tjrrahamstown) and in the West and South- West (not on the Cape Peninsula), 
Lohostemon Lehm. is mostly confined to the South-West, but also found in 
the West and the Karroo (extending to the Uit. and Albany divs.). The 
only native species of Echium L. is found in the Stellenbosch div. 
Verbenaceae. 
Bouchea Cham, is represented in all South African regions. Four (or 
five) genera are endemic in the south-west coast region, of these only 
Stilhe Berg, extends to the Uit. div. The remaining genera have a decided 
eastern and north-eastern distribution. Of these Lijjjna L. extends west- 
wards to C-rahamstown, Priva Adans. to our area, Vitex L. to Komgha, 
Clerodetidron L. to Port Alfred, Avicennia L. to Peddie. Duranta L. (at 
least in the native state) does not come near our area, Lantana L. is absent 
in the West and South-West (except one introduced species). The species of 
Verbena L. found in various parts of South Africa are all introduced. 
Labiatae. 
Genera of more or less general distribution in South Africa : Mentha, L., 
Salvia L., Stachys L., Acrotoma, Benth. (absent from southern coast dis- 
tricts), Leonotis R. Br., and Teucrium L. (absent from the West). Sixteen 
genera have an essentially eastern and north-eastern distribution. Of these 
the following penetrate, mostly in the coast districts, a variable distance 
westwards : Becium Lindl. (to Uit. div.), Ocimum L. (to Komgha), Ortho- 
sijjhon Benth. (to the Pirie bush or even to Albany [?] ), Sijncolostemon E. 
Mey. (to East London), Plectranthu>^ L'Herit. (to Caledon), Coleus Lour, 
(to the Peddie div.). Aeolanthtis Mart, (to G-raaff Reinet), Jffcromerm Benth. 
(to Queenstown), Leiicas Burm. (to the Uit. div.), Lasiocorys Benth. (to 
the Uit. and Jansenville divs.), Ajuga L. (to the Uit. and Somerset East 
divs.). Two genera are only found in the north-eastern parts, Ballota, L. in 
the western, south-western, and central parts (to Queenstown). Ceclro- 
nella Moench. (South-west) and Marrublum, L. (Table Mt. and Addo) are 
introduced. 
Solanaceae. 
Solanum L., Wifhania, Pauq., and Lyciuni L. are found in all South 
African regions, the last especially in the drier parts, Physalis L. (with the 
exception of one Natal species?), Nicaiidr a Ada,i\s., Datura L., Nicotiana L., 
and Cestrum L., are introduced, but have become naturalised in numerous 
places. (For BetziaThnnh., see under Loganiaceae.) 
Scrophulariaceae. 
Twenty-one genera have a very wide distribution in South Africa. 
Of these only Teedia Burch. and Bellardia All. are not recorded from 
the Uit. and P. E. divs., Mimulus L. and Striga Lour, (common in th
