescent, afterwards reddish yellow, always more or less fleshy, and the flower when rubbed abounding in a red carmine juice which imparts to paper a tolerably fast colour. In the female flowers the buds (and also the expanded flowers) are a little longer and narrower than in the male flowers, ovoid-conical and not globose as in the male; perianth almost completely covered by the scale- like somewhat fleshy bracts, adhering to the ovary, 6-phyllous ; the segments scarcely ever well expanded, resembling the bracts in colour, consistency and shape, quite glabrous, spongy-callous at the base inside; corona of the throat not flat but prismatic, analo- gous to the septiform membranes in Cytinus, 6-angled, the angles prominent and alternating with the segments of the perianth ; ovary half inferior, globose-ellipsoidal, unilocular ; placentation parietal ; ovules numerous ; style from the centre of the corona erect, broadly conical, viscid-fleshy ; stigma hemispherical-capitate, rarely 2- very rarely 3-umbonate, tubercular, very delicately wrinkled; seeds very many, bright flesh-coloured, wrapped in a viscid material, scarcely arranged in regular order, soft, slightly crustaceous.
Hv1ia.—Parasitical on branchlets of the Panda tree, Berlinia pani- culata Benth. (Welw. herb. no. 577), the male plant seen only on this tree ; in the elevated (5500 ft.) forests of Morro de Monino, sparingly ; male fl. 10 May 1860. No. 5290. On branchlets of the Panda tree, Brachystegia spiceformis Benth. (Welw. herb. no. 583); in the same neighbourhood as the male plants but rarer ; female fl. 12 May 1860. No. 529.
The plant seems to be very rare, for during the seven months during which Welwitsch was almost always and even daily traversing the forests chiefly composed of Leguminous trees, he found it only on a few Leguminous trees, all of which belonged to those called Panda trees, once on a glabrous kind and a second time male plants on a tomentose variety of Panda.
A small bread-coloured Curculio attacks and quickly destroys the

flowers and fruits of the Pélostyles ; and even two species of Curculio were met with in one and the same flower.
Welwitsch considered that the flowers of this plant are not theo- retically without peduncles, any more than those of Lemna or Pistia, but that the stalks are extremely reduced, just as the axis of the inflorescence in Composite; this view is confirmed by the spiral arrangement of the bracts.

MossAMEDES.—A fleshy-coriaceous plant, like a fungus in shape, dusky-brickred throughout ; smell stercoraceous ; rhizome or under- ground stem thick, dull and purple-dusty outside, pale brickred inside, 5- to 7-gonal, horizontal or obliquely ascending, sparingly and remotely dichotomous, fleshy inside, beset along all the angles outside with blunt papilliform warts, perennial, parasitical on the roots of Zygophyllum orbiculatum Welw. (herb. no. 1637 and Coll. Carp. 27) and on a succulent Kuphorbia (which it ultimately kills; cf. Welw. herb. no. 643), growing all the year round, producing in succession flowers from the angles of the rhizome, of which the first appear to be rudimentary and to constitute the rows of tubercles on the angles ; perianth tubular, 3 to 8 in. high, an inch in diameter, obconic-cylindrical, bluntly rounded at the base, attenuate to the sessile base and there connate with the ovary, gradually widening upwards, deeply and transversely wrinkled, orange-red tending to brickred inside, dusky-cinnamon in colour outside, 3- or very rarely 4-cleft at the apex ; the segments of the limb valvate in estivation, ragged inside, connivent or even connate to the extreme tip; the sinuses rounded, not lobulate at the base ; some or all of the segments very broadly furrowed within, bearing in the furrow a gland which covers all the upper part of the cavity of the furrow and is at first white and soon becomes dusky ; the substance whitish-subferruginous, soon deliquescing and at the same time turning dusky and stinking after the manner of certain fungi; stamens isomerous with the perianth segments, 3 or 4, and opposite to them ; filaments inserted on a ring at the middle of the tube and concrete with it; anthers cohering at the base, free at the apex, pyramidal-conical, blunt, many-celled, whitish-straw in colour ; the cells parallel, unequal in length, transverse, variously curved or bent; ovary inferior, adnate to the tube below the anthers, 1-celled; placentas very numerous, densely ovuled, perpendicularly dependent in the cavity of the tube, bright white ; ovules bright white ; stigma subsessile, thick, broadly pulvinate, somewhat 3- or 4-lobed, sordidly purple-dusky, pale brick- red inside ; the lobes shortly convex, delicately but clearly marked with transverse furrows. On maritime sandy hills near Mossamedes and as far as Cabo Negro, plentiful ; fl. and fr. April, 23 June, and July 1859. No. 530.
The plant in all parts and especially in the rhizome abounds in a
Hydnora| CVI. CYTINACER. 911
dusky cinnamon colouring matter which also contains tannin, and for this reason is frequently employed with complete success by the Mossamedes fishermen for staining their nets and preserving them for a long time from decay. Thunberg spoke of the plant as a fungus; and in his time it was known in South Africa by the name of “ Jackhal’s Kost.” See Thunberg’s Travels, Engl. ed., ii. p. 133 (1795).

This is the “‘ Moscadeira Brava” (wild nutmeg tree) of Angola; both the fruits and the nuts of this African species are smaller than those of the Indian nutmeg, and cannot rival the latter in aroma ; but they abound in oil, which in Welwitsch’s opinion could be utilized for various domestic purposes, and probably also in pharmacy ; the trees are very productive, each one bears many alquiers (23 pints) of fruits (see Welw.

916 CXI, PROTEACE,
CXI. PROTEACE.
Two suffruticose species of Leucadendron L. occur in Angola proper ; they grow in great abundance, forming broad clumps on the rather dry hills and at the outskirts of forests in the neighbourhood of the great cataract of the river Cuanza from Bumba to near Quisonde ; a third species, which is a small tree, was met with in the forests of Pedras de Guinga, but without flower or fruit ; all the three species were found within the limits of an hour and a half’s walk between Bumba and Condo, and there remained not the least trace of Proteacez elsewhere throughout the whole plateau of Angola proper.
The Proteacez of Huilla are all with one exception very local and restricted to very limited districts ; the species of Fawrea were seen in a very few stations and were represented by only few specimens, with the exception of /. saligna Harv. ; during Wel- witsch’s frequent excursions, extending over eight months, across the wide highland plateau of Huilla, which is dotted with numerous mountain forests, he found only ten or twelve trees of one species of Leucadendron; and a similar statement applies to a species of Fawrea with leaves glaucous beneath.
With reference to the peculiar geographical distribution of this Family in South Africa, Burchell remarked (Travels, i. p. 208) that on entering the Karro region, about 32° 40’ 8. Lat., ‘‘ four of the strongest and most characteristic features of Cape botany, the Erice, the Diosmz, and the Proteaceous and Restiaceous tribes entirely disappeared,” and that again seven degrees farther north Protea argentea L., the ‘‘ wagenboom ” of the Cape colonists, or at least a nearly related species, reappeared, although in the whole of the intervening country, where he botanized for two years, ‘‘this genus and several others which characterize the botany of the Cape were nowhere to be seen” (Burchell, L.c., 11. p. 475); Dr. Kirk reported only one Proteacea from the whole of Zambesia.
In his letter addressed to Alph. de Candolle (in Archiv. Se. Phys. Genéve, July 1861, p. 11), Welwitsch showed that his discoveries led to the conclusion that on the west side of Africa the Cape flora extends towards the north, but that on the east side the tropical flora extends southwards towards the Cape; these observations thus confirmed the somewhat similar view of Drége in Flora, 1843, Besond. Beig. ii. pp. 19, 20.
In Welwitsch’s opinion Proteaceze are intimately related to Loranthacez ; compare the perianth of Fawrea discolor Welw. ; Loranthacez, indeed, seem to be merely parasitical Proteacez. The scales or bracts subtending each flower in certain species of Faurea are really cupuliform, and are fixed on the rachis of the spike like an external calyx, possibly analogous to a corresponding condition in Tricalysia (Rubiace). The hairs or beards of Proteaceee are very changeable in colour; they are sometimes.
Leucadendron | CXI, PROTEACES. 917
however constant, and indeed in one species, namely fawrea saligna Harv., the beard on the pistil sometimes remains white, while in other cases it turns tawny or rufous. The marginate condition of the leaves or otherwise is frequently a bad character and difficult to distinguish. The limb of the perianth in some species is circumscissile and deciduous.
See Welw. Apontam. p. 548. n. 80, and p, 579. nota 9 (1859).
In Huilla the Proteacez are held in high esteem for firewood, and Welwitsch from his own experience confirmed their reputation.

