Throughout India on the plains. — Distbib. Afghanistan. Persia. Australia. 



Glabrous, very erect, 6-24 in. ; branches numerous, sharply quadrangular. Cauline 

 leaves 1-1^ in. Bracteoles on the cjme-branches most minute, linear, Calj/x cam- 

 panulate, hemispheric or scarcely elongate ; teeth 4, short-triangular. Petals 0, or 

 small and caducous. Stamens 4, 6 or 8. Capsule often ultimately red, globose, not 

 enclosed by the calyx. Seeds half-ellipsoid, excavated on the plane face. — Very 

 closely allied to A. senegalensis and united with it by Mr. Hiem, perhaps correctly, 

 but the two forms do not meet or pass into each other in India. Cryptotheca dicho- 

 toma, Blume Bijd. 1128 ; DC. Prodr. iii. 76 (Ammannia microcarpa, DC. Prodr. iii. 

 77), from Java and Timor, has been united with A. multiflora Boxb. by Kurz in 

 Jowm. As, Soc. 1871i pt. ii. 56, but differs in the much more elongate calyx-tube and 

 larger cauline leaves : it is certainly very near A. multiflora.

 Bubaviriculate at the base, cymes very shortly pedimcled 3-5-flowered, calyx in

Erect, 6-18 in., branches quadrangular, often scabrous. Cauline leaves 1-2 in., 

 sometimes very narrow. Calyx in fruit J in,, often minutely pubescent or scabrid, 

 nearly truncate ; teeth 4, small. Petals -^ in., obovate, rose-coloured. Stamens 8, 

 filaments long, dark-red. Capsule somewhat ellipsoid, as long as the calyx. Seeds 

 subhemispheric. — This species is reduced to A. latifoUa Linn, by Griseb. Fl. Brit. 

 West Indies 270 ; but the "West Indian specimens, though like the Indian in leaves 

 tad habit, are entirely without the subalate angles of the ripe fruit which form the 

 essential character of A. octandra. 



18. A. subrotunda, Wall, ex Kurz in Journ. As. Soc. 1871, pt. ii. 65; 

 " leaves sessile almost orbicular pinnate-nerved, flowers on slender short pedi- 

 cels forming shorter or longer slender racemes."

2. KyDB.Oi:.YTKXtVnX, J3bo^./. 



A glabrous aquatic herb. Lower leaves whorled, linear. SpiTtes exsert out 

 of the water with oblong bractii'orm leaves. Flowers whorled, subsessile in the 

 axils of bracts, lower whorls distant, upper approximate, often with opposite 

 bracts ; bracteoles 2, subulate. Cdyx campanulate ; teeth 4, triangular ; ac- 

 cessory teeth 0. Petds 4, inserted between the calyx-lobes. Starnem 4, on the 

 middle of the calyx-tube. Hypogynous scales 4, bifid. Ovary in the bottom of 

 the calyx, free, 2-ceUed ; style simple, stigma capitate ; ovules not many, pla- 

 centas axile. Capsule small, globose, 2-celled. Seeds 3 or 4 in each cell, ovoid, 

 concave.— A genus only separable from Ammannia hj habif: for hypogynous 

 glands exist in Amm. rotvmdifolia.
