316 xcn. scrophulariace/e (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 filaments in 8. 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 1 \ in. high, densely covered 

 with short stiff whitish hairs ; branches ascending or spreading, slender, 

 \-\\ in. long. Leaves ovate ; blade 3-4 lin. long, lf-3^ lin. broad;, 

 acute, cuneate at the base, serrate ; teeth 3 or 4 each side, rather 

 coarse ; petiole 2|— 3 lin. long, slender, triangular. Flowers solitary ; 

 pedicels filiform, 1-| lin. long ; bracteoles setaceous, scarcely f- lin. long. 

 Calyx-segments narrowly linear-triangular, slightly unequal, 1^-lf 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 1^ 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. Fdaments of the longer stamens about \\ lin. long, curved at 

 the base, of the shorter about 1 lin. long; staminode filiform, \ lin. 

 long. Style If 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.

 Cameron, 182 ! 



Very near $. 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-ficl, not plicate at 

 the ba»e. Stamens 4, didynamous, included ; filaments filiform ; anther- 

 cells separate and usually stipitate, more rarely subcontiguous. Style 

 deflexed at the apex with two short stigmatose lamellae. 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 terminal 

 raceme ; bracts small, linear, inserted under the calyx. — Ambidia, Lam.
