After long consideration it has seemed best to group L. nigrescens, Zenkeri, 

 Laurentii, Descampsli, iinguiformis and elongatus under L. Bramiii. The differen- 

 tial characters on wl)ich the species were founded do not :»ppear to be constantly 

 correlated, and some of them seem to represent merely different stages of develop- 

 ment. This is especially the case with ciiaracters derived from the tlower-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. 



50. L. mweroensis. Baker in Kew Bulletin, 1895, 292. Branch- 

 lets terete, slightly costate, greenish, glabrous, finely lenticellate ; 

 branches wrinkled, coarsely lenticellate ; internodes f-3 in. long. 

 Leaves ternate, lanceolate, apex not known, base obtuse, 3J-4J in. long, 

 ]J-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, 0-7-flowered ; peduncle 4-4 J lin. long; pedicels 1 lin. long; 

 bract subequal to the calyx and receptacle, obliquely ovate-saucer- 

 shaped, ciliate, dorsal margin J lin. long, ascending, umbonate on the 

 lower half, ventral and lateral margins \ lin. long, spreading. Recep- 

 tacle and calyx together suburceolate, |-J lin. long. Calyx sparingly 

 denticulate, |-| lin. long. Corolla IJ in. long, apical swelling of the 

 "bud cushion-shaped, 5-ribbed, basal swelling ellipsoid, Ij lin. long; 

 tube glandular within ; lobes elongate-spathulate. Anthers cuneate, 

 emarginate, IJ lin. long, cells diverging upwards. Disc J lin. high, 

 fleshy. Stigma peltate, \ lin. in diam.

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^ i". broad. It may possibly represent 

 a distinct species. 



60. L. anguliflorusy Engl, in Engl. Jahrb. xx. 107. A big 

 Tadiately-branched shrub. Young branchlets slender, glabrous, dark, 

 adult ones rather stout, wrinkled, yellowish-brown, 3 lin. in diam. 1 ft. 

 below the apex ; internodes |— If in. long. Leaves opposite, elliptic, 

 broadly ovate or suborbicular, apex rounded, base obtuse, 1J-2J 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-
