xcvii. LABIATE. [Odmum 



XCVII. LABIATiE. 



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 Tinnea furnish from their dried 

 leaves antiscorbutic powders; and the genus ^foesia, when seen 

 without its flowers, much resembles rosemary,