CXIU. LORANTHACEA.
The number of species and also that of individuals of the same species increase progressively from the sea coast towards the highlands of the interior, and culminate in the mountainous forests of the districts of Pungo Andongo and Huilla at an elevation between 4000 and 6000 feet.
Nearly all the species are erect or more or less spreading shrubs from | to 25 ft. high, but one species forms a pendulous shrub with slender branches 4 to 6 ft. long. Most of the species of Loranthus as well as the single species of Viscwm grow on the lower or higher or even on the top branches of evergreen trees, and less frequently on deciduous trees; only a few brilliantly flowering species occur in the torrid and treeless coast region, at the base of low shrubs of Malvaceze and Petalidiwm very much in the same manner as Cytinus Hypocistus L. grows on Cistus on the sandy plains of Portugal; sometimes in the hot littoral region a beautiful Loranthus is met with growing, not at the base, but on the middle branches, or even on the main stem of low slender twiggy shrubs, and in such cases the combination of the bright green and broad-leaved parasite and its gay crimson flowers with the thinner and differently shaped foliage of the foster plant, forms one of the most striking features of parasitic vegetation along the sea coast of Benguella and Mossamedes ; for instance, a small bush of Gossypium or allied genus, only 2 to 3 ft. high, bore several stems of a pink-flowered Loranthus nearly a foot
926 CXIII, LORANTHACES.
long; and again several low shrubs of the intensely glaucous Zamaria orientalis Forsk. had nearly all its principal branches decked with dense patches of the splendid yellow flowers of another Loranthus. The majority of the species in Angola have brilliant pink or scarlet flowers, but several have them golden or orange-coloured, and nearly all produce a profusion of flowers. The principal flowering season coincides in Angola with the spring, that is, from September till November, but many of the finest species continue their blooming almost throughout the summer, when they may be seen not uncommonly covered with ripe fruits at the base, while they are still in full flower at the top of the same branch. The yellow-flowered kinds, however, seem to begin their season much later, for several golden-blooming species open their flower in June and July, which in Angola is the very middle of the dry and cool winter. All the species have fleshy and rather broad leaves and vary considerably in colour, being in some species dark shining green, in others glaucous-green, and in a few species they are covered with a grey tomentum. Although some evince a decided preference for particular species of trees, not rarely the same species of Loranthus is found growing on trees belonging to quite different species or genera or even orders of plants; the pendulous Loranthus, however, was observed exclusively on a Ficus, while the Visewm affected only the arborescent Composite Tarchonanthus canvploratus L.
The forest trees most frequently inhabited by Loranthacee are Adansonia digitata B. Juss., several of the larger trees of the orders Leguminose, Combretacez, Sterculiacez, and Sapindacez, as well as many of the various fig trees, while in the southern parts of Benguella and near Cabo Negro many beautiful species of Loranthus may be observed on Tamarix orientalis Forsk. ; on the other hand a Loranthaceous parasite was never seen on trees belonging to the orders Anonacez, Hypericacee, Rutacex, or EKuphorbiacez, although each of these orders is rather copiously represented by large and mostly evergreen trees in the forests of the Angolan highlands. Scarlet-flowered species of Loranthus were frequently seen to infest introduced trees, such as the Orange, Lemon, and Ficus Carica L., and it seems that these curious parasites emigrate with a kind of predilection from their original habitations to neighbouring fruit trees; on one occasion a whole orchard of orange trees was invaded with a bloodred- flowering Loranthus, and in another instance most of the trees in a fig-plantation were covered with a grey-leaved and_yellow- flowering species; it seems also that the nature of the sap of the foster tree exercises little influence upon the vegetation of Loranthacez, for in several cases the same species grew with equal vigour on Adansonia which has a watery juice as on fig-trees of which the sap is milky and glutinous. This fact suggests the possibility and even the facility of introducing these pretty parasites into European gardens and conservatories, where they would furnish with their graceful forms a pleasing variety and
Loranthus | CXIII. LORANTHACES, 927
contrast. The species of Loranthus mostly prefer partial shade, while some like a denser shade and others again full light. Welwitsch suggested that an attempt should be made to cultivate the fine-flowered species of Loranthus on small orange or fig-trees ; the berries could be easily introduced from the west coast of Africa, or they might there, (say) in Sierra Leone or Lagos, be planted on small species of /icus, which these parasites especially affect, and they might then be forwarded together with the matrix in Wardian cases to Europe.
The most magnificent species of Loranthus are those which grow on Acacia and Tamarix trees, on account of the great contrast between the colour and foliage of the hosts and their parasites: for instance, LZ. Gilgit about Lopollo on a species of Acacia with yellow flower-heads and a fine pubescence, and L. cinereus and L. Meyert in Mossamedes on Tamarix orientalis Forsk. Sometimes, though rarely, a Loranthus grew in large masses on most of the trees of an extensive forest; such an occurrence was observed in February 1855, in Golungo Alto, where a forest was covered as it were with a cherry-coloured mat, all the tree-tops being overgrown with the richly coloured flowers of a Loranthus.

CXIV. SANTALACES.
Before Welwitsch’s time Santalaceze were thought to be absent from west tropical Africa; their discovery in Pungo Andongo and Huilla was therefore important, and is one of the best proofs of the relationship which exists between this flora and that of the Cape of Good Hope, where numerous species of Zhesiwm have been found. One of the species, 7’. virgatum Welw., has quite the habit of Thymelea arvensis Lam., while the rest of the Angolan species much resemble the European species of Thestwm, especially those with prostrate stems.

CXV. HUPHORBIACEA.
The plants of this order in Angola are distributed alike in the three principal regions, but with this difference, that each region has its predominant set of forms. In. the coast region the arborescent cactus-like forms, with the habit of Cereus or Hariota, are the most notable, and they communicate to their stations, where they are massed in forests, a very peculiar physiognomy. In the mountainous wooded region these leafless trees disappear, or they occur only in cultivation, and, instead of them, the forests and hills are furnished with climbing species of multiform aspect, at times resembling the Convolvulacez, as in the case of Dale- champia; the Urticaces, as in 7ragia, Acalypha, and Croton ; and the Leguminosze, as in some species of Phyllanthus. Arborescent forms do not fail to be represented, and such trees are in habit sometimes like the Tiliacee, Rhamnacez, or Lauracez, or even the Menispermacee. In the high plateau region there occur, in addition to some of the arborescent forms of the latter region, in other cases and in greater abundance the cactus-like euphorbias, representing, however, in this region by preference the fleshy Opuntia-like forms.
The timber of the woody species is nearly always of very good quality, white and firm, sometimes yellowish white, and then it mostly more or less resembles box-wood ; H'uphorbia Candelabrum and its allies are, however, exceptions to this general rule.
Two species of Euphorbia, namely 2. Candelabrum and E£. Tirucalli, in Loanda, as well as: Jatropha Curcas in Golungo Alto, provide the negroes with pitchers or stakes that take root readily when driven in the ground, and grow rapidly even where no other shrub or tree can live, and for this reason they are frequently used for making fences round the huts or villages of the natives,
A material for a black dye, called ‘“‘ Dunce,” is obtained from Alchornea cordata in Golungo Alto, and from Lepidoturus occi- dentalis in Pungo Andongo.
Tragia and Dalechampia contain stinging species; 7’. cordifolia stung Welwitsch after it had been kept ten years in his herbarium.
The milk which exudes from the species of Huphorbia is not so injurious as is often reported. On one occasion, when Welwitsch was shooting wild birds in Cacuaco near Loanda, the milky sap from £. Candelabrum was squirted in great quantity right into his eyes; but after washing them for ten minutes with cold sea- water, he suffered no affection of his eyesight. On another
940 CXV. EUPHORBIACES. [ Huphorbia
occasion Welwitsch’s Cabinda, while chopping off a large Poly- poreous fungus (cf. Fungus, n. 357) from the roots of #. Tirucalh, encountered a similar accident with the milk of the latter, but without any serious consequences. On the other hand, Monteiro, Angola, ii. p. 267 (1875), states that the acrid milky juice of the euphorbias is very dangerous to the eyes if it should drop into them, and that the natives employ the juice of Sanseviera angolensis Welw. as a remedy.
The negroes discriminate with tolerable exactness some of the species: for example, in Golungo Alto the natives call one species of Croton by the name of ‘‘ Mubango,” and another species ‘‘Mubango ia muxito,” that is, “ Wood Mubango”; and in Pungo Andongo a third species is called ‘‘ Mubango de Cabondo.” Tragia cordifolia was usually pointed out to Welwitsch as the “ Casaocio,” but they called by the same name the equally stinging herb Dalechampia scandens. In a similar manner the dye-plants, Alchornea cordata and Lepidoturus occidentalis, in Golungo Alto and Pungo Andongo respectively, are called by the name of “ Dunce.”

