ad (3). Near (1), but with longer internodes and larger leaves; there 



is a tendency towards the formation of panicles, and the pedicels 



are short. 

 ad (4). Like (1), but with short pedicels. 

 ad (5). A luxuriant robust specimen with many stems from the root 



less conspicuous petals and shorter pedicels than (1). 

 ad (6) A specimen more like (2), with longer leaf-Jike bracts and fewer 



flowers, 

 ad (7). Very similar to the two extremes on WallicL'sshee j. 

 ad (8). Very close to the intermediary specimen on VV^allich's sheet 



erect, 

 ad (9). The only specimens obtained outside Burma, Thej^ come close 



to (8), bat are smaller. 



Formaf. inncvnndra. — Stem ascending, rooting at the lower nodes, 

 branched, subqnadrangular. Leaves broadly obovate, upto 15x6 mm., 

 rounded at the apex. Flowers in axillary, sometimes branched spikes, 

 which are longer than the leaf, cylindrical, dense. Bracts as long as the 

 flower, elliptic, subacute. Bracteoles 2, only half as long as the calyx-tube. 

 Calyx-tube with the usual 8 very line lines, narrow ; teeth less than half 

 the length of the tube, deltoid-acuminate. Petals red, obovate, as long as 

 the calyx-teetl) Stamens inserted near base of tube, far exserted. Stj'le

(1) S. Kurz C" On some new or imperfectly known Indian plants " in Jour. 

 As. Soc, Ben^., XL, II (1871) .^)5) grives the following: description of a plant which 

 he calls Ammannia subrotunda. Wall : " Leaves sessile, almost orbicular, penni- 

 nerved ; flowers on slenvier s^hort, pfidicels, forminjr shorter or lorser slender 

 racemes. "^Clarke (Hook. f. Fl. Brit. hid. ii (:879j 5(591 copies Kurz's description, 

 retaining the name, and adds, that he has not seen the plant. He does not give 

 the other reference to Kurz \ " Contributions towaids a knowledge of the Burmese 

 Flora" in Jour. A.. S. Beng., xlvi, ii 1877) 84), in which Kurz gives an almost 

 identical description of the plant, ad' ing however : " Wall. Cat. 20!tC>. Hab. Ava. 

 from Segain and Mandalay northwards in the Irrawady valley. — Fl. Fr. Jan." — 

 We find in Herb. Calc a sheet bearing the label " 2()i)(> Ammannia subrotunda, 

 Wall." in Wallich's own handwriting. Below is the following rote by G. Watt, 

 dated 1882 : '' T can see no diflference between the abovp, and they should, in my 

 opinion, be regarded as in Fl. Brit. Ind.as forming a variety at most of the common 

 A. peploides. Since the name A- subrotunda is not published by AVallich, I presume 

 that the above label is Kurz's authority for that name." A.s a matter of fact, Clarke 

 gives ''A. latifolia\ Wall. Cat. 20'J(), partly, under A. peploides, Spreng. The 

 same reference, however, occurs also under A. rotundi folia.. Hj,m. in Fl. Brit. Ind. 



Now ' latifolia' is written in pencil above' SHtro^w^ifZa', probably by Wallich 

 himself. There is another label on the sheet in question, also in Wallich's hand, 

 which seems to be the original one, since the locality and date are given. It bears 

 the name ' A. rotundifolia. Buch.' 



The history of the name ' A. subrotunda. Wall.' is probably this : Wallich first 

 thought the plant was A. rotundifolia, later, that it was a new species and wrote? 

 on one of the sheets bearing the number 20'.)(i the name A. subrotunda For some 

 reason or other he foiuid the name unsuitable and changed it into A- latifoli" 

 writing down the name on all the sheets. The first sheet was the one in Herb. 

 Calc. seen by Kurz who retained the name A. suirotunda.. Wall. The other sheets 

 wei'e studied by Clarke who put them under ^1. fcpl. and A. rotundifolia, respect- 

 ively. This is the reason why Clarke does not mention Wall. Cat JODti as referring 

 to A. subrotunda. He must, however, have seen Kurz's second note, since he gives 

 Ava as localitv.
