184 FLORA OF PORTUGUESE EAST AFRICA. [Szss. uxx. 
Labiata2.—Ocimum basilicum, common weed on the open 
waste lands. Ocimum suave, common on the coast. Mos- 
chosma riparium, shrubby perennial, found in the dry zone: 
Pycnostachys reticulata, perennial herb. Plectranthus petiol- 
aris and P. tomentosus are the only two forms I have seen 
near the coast, both dwart shrubs. Syncolostemon ramulosum, 
a perennial herb, the only species I have observed. AHyptis 
pecinata, common annual. Mentha aquutica, not very 
common. Stachys wthiopica, herbaceous perennial found in 
certain localities. Leonotis Leonurus, rather a striking 
perennial herb found in open land; rough, strong fibre is 
got from the stems. Leonotis nepetefolia, much of the habit 
of the preceding species. 
AMARANTHACEZ.—Celosia trigyna, common weed, <Amar- 
anthus spinosus, very abundant. Sericocoma chrysurus, 
common. Cyathula globulifera, Pupalia atropurpurea, Airva 
lanata, Achryanthes aspera, Alternanthera sessilis, Gomphrena 
globosa, all common weeds. 
CHENOPODIACEZ.—Chenopodium murale, abundant. Sali- 
corn, herbacea, common. 
POLYGONACEZ. — Oxygonum Dregeanum, very common, 
Polygonum lanigerum and P. tomentosum, both very common. 
LAURINEZ. — Cryptocarya acuminata, a not uncommon 
evergreen tree. 
LoRANTHACEZ.—Loranthus Dregei and L. Kraussianus 
are both very abundant parasitical plants. #Vuseum 
continuum and V. obovatum, very common. The colours of 
the flowers of these parasitical plants, I have always observed, 
are much brighter near the sea than in the interior. 
EUPHORBIACE4.—This is a genus of exceedingly interesting 
plants. Many species found in the dry zone. Euphorbia 
puulijera, E. indica, E. grandidens, E. Tirvealli, and £. 
cervicornis, all to be found. Synadentwm arborescens, abundant. 
Brideia micrantha, very common. Phyllanthus glaucophyllus, 
common shrub, Antidesma venosum, common. Jatropa 
hirsuta and J. gossypifolia are both to be found. Jatropa 
Curcas, physic nut, has been introduced from India. It is a 
valuable fence plant, and about one of the best to grow vanilla 
upon. Croton sylvaticus, abundant shrub. Acalypha petiolaris, 
found in a few places. Ricinus communis, naturalised, but 
not cultivated by the natives; in fact, castor oil is little used