Welwitsch thought that this was a young form of his No. 632 (E. decussata E. Mey.). This determination is very doubtful ; perhaps the variety karroensis Boiss, l.c., that is, Arthrothamnus Burmanni Kl. & Garcke, Il.cc., pp. 251,62, represents our plant; or possibly £. serpiformis Boiss. in DC., l.c.

and our specimens, consisting only of foliage, are insufficient for certain determination ; they should also be compared with E. Teke Schweinf. ex Pax in Engl. Bot. Jahrb. xix. p. 118 (1894).
The following No., which is without flowers, should be compared with this species, though it is apparently distinct ; the prickles are straight, in pairs, distinct at the base, diverging, =}. to 1 in. long ; and the leaves are obovate and entire, and measure 3} to 4 in. long by 1} to 2 in, broad; it is referred to by Welwitsch, Apontam. p. 564 under n. 153; it should also be compared with a specimen in the Kew herbarium, collected near Regent by G. F. Scott Elliot, Sierra Leone Boundary Commission, n. 4112 :—
Pungo ANDONGO.—A small tree, 10 to 12 ft. high, a beautiful plant resembling EL. neriifolia L. ; trunk 3 to 4 in. in diameter, divided at the top into crowded ascending or spreading branches, which are angular, thick and leafy towards the apex; leaves obovate-lingulate, fleshy, glaucescent. In small open woods, on a sandy soil, at the bank

12. E. opuntioides Welw. ms. in herb.
Shrubby, glabrous or nearly so; stem low, branched at the base; branches ascending or decumbent, fleshy-woody, flattened- compressed, articulate, glaucous-green, about 6 in. long, leafless, remarkably resembling an Opuntia, 2 to 2 in. broad at the con- strictions; joints 1 to 1+ in. broad and long, sub-cireular or broadly obovate in general outline, undulate, coarsely crenate or repand on the darker sparingly spiny margin; spines rather slender, dusky, seated at the apex of the undulations or crenations, usually in pairs, distinct at the base, erect or diverging, straight or a little curved, deciduous, } to 3 in. long; cymes short, inserted in the shallow depressions at the apex of the subtruncate termina! joint of the branches, erect, 3- to 1-headed; common peduncle thick, $ to % in. long, with two opposite broadly ovate obtuse or rounded bracts at the apex, secondary peduncles thick, the lateral ones 4 to } in. long divergent, the middle one shorter ; middle involucre sub-hemispherical, somewhat compressed, + in. broad, bibracteate at the base; lateral involucres rather smaller, about 3 in. broad ; the bracts broadly ovate or semicircular, nearly equalling the involucre in height, concave, adpressed ; lobes of the involucre short, fringed at the apex; glands very short, broad, crenulate on the margin; bracteoles among the filaments fringed at the apex; pistil sessile or very nearly so, glabrous; styles united one-third way up from the base, diverging above, shortly cleft at the apex; ripe carpels about + in, long; seeds + in. long, smooth,

little angular, branched from the base; branches decumbent, ascending, crowded, articulated-constricted ; branchlets 2 to 4 in. thick at the constrictions; spines strong, straight, ranging up to 3 in. long, diverging in pairs arising from elevations along the angles of the branches, the apices of the elevations about } in. distant from each other on each angle, the bases broad and confluent; joints 14 to 12% in. long, the angles few, produced into fleshy compressed wings; wings thick, semicircular or semi-elliptical, sinuous-dentate on the margin, spreading to a distance of + to 3? in. from the axis of the branchlet ; teeth 3 to 5, broad, obtuse, shortly or obsoletely spiny at the apex; the youngest branchlets very glaucous.
MossAMEDES.—In sandy hilly maritime places, from the river Giratil to Cabo negro, very plentiful, not uncommonly occupying almost exclusively extensive tracts of country; with few fl. July 1859. The bulk of the specimens collected were lost in the war with the Munanos, and only rudimentary pieces remain. No. 643.
This belongs to the section Diacanthium, and apparently is related to EL. Lemaireana Boiss. and E. antiquorum L.; it is perhaps the succulent Euphorbia which frequently forms the matrix of Hydnora africana 'Thunb. (Welw. herb. n. 530) and is ultimately killed by it. This also is probably the cactus-like Zuphorbia, occurring to the south of the town of Mossamedes in July 1859, which was beset with the rare fungus n. 147, Tulostoma angolense Welw. & Currey in Trans, Linn, Soc. xxvi. p. 290, t. 20, figs. 10 and 11 (1868); also the de- cumbent Euphorbia which bore Lichen n. 420, Roccella linearis var. primaria Wain (see Welw. in Journ. Linn. Soc. v. p. 183), together with species of Ramulina (cf. Lichen n. 23) in July 1859 near the town of Mossamedes; also in the midst of which grew Emilia albocostata, ante p. 596, Welw. herb. no. 3573. It must also be compared with L. triangularis Desfont. Cat. Fl. Hort. Paris., edit. 3, p. 339 (1829), name only, a plant supposed to belong to the Cape Flora.

Punco ANDONGO.—A fleshy, tenacious shrublet, 1 to 13 ft. high ; prostrate-ascending or the stems at first erect, soon becoming decumbent, 3- to 6-angled, articulate-moniliform, glaucous-green, leafless, the younger ones 2- to 4-angled ; branches erect-spreading, 4- to 6-angled ; the angles spiny-toothed ; the whole plant abounding in a caustic milk ; flowers yellow. On the gneiss rocks of the Pedras Negras in the presidium, chiefly on their very dry slopes, in company with species of Xerophyta (cf. X. squarrosa Baker ; Welw. herb. 1555 and CoLt. Carp. n. 1006), Commelinacese, etc., plentiful ; fl. Jan. and Feb. 1857; also a young plant near Catete, Feb. 1857. No. 639.
Hviitia,—A shrublet, 7 in. high or less, articulately branched from the base, in form resembling an Opuntia; flowers yellowish. On mica-schist rocks, among bushes, at an elevation of 5000 ft., between Lopollo and Nene, sparingly ; very few specimens in fl. Feb. 1860. No. 640.

