316 XCII. SCROPHULARIACEE (HEMSLEY AND SKAN). [Stemodiopsis. 
from the description and figure of this species I. have little doubt that Buchanan’s 
specimens belong to the same genus, notwithstanding the presence of a distinct 
palate in the corolla which Engler does not mention at all. The stamens appear to 
be the same except that the longer filameuts in S. Buchanani are merely curved, not 
twisted. 
Buchanan’s 1220 differs from his 365 in several respects. The former has much 
larger almost quite glabrous leaves, longer petioles, flowers often 3 together, longer 
and narrower calyx-segments and longer capsules. This specimen appears as if it 
had grown in wet places and the other in dry stony soil. 
3. S. humilis, Skan. A perennial herb branched from the base, 
the whole plant so far as known less than 14 in. high, densely covered 
with short stiff whitish hairs; branches ascending or spreading, slender, 
$-llin. long. Leaves ovate ; blade 3-4 lin. long, 13-3} lin. broad, 
acute, cuneate at the base, serrate; teeth 3 or 4 each side, rather 
coarse ; petiole 24-3 lin. long, slender, triangular. Flowers solitary ; 
pedicels filiform, 12 lin. long ; bracteoles setaceous, scarcely } lin. long. 
Calyx-segments narrowly linear-triangular, slightly unequal, 14-14 lin. 
long, about } lin. broad at the base, densely covered with rather short 
stiff spreading hairs. Corolla 4 lin. long; tube 2} lin. long, } lin. broad 
at the base, enlarged upwards; upper lip deltoid-ovate, about 14 lin. 
long, 1% lin. broad at the base, shortly 2-lobed, slightly fimbriate ; lower 
lip 1} lin. long and broad, very shortly 3-lobed, shortly pubescent 
inside, Filaments of the longer stamens about 1% lin. long, curved at 
the base, of the shorter about 1 lin. long; staminode filiform, 3 lin. 
long. Style 1? lin. long. Capsule ellipsoid-conical, about 3 lin. long, 
rather abruptly beaked, 2-furrowed, turned downwards, very sparingly 
beset with short stiff hairs. Seeds as in S. Buchanani. 
Mozamb. Dist. British Central Africa: Nyasaland ; near Mount Chiradzulu, 
Cameron, 182 ! : 
Very near S. Buchanani, but it is much more pubescent and the flowers are 
about as large again. The striking difference in the size of the plants of the two 
species is probably accidental. 
22, LIMNOPHILA, R. Br.; Benth. et Hook. f. Gen. PI. ii. 950. 
Calyx 5-partite; segments narrow, imbricate, subequal or the 
posticous larger. Corolla-tube cylindric ; upper outside lip suberect, 
broad, entire or shortly bifid; lower lip spreading, 3-tid, not plicate at 
the base, Stamens 4, didynamous, included ; filaments filiform ; anther- 
cells separate and usually stipitate, more rarely subcontiguous. Style 
deflexed at the apex with two short stigmatose Jamelle. Capsule 
broadly ovate or oblong, usually obtuse, dehiscence septicidal and 
loculicidal ; valves 4. Seeds many, small, striate, reticulate. —Glabrous 
or slightly pubescent herbs, often aromatic and having pellucid dots, 
usually growing in marshy places. Leaves opposite or verticillate, den- 
tate or incised or the submerged leaves divided into capillary segments. 
Flowers axillary, solitary, pedicellate, the upper often forming a termina 
raceme ; bracts small, linear, inserted under the calyx.—Ambulia, Lam.
