Syncolostemon. | LABIATA (Brown). 263 
I can find no specific difference between the three above forms, which may 
possibly be only sexual conditions. Guerke did not even distinguish var. Coopert 
from the type. 
2. 8. argenteus (N. E. Br.) ; in height, habit, inflorescence, size 
and shape of flowers exactly as in S. lJanceolatus, differing as 
follows :—stem much concealed by the numerous short axillary 
densely leafy shoots ; leaves $—} lin. long, 1-5 lin. broad, linear- 
lanceolate to broadly elliptic, acute to very obtuse, silvery-white on - 
both sides from dense adpressed pubescence of silky hairs ; branches 
of the panicle rather densely white-pubescent, with tufts of longer 
hairs at the nodes ; pedicels }—3} lin. long ; calyx-tube 14-2 lin. long, 
rather densely pubescent ; teeth } lin. long, narrowly deltoid, densely 
white-woolly on the margins and inner surface ; corolla white.

This may be only a variety of S. lanceolatus, Guerke, as there seems to be no 
evident distinction in its flowers, but the more densely leafy stem and silvery 
leaves give it such a different appearance that I hesitate to unite them. 
3. S. parviflorus (E. Meyer, Comm, 231) ; stems several from a 
woody rootstock, about 15 in. high, obtusely 4-angled, softly pubes- 
cent with slightly spreading hairs ; leaves of the main stems with 
very short leafy shoots in their axils; petiole 4-1 lin. long ; blades 
3-6 lin. long, 13-3 lin. broad, those on the axillary shoots smaller, 
lanceolate-oblong or somewhat obovate-oblong or the lower elliptic, 
obtuse, somewhat cuneate at the base, slightly toothed in the upper 
half or entire, softly pubescent and densely gland-dotted on both 
sides ; inflorescence terminal, 1-3 in. long, simple or slightly 
branched ; whorls 4—6 lin. apart, 2-flowered ; bracts very caducous, 
14 lin. long, ovate, acute, concave, pubescent ; pedicels }—} lin. 
long, pubescent ; calyx pubescent and densely gland-dotted outside, 
glabrous inside the tube, ciliate and pubescent on the inside of the 
teeth ; tube 2 lin. long, campanulate ; teeth subequal, erect, almost 
1 lin. long, subulate from a broad base or the upper tooth shorter 
than the rest and oblong, obtuse ; corolla exserted, about twice as 
long as the calyx ; tube straight, 3}-3} lin. long, gradually enlarg- 
ing upwards, compressed, pubescent outside on the upper 3, and 
inside at about the middle ; upper lip 24 lin. long, erect, 3-lobed, 
pubescent and gland-dotted on the back of the lobes ; terminal lobe 
1 lin. long and almost as broad, oblong, notched at the obtuse apex, 
ciliate with rather long hairs ; lateral lobes } lin. long, very broadly 
rounded, ciliate; lower lip about 13 lin. long, deeply concave, 
obtuse, slightly pubescent and gland-dotted outside ; stamens much 
exserted, subequal ; upper pair inserted about 2 lin. above the base 
of the corolla, 4 lin. long, their filaments free, flattened, with a few 
minute hairs on the face of the basal part; lower pair inserted 
at the base of the lower lip, 3 lin. long, their filaments united to 
the apex, glabrous. Dietr. Syn, Pl. iii, 385; Benth. in DC. Prodr,