LoanpA.—A tree, 15 to 45 ft. high, and more, in the form of a candelabrum, constituting dense forests in dry, hilly, maritime, and rocky places, but sometimes solitary ; trunk straight, 1 to 2} ft. in diameter ; bark cracked ; branches subverticillate, ascending-arching ; branchlets verticillate ; trunk and branches 3- to 8-angled ; branchlets mostly trigonous; flowers red, very crowded, as well as the whole plant much abounding in milk. Plentiful; fl. July and Aug. 1858. Around Cacuaco, where it grew in company with Lissochilus calopterus Reichenb. f., it was usually more than 50 ft. high, with a stem 23 ft. in diameter; beginning of Jan. 1854; near Mutollo, 23 July 1854; Loanda, 17 June 1858. A characteristic tree, producing a very fine effect. No. 641.
Stakes cut from this tree and planted easily take root and grow quickly ; they are thus used by the negroes for making fences around their dwellings.
The lichens n. 211, Tremotyliwm angolense Nyl., n. 164, Lecidea episemoides Nyl., and n. 399 (?) Opegraphia graphidiza Nyl., also n. 189, grew on the old trunks of this tree : see Nylander, Lich. Angol. Welw. pp. 8, 10, 12 (1869) ; lichen nn. 320, 414, 413, 399, 398, 328, and 350 at Boa Vista. Barleria salicifolia S. Moore, Welw. herb. no. 5119, grew in little woods composed of Euphorbia, probably this species, about Libongo.
It is doubtful whether this is the same species as EL. Candelabrum Tremeau ex Kotschy, Allgem. Ueberbl. Nillind. p. 13 (1857) in Mitth. Geograph. Gesellsch. Wien., Jahrg. i. Heft ii. p. 169; Kotschy, Umr. Uferl. Weiss. Nil, p. 23 (1858) in Mitth., /.c., Jahrg. ii. Hefti. p. 92 ; Boiss. in DC., l.c., p. 84; Petherick, Trav. Centr. Afr. i. p. 308 (1869). It is probably the gigantic Euphorbia mentioned by Welwitsch in Proceed. Linn. Soc. ii. p. 328 (1854) as forming woods at Loanda, just as Pinus sylvestris does with us, and readily discernible even from shipboard.
The following Nos. perhaps belong to this species of Welwitsch :—
Punco ANpDoNGo.—A little tree 10 to 12 ft. high, or rarely 15 ft. ; trunk straight, subcylindrical, 3 to 4 in. in diameter, hard-woody, spiny-tuberculate ; branches and branchlets spreading-ascending, 3- or rarely 4-winged, glaucous-greenish, leafless. By rocks near Mangue and Candumba, plentiful ;' without fl. March 1857. No. 6410. A tree of 12 to 15 ft., candelabriform, with acutely trigonous ascending branches and branchlets. By schist rocks in wooded places near ae on the road leading to Candumba ; without fl. March 1857. INO. of.
Bumpo.—A tree, 20 to 40 ft. high; trunk straight, cylindrical, much branched towards the apex, with the bark cracked as in Picea ; branches suberect, as well as the branchlets triquetrous and glaucous ; spines purple, venomous or certainly suspected. In the rather dense rocky primitive forests of Serra de Xella; without fl. June 1860. Only one specimen. No. 636.
GoLtunco ALTo.—Arborescent. At Bango; fl. only 7 and 8 Sept. 1855. Local name “ Quisoma.” CoLu. Carp. 932.
“Insomma” is the name of an arborescent Euphorbia, which grew on the banks of the Zenga, and is probably another form of the name “‘Quisoma.” <A tree Huphorbia, to which Welwitsch referred by the name of “ Quisoma” in his diary of 6 Sept. 1857, occurred at Funda in the district of Icolo e Bengo. It occurred also in the Libongo district in company with Acacia Welwitschii Oliv., ante, p. 310,

The following No. has the appearance of this genus, and is possibly the variety myrtifolia of B. sempervirens L. Sp. Pl. edit. 1, p. 983 (1753) ; being without fl. or fr. it is uncertain :—
Huitta.—A shrublet nearly glabrate or minutely, puberulous especially on the tetragonal branchlets and on the very short petioles, 1 to 3 ft. high, with the habit of a Box, glaucescent ; leaves apparently evergreen, somewhat glossy, coriaceous, elliptical ovate or lanceolate, wedge-shaped at the subsessile base, more or less obtuse at the apex, 3, to 1 in. long by } to 2 in. broad, recurving along the margin, with numerous inconspicuous veins and the midrib prominent beneath. On the rocky ridges at the top of Sierra de Xella not far from Mumpulla, about 4000 to 4100 ft. alt., Oct. 1859 and June 1860, abundant. No. 409.
The wood is like that of the ordinary Box.
The plant should be compared with B. benguellensis Gilg in Engl. Bot. Jahrb. xxviii. p. 115 (15 Dec. 1899), which belongs to Huilla, but an authentic specimen of which I have not seen.

The sap is thin and whitish at first, but soon coagulates and turns yellow-dusky and glossy like resin ; the fruit is said to be edible, but this statement is very doubtful. The native name is “ N-bulla.” Welwitsch collected his specimens and hastily examined them during the Monano war ; he added that the calyx-segments pass gradually into the petals so that it becomes very difficult to decide precisely what belongs to the calyx and what to the corolla; only the two |
Uapaca | CXV. EUPHORBIACEA. 965
outer calyx-segments are calycine. In the description of the parts of the flowers given above, the terminology used by Welwitsch has been followed ; though perhaps the flowers would be better regarded as apetalous.
“'N-bila” is the name of the fruit of a small tree which occurs between Lombe and Condo in Pungo Andongo; it is the size of a walnut and the taste is very sweet and aromatic.

villages, plentiful, after the manner of elms in Europe, thriving well in Sobato de Bumba; fl. and young fr. 22 Oct. 1855. No. 348. A tree of moderate size, with discolorous leaves and racemose moncecious flowers. At the outskirts of forests near Sange, fr. ; also frequently cultivated. Cou. Carp. 930.
This tree is a frequent ornament of the hilly borders of forests on the interior plateau of Angola, particularly in the districts of Golungo Alto, Ambaca, and Pungo Andongo ; it varies, according to the nature and humidity of the soil, etc., in the breadth and even in the silky lining of its leaves; the younger plants and the shoots from the stumps of old trees always have broader leaves, and the stipules are more luxuriant ; the largest leaves fall off at the time of flowering. The negroes of Golungo Alto call the tree “Mubango” ; and the root, as well as the brown gum which exudes from the trunk, is used by the native medical men as a drastic purgative, in the form of a decoction together with that of the root of Mundondo (cf. Chlorocodon Whiteii Hook. f. and Tylophora conspicua N. E, Br.). A decoction of the rind of the root, mixed with the leaves or stems of Mobiro (cf. Adenia lobata Engl.), is an excellent anthelmintic remedy. (See Welw. Synopse Explic. p. 32, n. 78, p. 37, n. 99, p. 56, sub n. 146). The dose as a purge is a teaspoonful of the Mubango powder for an adult person. The wood is white and firm, but easily cracks ; when in flower the tree is much frequented by bees; the fruit is tricoccous and nearly the size and colour of a medlar. Welwitsch very highly recommended this tree for planting at Loanda on account of the excellent shade which it affords and because it thrives well in a parched nearly rainless climate and not less so in a rich soil; it remains to be proved whether it dislikes the seaside.
In Loanda the name “ Mubanga” or “ Mubango” is used for a very different tree, namely, Acacia Welwitschii Oliv. ; Welw. herb. no. 1806. According to Welwitsch’s ms. the Euphorbiaceous Mubango is a common tree in the district of Pungo Andongo.

