After long consideration it has seemed best to group L. nigrescens, Zenkeri, 
Laurentii, Descampsii, unguiformis and elongatus under L. Braunii. The differen- 
tial characters on which the species were founded do not appear to be constantly 
correlated, and some of them seem to represent merely different stages of develop- 
ment. ‘This is especially the case with characters derived from the flower-bud. The 
shape of the basal swelling of the corolla does not appear to be very constant in 
species of Loranthus: typical L. Braunii has usually a globose swelling, but Mon- 
teiro’s specimen from Banana Creek has an ellipsoid swelling, though agreeing in 
other respects with the type. 
59, L. mweroensis, Baker in Kew Bulletin, 1895, 292. Branch- 
lets terete, slightly costate, greenish, glabrous, finely lenticellate ; 
‘branches wrinkled, coarsely lenticellate; internodes }-3 in. long. 
Leaves ternate, lanceolate, apex not known, base obtuse, 31-44 in. long, 
1}-2 in. broad coriaceous, glabrous, dull; lateral nerves patulous- 
ascending, 4-5 on each side, slightly raised especially on the lower 
surface ; petiole 6-7 lin. long, channelled. Umbels fascicled on the old 
wood, 6—7-flowered; peduncle 4-44 lin. long; pedicels 1 lin. long; 
bract subequal to the calyx and receptacle, obliquely ovate-saucer- 
shaped, ciliate, dorsal margin 3 lin. long, ascending, umbonate on the 
lower half, ventral and lateral margins } lin. long, spreading. Recep- 
tacle and calyx together suburceolate, #-% lin. long. Calyx sparingly 
denticulate, }-3 lin. long. Corolla 14 in. long, apical swelling of the 
‘bud cushion-shaped, 5-ribbed, basal swelling ellipsoid, 14 lin. long; 
‘tube glandular within; lobes elongate-spathulate. Anthers cuneate, 
emarginate, 1} lin. long, cells diverging upwards. Disc } lin. high, 
ifleshy. Stigma peltate, ? lin. in diam. 
Mozamb. Distr. Rhodesia: Moero Plateau, Carson, 27! Salisbury, om 
Protea sp., Rand, 532! 
Rand’s specimen differs from the type in the leaves, which are elliptic-oblong, 
rounded or obtuse at the apex, 2-3 in. long, 1-1} in. broad. It may possibly represent 
a distinct species. 
60. L. anguliflorus, Hngl. in Engl. Jahrb. xx. 107. A_ big 
radiately-branched shrub. Young branchlets slender, glabrous, dark, 
adult ones rather stout, wrinkled, yellowish-brown, 8 lin. in diam. 1 ft. 
below the apex; internodes 4-13 in. long. Leaves opposite, elliptic, 
broadly ovate or suborbicular, apex rounded, base obtuse, 14-2} in. 
long, 1-2 in. broad, chartaceous or thinly coriaceous, glabrous, about 
7-nerved at or shortly above the base; nerves slightly raised on both 
surfaces; petiole 5-10 lin. long. Umbels axillary, fascicled, 3—-6-
