Bengal : Rajmahal Hills south of Salnbganj, common among the ridges on 

 the loamy moist paths, alt. ca. -500', Oct. 1870 (S. Kurz ! ). 



7. A minute terrestrial prostrate plant, growing in tuf ts 1 cm. in diame- 

 ter, with very few flowers (generally the species flowers abundantly). 

 Calyx o-merous. 



K. Bot. Garden, Calcutta, Aug. 1857 (S. Kurz. !). 



8. A large form, reaching 10 cm. in height, with very long weak fleshy 

 stems, densely interlaced and rooting at the nodes, evidently trailing in 

 very shallow water. The trailing stems are leafless. Leaves on the erect 

 parts reaching 5 mm., about as long as the internodes, decussate, rarely 

 ternate. A few smaller oval leaves below. Flowers minute. Calyx-teeth 4. 



N.Bengal: between Titalya and Silligoree, dried-up pools, Oct. 1868 

 (S. Kurz !). 



9. Caespitose, growing in tufts 2-3 cm. in diameter. Leaves 2-3-nate. 

 Calyx-teeth 4, longer than tube. A few L'-valred capsules observed. 



N. Kanara : on garden-walks at Kadra, Oct. 1885 (Talbot, No. 1317 !). 



10. Similar to the last, but with weaker trailing stems. 

 Khasia Hills, alt. 2,000' (J. D. Hooker and Thoms. !). 



11. Very similar in habit to form 4, but the stems are much more 

 numerous, stouter, and with contracted internodes, subsimple. Calyx-teeth 

 3-5, deltoid-acute, shorter than the tube. Capsules certainly 3-valved, 

 which seems to have escaped Clarke's notice (see his remark in Hook, f . 

 Fl. Brit. Ind. 1. c). 



Chota Nagpur : Parasnath, alt. 1,000-4400' (Clarke, No. 33811 !). 



12. A very densely tufted plant with erect stems, apparently growing on 

 soft mud. Leaves reaching 3 mm. as long as the internodes. Calyx elongated, 

 quadrangular, reddish, teeth 4-5, deltoid-acute, almost as long as the tube. 

 At the bottom of the calyx-tube a few minute hypogynous scales. Bracteo- 

 les shorter than calyx. 



Sikkim: Labhath, alt. 8,000' (Ribu and Rhomoo, No. 2637!). Similar 

 specimens from Upper Chindwin, Burma, collected by Meebold, Dec. 1907, 

 Nos. 7569 ! 7808 ! 



13. A small difl'use herb, lying flat on the ground in damp places. Stems 

 reaching 7 cm, generally shorter, stout, fleshy, quadrangular, slightly 2- 

 vvinged. Leaves opposite, reaching 3 mm, sparsely hairy on the upper side 

 when old. Bracteoles as long as the calyx-tube. Calyx-teeth 4-5, greenish- 

 white and fleshy when young, brown when old. Stamens 2 or 3 ; anthers 

 brown. Stigma 3-lobed, green when young, brown when old. Capsule almost 

 spherical, flattened on top, tubercled all over, largest tubercles on the sut- 

 ures of the capsule. Seeds many, black, irregularly half-ellipsoidal, excava- 

 ted on the flat side, shining. 



Mt. Abu in Rajputana, Oct. 1916 (Blatt. and Hall. Nos. 3275! 3276!). 



14. Stem submerged, quadrangular, weak, spongy. Leaves mostly 3-4 

 nate, sometimes opposite on the branches, reaching 7 mm. Calyx verv 

 small, teeth 4. The capsule has the appearance of a mulberry on account 

 of the pressure of the seeds from within, pale green, translucent. Seeds 

 twice as along as broad, trigonous with one curved and two plane surfaces, 

 and with a minute beak at one end. 



Mt. Abu: Salgaon Tank (Blatt. and Hall. Nos. 3280 ! 3281 !). 



15. Much like the last, but with 3-5-nate leaves, reaching 11 mm., narrow- 

 er and more acute. 



Bundclkund (Vicary !). 



We have referred the last two specimens to this species although their 

 habit is difl'erent from that of the other Indian specimens. Perhaps they 

 come nearest to No. 17 below. The only alternative would have been 

 to put them under Rutala rfvtiUnris, L. But we have not observed