This is the most valuable among the cultivated plants of the family in Angola; it is extensively cultivated in all parts of the province, and provides the bread of the negro population ; it is also eaten in the raw state, just as it is removed from the soil, without even the least injurious results ; it consequently can there contain little or none of the poisonous principle which appears to abound in the greater part of the varieties of the species or of the allied species which are culti- vated in tropical America. See Welw., l.c., p. 564. The very fine meal which is obtained from the roots is called ‘“‘ Fuba,” “ Fuva,”’ or ‘* Fuba ia N-bombo; ” and in course of its preparation sieves (those of an Egyptian pattern are called ‘‘ Mussalo”’ or “‘ N-salo” [?]) are used in the mountainous districts of Golungo Alto, Ambaca, etc., made from the textile plants called “Subi,” that is, Donar purpurea K. Schum. and Phrynium textile Ridl. The tubers are called ‘ Caringa.” Fuba, mixed with the pounded root of Amomum erythrocarpum Ridl., is a remedy for pains of the abdomen.
Manioc is almost wild in the Quilombo-Quiacatubia forests in Golungo Alto, where it occurs as a shrub 9 ft. high; but its root is then by no means thick, and is scarcely edible owing to its bitterness. In Pungo Andongo the fuba meal is made into dry cakes, which keep a long time and are called “ Quiquanga,” or ‘“‘ Quicoanga,” or “‘ Bombé.” “ Quinbombo” is a fermented drink prepared from mandioc and other meal ; it is also called ‘‘ Pombe,” and when sweetened with honey it is called “ Cassiilo.”
The negroes of Sange purposely throw into the adjacent streams, the Cuango and Quiapose, roots of mandioc, in order to make the waters more tasty ; the putrid smell thus produced causes the other inhabitants to fetch their drinking water from the small spring of Quiquele-quele on the north-west of the town. At Loanda. the plant is called “ Quisaca.”
The word JMandioca, although used at times by the people of the interior of Angola, is not strictly derived from the Bunda language, but, according to José Villela de Barros (Memor. da Ac. R. d. Sc. de Lisboa, vol. vii.. Mem. Corresp. p. 52, 1821), belongs to the idiom of the American Indians, and is compounded of mandi = house, and oca = bread. There are two varieties of the plant, one called mandioca branca or white mandioc (caxord), and the other mandioca roxa or purple mandioc, that is, with violet-red petioles and stem.

The negroes call this plant “‘ Risanza,” and the Portuguese colonists call it ‘‘ Casiocéo.” The failure in rearing horned cattle in Golungo Alto is said to be due principally to the frequent presence of this terrible stinging plant ; Welwitsch, however, doubted this statement ; it probably causes cattle to avoid the pastures in the same way as does Lepistemon africanum Oliv.

Our specimens are not quite like the type from Tahiti; though the plant is described by Welwitsch as annual, the stems sometimes. throw out adventitious roots near the base ; the leaves (including the acumen) are strongly serrate-dentate, 1 to 44 in. long by 4 to 14 in. broad, acutely acuminate, more or less conspicuously marked with linear cystoliths, and glabrous except the midrib and principal veins beneath. I prefer to consider them as representing a variety of the above variable species, but on the scale of species as treated by Weddell it might be regarded as new. Cf. Henriques, Bol. Soc.

Gingos “ Liambe”’ ; the Portuguese name is ‘ Canhamo.” This com- modity, which is for the most part if not wholly composed of the cut- up leaves of hemp, is eagerly sought for in the markets by the natives at Loanda and in all the interior of Angola for narcotic smoking ; indulgence in it constitutes one of the most pernicious of their vices, especially with the slaves, who when addicted to Riamba smoking become nearly useless to their owners. The plant is cultivated in all the interior districts of Angola, but always in situations more or less retired or lonely, in order to withdraw the plantations from the notice and greed of passengers. Hemorrhage of the nose is the very frequent consequence of this smoking intoxicant ; the natives in the interior of Huilla are accustomed to cure it with the powdered panicles of ‘“‘Encotahote ” (Cymbopogon schenanthus Spr. var. stypticus Rendle ; Welw. herb. n. 7526, Coll. Carp. 1093 and 1094), an application of which nearly always has the desired effect.

The dried herb is packed for sale in cylindrical sausage-shaped parcels, 2 to 3 ft. long and about 4 in. thick. The fruits of the Adansonia, called “‘ Mticua,” are used by the negroes for smoking the Riamba ; see ante, p. 80.

Some species of figs are especially rich in a thick glutinous milk, which is used by the negroes in the preparation of a bird- lime, called Molemba ordinaria ; other species, such as /’. Quibeba, supply a tough and firm wood, useful for the manufacture of domestic articles; and some, such as /, trichophylla and F. pstlopoga, belong to the most stately trees of western tropical Africa, both on account of their large-leaved and widely extended heads with brick-red branches, as well as for the abundance of their peach-coloured figs, with which they are laden twice a year, and which are tolerably juicy, somewhat sweet and used by several colonists for the extraction of a very excellent spirit tasting like a superior gin. Welwitsch considered that enterprising men with the necessary knowledge and a moderate amount of capital might, in consequence of the great fruitfulness and frequent occurrence of the trees, make this a profitable branch of industry. Other fig trees again have aérial roots, which are coloured red during the rainy season, and which hang down from the branches to the extent often of 10 to 12 ft. and produce an exceedingly strange appearance enhanced considerably by the presence of their in- numerable cherry-like figs.
Many other species grow as parasites, either rising clear from the branches of some other tree, or, embracing the tree with its stem pressed flat like a covering, sooner or later kills it, and then the fig tree, previously often only a half open tube, closes at the top and starts with an entire stem its independent existence.
The leaves of F. exasperata Vahl, are used for polishing purposes.

The following No. should be compared with this species, but I have not had the opportunity of examining the structure of the receptacle :—
GoLtunco AuLtTo.—A strongly lactescent tree of moderate size ; branches spreading, also nearly horizontal; branchlets smooth, glabrous ; leaves alternate, oval or broadly ovate, entire or slightly sinuous-repand, very shortly and obtusely or abruptly acuminate at the apex, broadly and unequally or slightly hollowed at the 5-nerved base, coriaceous, smooth, glabrous, glaucescent-green above, light green beneath, 9 to 11 in. long by 53 to 7 in. broad ; principa! lateral veins 6 to 12 on each side in addition to the basal nerves, in clear relief beneath ; tertiary and net-veins close, in relief beneath ; interspaces minutely scaly-pulverulent beneath, minutely pitted above; petioles stout, smooth, glabrous or puberulous, 24 to 32 in. long ; receptacles large, the size of a pigeon’s egg, 14 in. long by 2 in. thick, ellipsoidal, puberulous, subsessile, dusky, laterally bracteate at the base. In shady forests around Bango, Quilombo, and Canguerasange, not un- common ; also on sunny declivities ; fr, Nov. 1854. No. 6398.
The fungus n. 74, Phyllachora repens Sacc., A, L. Sm. in Journ. Bot. 1898, p. 178, grew on the leaves of a species of Ficus, probably this plant, at Sange in Nov. 1854 and July 1856.

addition to the basal nerves, sub-parallel, anastomosing near the margin ; net veins intricate, close, in relief beneath ; petioles angular, puberulous, 11 to 4 in. long, of nearly the same thickness throughout ; receptacles very crowded, proceeding from the thicker branches and even from the trunk, obovoid, warted, as large as a pigeon’s egg, shortly pedun- culate. In dense thickets among the Queta mountains, sporadic ; in leaf, without fl. or fr. extant on the specimens, beginning of June 1855. The fruit was seen by Welwitsch. No. 6399.
Dr. Warburg, /.c., p. 155, regarded this No. as probably a form of F. Vogelii (Miq.). The native name is ‘“‘Quibeba.” The lichens nos. 213, 252, 381, grew on the trunks of F’, Quibeba.
This tree supplies a tough and firm white wood, which is manu- factured into bowls and such-like domestic articles; the trunk is straight and usually 4- to 6-gonal as if consisting of 4 to 6 trees grown together (as occurs also in several other specimens of this genus) ; and the head forms a broad majestic crown. The tree frequently has growing upon its branches plants of Hariota parasitica O. Kuntze (ante, p. 407), Loranthus, and orchids.
5. F. callescens Hiern, sp. n.
A small tree, 12 to 20 ft. high, very much branched, ever- green; trunk and branches sparingly or copiously lactescent ; branches spreading, dusky or ashy, glabrous, smooth, somewhat angular; branchlets pendulous after the habit of Salix babylonica L., clavate-thickened towards the apex, densely clothed with the persistent stipules, leafy; leaves alternate, obversely lanceolate or obovate, cuspidate or spiculate at the apex, wedge-shaped to the unicostate base, very thick, dryly coriaceous, hard, very rigid, glabrous, green glossy smooth and punctate with raised points above, pallid and delicately reticulate beneath, sometimes not lactescent and even in the living state nearly dry, 3 to 74 in. long by 1 to 21 in. broad; principal lateral veins 6 to 10 on each side of the strong midrib, slender, clearly marked beneath, inconspicuous above, spreading ; net veins pale, sunk in com- paratively broad depressions which are often punctate with raised points ; interspaces beneath slightly in relief rather darker and minutely dotted; petioles broad, + to 14 in. long, sometimes not lactescent, smooth, pulverulent with minute dots or glands ; stipules ovate, + to 2 in. long, reddish, soon turning brown, very abundant, imbricate, pulverulent-puberulous on the back, delicately pluricostate; receptacles rare, pyriform, hollowed or depressed about the apex, obtusely umbonate, shortly hairy and scrobiculate outside, + to 14 in. long. thick-skinned ; interior about 2 in. long by + to in. in diameter ; basal bracts % to } in. long, stipuliform ; coat inside somewhat porous or spongy but firm ; peduncles to 14 in. long, axillary, solitary; male, female, and neuter flowers in the same receptacle; perianth 4-partite ; segments narrow; ovary narrow; style terminal, rather long; stigma bipartite; stamens solitary; filament long, slender ; anther short, dusky.

The lichen n. 287 grew on the leaves of this species at the spring of Quiquele-quele in August 1855,
This is nearly related to F. Preussiit Warb. l.c., p. 156, but the leaves.
in our plant are more regularly wedgeshaped towards the base and are smaller ; their venation is similar.
The following No., with laurel-like foliage, differs from F. callescens by having the lateral veins of the leaves much more numerous, etc.
6. A huge tree, 50 to 80 ft. high, full of a thick milk; head depressedly hemispherical, very broad; branches spreading, bending sometimes upwards sometimes downwards ; branchlets. ashy, smooth, glabrate or inconspicuously pulverulent, curving, rigid, leafy especially towards the apex; leaves alternate, entire, obovate-oblong, obtusely subcuspidate at the apex, rounded or obtusely wedgeshaped at the inconspicuously 3- or 5-nerved base, coriaceous, hard, smooth, glabrous, very rigid, deep green glossy and with elevated rounded points above, paler beneath, 4 to 7 m. long by 1} to 2} in. broad; midrib thick, prominent beneath ; lateral veins numerous, parallel, patent, slender 3. reticulation minute, plainly marked beneath ; interspaces marked beneath with small papillose points; petioles thick, } to £ in. long, smooth; stipules deltoid-ovate, glabrous, 4 to + in. long, caducous.

IsLAND OF Sr. THomMaAs.—Without receptacles, Dec. 1860. Called ‘‘Mussanda.” The bark supplies a dye. No. 6405.
The leafy branches agree well with a specimen with fruit in the National Herbarium collected at the Cape Coast by Brass, which appears to belong to this species, but I have not seen a type specimen.
The following five Nos. may be compared with this species, but some at least of them are apparently distinct.
ZENZA DO GOLUNGO.—-A shrub. On a rock near Tanderachique ; without receptacles, Sept 1857. No. 6400.
This is probably the Ficus mentioned by Welwitsch in his diary 27 Ang. to 7 Sept. 1857, as a bush with a widely spreading head thickly coriaceous leaves and pendulous or reflected fruit, occurring at. Tanderaxique, but very rare.

GoL_uNGo ALTo.—In Sobato de Bango Quilombo and about Muria, occasional; ripe fr. Jan. 1855. No. 6391. At the outskirts of secondary woods near Banza de Bango ; without fl. or fr. Jan. 1855. No. 6393. Chiefly in the elevated forests of Quilombo Bango, more rarely by thickets near Trombeta ; unripe fr. Aug. 1855. No. 6392.
The native doctors call it “ Lucanda ” ; it is one of species of the genus called by the collective name of ‘‘ Molemba.” A very small species of Cynips chooses this plant by preference for its abode.

In wooded not very damp places in the district (and in Ambriz) ; fl. and fr. Sept. 1858. No. 6357.
‘ Zandeiro,” perhaps a corruption of “ Nandeira,” is the local name of this tree in Libongo.
The following No. has larger leaves somewhat cordate at the

BarRA DO Danpe.—Aérial roots turning a blood-red colour, juicy, largely used by the natives as a styptic medicine. Trees were seen in some instances in fruit with foliage, in others in fruit without foliage, and in others again in leaf without flower or fruit, all these cases in the same place and at the same time, Nov. 1853. No. 6352 partly.
LoanpA,—Cultivated in the public walks at Loanda ; fr. May 1854. No. 6352 partly.
GoLtunGco ALTo.—A handsome evergreen tree, 30 to 60 ft. high ; head broad, ovoid-oblong ; branches patent, throwing out very crowded aérial roots which hang down vertically and when they reach the ground take root and give rise to fresh trunks, the latter at length attaching themselves in an arching manner to the mother plant; receptacles turning red, equalling small cherries in size, eaten by the negroes. In primitive forests throughout the wooded mountainous districts ; among the Alto Queta mountains; fl. and fr. May 1856. No. 6352 partly. An extensive tree, with long red beards, that is, furnished with reddening aérial roots issuing from the lower side of the branches ; leaves coriaceous, shining, sometimes deciduous, some- times evergreen; receptacles 2 or 3 together, sessile, turning red, equal to large peas in size, At the outskirts of forests, about villages, etc. ; fl. and fr. May 1855. No. 63851. A tree, 25 to 35 ft. high ; head ample; trunk angular below, straight, furnished with red beards ; leaves thickly coriaceous, very highly shining, with red midribs ; receptacles like cherries in size and shape, turning red, soft ; pulp viscid ; seeds numerous. In the primitive forests of Bango and Quilombo, also in Sobato de Bumba; fl. and fr. beginning of Noy. 1855. No. 6349.

The Portuguese colonists call it ‘‘ Incendeira,” a name which the negroes corrupt into “‘ Sandeira.” The native name in Golungo Alto is “ Mulemba” or ‘‘ Molemba” or “ Malemba,” in plural ‘“ Milemba ” ; it is indigenous also in the virgin forests of Ambriz and Cazengo nearly everywhere but sporadic, and it is frequently cultivated about villages ; a decoction of the Mulemba beards, that is the aérial roots, is employed by the natives in eruptive fevers and diarrhoea, and it is also used externally to wash ulcerating sores. The medicinal virtue of it appears to depend upon an astringent principle in which it abounds ; the natural colour of these roots, when fresh, is blood-red with a peculiar lustre almost coppery, and their size often exceeds a yard and a half ; they hang down vertically from the lower branches of the trees in the form of purple besoms. See Welwitsch, Synopse Explic. p. 28, n. 63 (1862). It affords the principal nourishment for a water-distilling Cicada, and is the favourite haunt of very beautiful Cetonias. Combretum flammeum Welw: herb. nn. 4297, 4351, ante, p. 344, grew in Molemba groves in Golungo Alto in Nov. 1854 and Oct. 1855; and lichen n. 438 grew on this fig at Sange in May 1855 ; also the fungus n. 50 at Canguerasange in Noy. 1854 on the trunks.

A tree, 20 to 40 ft. high, patently branched, loosely frondose ;
Ficus | CXVII. MORACE. 1011
sap watery, viscid; bark grey; branchlets scabrid ; leaves alter- nate, ovate or somewhat oval, shortly acuminate at the apex, rounded or emarginate at the base, firmly membranous, very scabrous on both faces, not pubescent, denticulate or repand along the general outline except near the base, somewhat glossy above with a peculiar lustre, paler beneath, deeply or acutely palmate- lobed in the case of young plants up to the third to fifth year of age, 2 to 6 in. long by 1 to 4 in. broad, trinerved at the base ; principal veins about 3 or 4 on each side in addition to the basal nerves, strongly marked beneath, feeble above, their branches more or less transverse and passing by degrees into a delicate but not conspicuous reticulation; petioles + to 1? in. long, scabrous ; stipules scabrid on the back, broadest at the base, lanceolate, smooth inside, acute, pallid, $ to } in. long, deciduous ; receptacles spherical, a little smaller than a hazel nut, about } in. in diameter or less, scabrid, in pairs, pedunculate, on the branchlets or young lateral shoots, from yellow to red when ripe, 4-bracteate with two of the bracts attached to the base and the other two opposite to them and attached near the middle of the receptacle; osteole closed with 3 to 5 small ovate obtuse bracts; peduncles from } to less than $ in. long, scabrid, often bracteate with short obtuse bracts. All the receptacles examined had female flowers only, with long slender styles and stigmas.
GoLuNGO ALTO.—In the more elevated forests and at the sides of hills about Bango, Canguerasange, Cambondo, and Trombeta, plentiful ; fl. 3, 7, and 25 Nov. 1854. No. 6387. A tree, at the Governor’s house at Sange, supposed to be ornamental; fl. beginning of Oct. 1855. No. 6411.
The extremely rough leaves are used for polishing purposes and called “‘ Lixa”’ ; the tree is called “ Lima” (a file). The fungus n. 76, Phyllachora repens Sacc., grew on the leaves.
The branches, even when a foot thick, readily take root, when driven into the ground ; the trees afford excellent shade, and on this account they are frequently used for avenues, etc.,in public places. The wood is good and white ; the natives of Golungo Alto call it “* Mucacasa.” ;
This is probably the species of Ficus referred to in Bowdich’s Mission to Ashantee (1819), p. 445, and locally named ‘‘ Egoégoo” ; the leaves were used in planing wood, polishing and cleaning various articles of household furniture, and feel like emery paper.
Tt is difficult to separate this species from JF’. asperifolia Miq., L.c., t. 15, fig. B, especially as in No. 6387 the leaves are polymorphous ; the perianth lobes are ciliolate, and in this respect agree with the figure quoted above for F’. exasperata. With the original description Vahl’s trivial name is misprinted axasperata, but this is corrected, /.c., p. 402, and in the index at the end of the volume it appears as corrected.

This variety ought, perhaps, to be kept as a distinct species ; it is probably the species of cus, mentioned by Tedlie in Bowdich, Mission to Ashantee, p. 371 (1819), as one of the medicinal plants of that country, it being there called ‘“* Adumba.”
The following No. possibly belongs here :—
ISLAND OF St. THoMaAs.—A tree ; trunk straight but little branched ; head widely spreading but sparingly dense ; nerves of the leaves and stipules almost like those in the genus Jacaranga (Euphorbiacee).

May 1855. No. 6342. At Carengue among the Queta mountains ; without fl. or fr. July 1856. Apparently this species. No. 6414. |
It was apparently on the living leaves of No. 6335 that the Fungus n. 2, Phyllachora irregularis A. L. Sm. in Journ. Bot. 1898, p. 179, grew among the Alto Queta mountains in March 1856. “ N-guiriri” is the native name of a tree referred in Welwitsch’s mss. to this species.
The two following Nos. should be compared with this species :-—

The fruit is described in Welwitsch’s notes also as like a plum and yellowish red or light yellow-rosy. In primitive forests at the base of Serra de Alto Queta, sporadic, flowering nearly throughout the year, fruiting principally in June ; fl. and fr. May to July 1856. No. 456. A small tree; branches and branchlets very patent, almost pendulous, bright purple. In wooded places at the banks of the river Cuango near Sange ; without fl. or fr. Feb. 1855. Foliage rather larger and thinner than in the last no. No. 457. In dense primitive forests at the great cataract near Sange ; fl.-bud Aug. 1855. No. 458.
The native name of No. 456 is “Munguenga id muxito” or ‘““ Munguengo ia muchito,” which means the Munguenga of the woods; this name according to Ficalho, /.c., is equally applied to Spondias, which has a fruit similar in taste ; S. Mombin L. is called ‘“ Muguenga”’ or ‘ Muguengue.” See ante, pp. 175,176. The aspect of this Bosqueia is much like that of Mesogyne insignis Engl. Bot. Jahrb. xx. p. 148. t. 5, fig. M-V (1894) as judged from the plate quoted. The Orchid Angrecum Guyonianum Reichenb. f., post, ii. p. 9, grew on “ Munguenga id muxito”’’; also the Fungus (?) n. 34, and Fungus n. 79, and probably lichen n. 362.

All the specimens seen were dicecious. In the primitive forests of the Alto Queta mountains, sporadic or in some places plentiful ; fl. in Feb. and March, young fr. in April and May, ripe fr. in July to middle of Aug., 1855 and 1856, first seen on the northern slopes of Cimeterio do Alto das Cruzes. No. 2593. A lactescent tree, with the habit of Mucamba-Camba (Chlorophora excelsa Welw. herb. no. 1559) ; fruit ficiform, velvety- scarlet. Cimeterio; fr. July 1857. Cou. Carp. 905.
Welwitsch and his negro servants frequently climbed some of these trees to cut flowers and fruits, but suffered no bad effects.
The leaves in the above No. are entire or somewhat repand but not serrulate, and glabrous or nearly so as well as the branches; but Sir Joseph Hooker in Fl. Brit. Ind. v. pp. 537, 538 (1888) describes the leaves as entire or serrulate scaberulous glabrous or tomentose beneath, and the young leaves as lanceolate serrulate hirsute ; and he states that, according to Dalzell, the leaves on the shoots are very different from the old ones, being densely hirsute elliptic-lanceolate caudate-acuminate and serrulate ; and that similar but much larger leaves occur in Malayan specimens ; the following Nos., therefore, should be compared with this species, and perhaps belong to it :—
GOLUNGO ALTO.—A small tree, with similar habit and in company with the above, near Sange, but never seen to flower, July 1855. No. 2595. <A tree, 8 to 10 ft. high, perhaps a young state of a larger tree, copiously lactescent. In damp forests at the cataracts of the river Cuango, near Sange, sporadic; the trees were never seen to flower, though Welwitsch lived near them for months, Aug. 1855. Negro name “ N-dua.” No. 1232. A tree, 6 ft. high, probably young, with the habit of a Ficus. In the secondary woods of the Central Queta mountains ; without fl. or fr. June 1856. No. 1232.

The fruit (syncarpium) is brought to market whole, and is often much larger than a man’s head, green on the outside with a soft rind ; the interior is full of a soft pulp (like half-baked bread), in which the seeds are embedded ; the seeds are about an inch long. The fruit is sliced and cooked in oil like the last species, which, however, makes a preferable dish. The inhabitants call the tree “ Jaca” or “ Jacca.”

In the denser damper forests of the island, up to elevation of 2500 ft., wild, and on account of its savoury fruit occasionally cultivated; fr. Dec. 1860. Native names “Isa,” “Isaquente,” ‘“Quicange,” ‘“ Giquenge,” or “Gicuenge.” No. 2589 and Cou. Carp. 20.
In Senegambia it is called ‘‘Okwa” or “Ocua.’’ It is mentioned by Welwitsch in Synopse Explic. p. 54, n. 142 (1862), under the name of ‘‘ Amendoas de Disanha”’ (Disanha almonds) ; the fruit is described as having the shape and size of a small “abobora chila” (Cucurbita ficifolia Bouché, ante, p. 402; Welw. herb. no. 834 and Coll. Carp. 142) ; the seeds are frequently sold in the market in the island of St. Thomas, where they are bought for food.
The fungus n. 73, the moss n. 148), the hepatic n. 302, and the lichens nn. 97, 180, 305, and 434, grew on the trunk branches or leaves of Dizanha in Serra de Alto Queta and in other parts of Golungo Alto. Carpolobia alba G. Don (ante, p. 48) grew under the shade of this tree then in flower-bud at the end of Oct. 1855.

In the island of St. Thomas, the name “ Oca” or “ Oqua,” is used to designate Ceiba Casearia Medic., ante, pp. 80, 81.

GoLunco ALTo.—A shrub or low tree, 4 to 8 ft. high, erect, spar- ingly but really lactescent ; stem branching a little above the base ; branches sparse, virgate, patent, elongated, slender ; leaves large, elliptical, long-acuminate, slightly rough, evergreen, subcoriaceous, dark green and glossy (the older ones opaque) above, pale green beneath ; receptacles on erect axillary stalks, solitary or 2 or 3 together, ob-pyramidal, embedded in pulp, the young ones capituliform, involucrate with 5 to 7 broadly ovate acuminate green scales, which are fringed on the red margin and converge adpressedly at the top of the capitulum ; the scales at the time of the flowering mostly deciduous, one or two afterwards conspicuous at the outer face of the receptacle, and the top of the capitulum spreading into a circular somewhat flat whitish fleshy torus, the margin more or less unequally erose-undulate or crenulate. The male flowers very numerous, at first 5 of them appearing around the female flower, afterwards always in a greater number, and finally covering the whole plane of the receptacle, each of them consisting of a very short cylindrical tube, entire at the mouth,, from the bottom of which rises the single whitish somewhat fleshy stamen; anther didymous, whitish, quickly turning dusky. The female flower solitary, central, consisting of an ovoid ovary, with a style bifid at the apex and only the flattened lobes exserted, sessile at the base of the receptacle, and rising through the cavity of the fleshy torus to its surface. In very dense exceedingly shady primitive forests, preferring the neighbourhood of streams, especially about the Capopa cataract, between Sange and N-delle, plentiful ; fl. abundant throughout the year, fr. only seen on one branch, 4 Oct. 1854 and June and Aug. 1855 and 1856. No. 2594.
This is the plant mentioned by Welwitsch in Journ. Linn. Soe. iii. p. 151 (1859) as a genus nearly related to Dorstenia and as a large woody shrub 4 ft. high, in general habit like a fig, but with the receptacles obconic truncate and open, just as in Kosaria. Lichen n. 477 grew on the leaves of this shrub at Capopa in the spring and summer of 1855 ; and the fungus n. 508 about its branchlets.
Brunnichia africana Welw. herb. no, 1754 (ante, pp. 905, 906) grew in company with the 7rymatococcus ; also a scarlet-flowered Ochnacea (cf. Ochna membranacea Oliv., var. rubescens ; ante, p. 120), and Com- bretaceze with velvety fruit (cf. Combretum paradoxum Welw. herb. no. 4385, ante, p. 350).
It is, perhaps, the ‘‘ Matomba,” which Welwitsch in his mss. says is the name of a small or middle-sized tree, belonging to this group of plants, and that with it the negroes in the district of Cazengo make very strong cords. In Barra do Dande the name “ Matombe ” is used for Raphia textilis Welw.

In primitive forests, on the lower slopes of the Queta mountains near Canguerasange and around Bango, on a mica-schist formation, with foliage, Oct. 1854 ; Bango road, July 1855; Queta mountains, beginning of Oct. 1855 ; near Sange, N-delle, Mata de Quibange, etc., plentiful, fl. Nov. 1855, fr. Dec. 1855 to Feb. ; on the slopes of Alto Queta, plentiful, male fl. end of Sept. 1856 ; Mata de Quilango near Sange, fr. Dec. 1855. Native name ‘‘ Camba- Camba” or ‘“Mucamba-Camba”; colonial name “ Amoreira” or ‘Moreira.’’ It is milky in all parts after the fashion of the Figs. No. 1559, and Cout. Carp. 897.
This is the tree referred to by Welwitsch, Apontam. p. 546 sub n. 68 (1859), as a new genus allied to Morus. The moss n, 132, Schlotheimia rugifolia Brid. grew on the trunk of ‘‘ Mucamba-Camba ” at Sange in Dec. 1854.

Branchlet of a more adult tree, given to Welwitsch by his friend, Senhor Carvalho, under the name of “Moreira';” at Fazenda do Monte Caffé, without fl. or fr. Dec. 1860. No. 1561.
These determinations are doubtful; I have not seen the type of Engler’s species. Welwitsch thought that No. 1560 might be a young state of the previous species, and Ficalho, /.c., appears to refer to these Nos. and to confirm Welwitsch’s opinion.

GoLunco ALTo.—A tree, 40 to 80 ft. high ; trunk bare of branches below, above terminating in an ovoid head ; timber whitish, straight, strong, very useful, called by the negroes ‘‘ PAo Cababa”’ or ‘“ Quibaba.” In the primitive forests of Sobato Cabanga-Cacalungo ; fr. 3 Feb. 1855, No. 6285. <A tree, 20 to 40 ft. high; trunk 8 in. in diameter at the base or more ; branches slender, as well as the branchlets erect-spreading, dusky-grey, punctate with very small white warts ; leaves rigid, dark- green above, paler beneath, thick but not fleshy, coriaceous or scarcely so; fruit on axillary solitary simple or rather dichotomous peduncles; unripe fruit green, ovoid-compressed or tetragonal-pyramidal, quadri- costate (two of the ribs less prominent than the others), crowned at the apex with two bifid connivent styles or stigmas or with their remains (the stigmatic lobes divaricate) ; young seed pendulous from the top of much larger cavity of the young fruit ; ripe fruit cinnabar- red, drupaceous, juicy, monopyrenous; seed bony, quadricostate, cotyledons plicate ; radicle thick. In hilly bushy places in Sobato Bumba, near Bumba, fr. 2 May 1855; also at the outskirts of forests among the Bango and Queta mountains, fl. and young fr. 12 Nov. 1855. Native name “ Quibaba.” No. 6298. In fl.-bud and young fr. No. 6299. Without fl. or fr. Apparently this species. No. 6300. In fr. Determination doubtful (cf. Rinorea). No. 6711.
CAzENGO.—In the Cacula forests ; fr. June 1855. No. 6284.
The following No. should be compared with this species :—
IstaNnD oF St. THomas.—Called ‘“ Capitao.” Withont fl. or fr. No. 6303. ‘‘Capitao”’ is used for joinery, turning, and building (see Cat. Exposit. Paris 1867, sect. Portug. p. 427 n. 14).
“ Quibiba roxa” or Red Quibaba is a tree 60 to 100 ft. high, which grows in groups constituting the bulk of forests and forms one of the finest ornaments of the virgin forests of Golungo Alto and Cazengo ; its trunk is always straight, and not uncommonly attains a height of 60 ft. and more, nearly cylindrical to the height often of 40 ft., with a diameter from 2 to 2} ft. at the base; the bark is whitish grey, and the wood is nearly but not quite always cherry-red or blood-red in the middle and white towards the outside; the head is rather lax, and the leaves variable in shape and substance. Welwitsch had no oppor- tunity of witnessing any application of it made by the natives ; he regarded it as a new species of Sponia (see Welw. Synopse Explic. p. 12. n. 25 [1862]). It doubtless is this and possibly also the previous species of Celtis. The ‘‘Quibaba”’ of Mussengue or of Hungo is Khaya anthotheca C.DC. ; ante, p. 135. The “ Quibiba” of Queta or “Quibaba quina” is Entandrophragma angolense C.DC. ; ante, p. 136. “ Quibeba”’ is Ficus Quibeba Welw. herb. no. 6399. The Bunda name “Quibaba,” plural ‘‘Ibaba,” signifies in general the bark of any tree whatever, and is used in Golungo Alto for trees of quite distinct families. It was probably on the branchlets of the heads of this tree that the lichen n. 156, Placodium Brebissonii, var. microspora Wain., grew in the Sange forests in April 1856 ; also lichen nn. 203 and 204.

This is apparently the same species as a plant collected by G. Don in St. Thomas’s Island, and mentioned by Planchon and Henriques, Il.cc.; the leaves in Welwitsch’s specimen are, however, rather smaller, about 3 in. long by an inch broad ; the fruit is about $ in. broad, 14 in. long, + in. thick. Don’s plant has been considered by Henriques, l.c., as the same species as Wight’s Indian plant, and therefore Welwitsch’s specimen should probably be referred to the same, as given above, Hook. f. in Fl. Brit. Ind. v. p. 483 (Dec. 1888) suspected that C. philippensis is not distinct from C. Wightic.

In wooded places at Monino by streams, in company with the willow-like Proteacea, Faurea saligna Harv. (Welw. herb. no. 1592); fr. March 1860. It is singular that the leaves on the shoots which bear the female catkins are always more or less obtuse at the apex, while the rest of the leaves on the same branches have a long acumen like those on the male plants. No. 6333.
