depressions which run down for some distance along the tube ; correspond- 

 ing with those depressions there are rounded ridges on the inner side with 

 about 6 yellow transverse bands which are also visible from outside ; in the 

 lower part the ridges are minutely pubescent and have a number of long 

 clavate scattered hairs. Stamens didynamous ; filaments glabrous, in- 

 serted in the tube at about equal height, arched ; anthers touching in 

 pairs; longer filaments bent at the place uhere they leave the tube; 

 anther-cells small, equal, muticous, diverging, distinct; pollen ellipsoidal 

 white; shorter pair of stamens included, longer exserted. Style 6mm. 

 filiform, glabrous ; stigma large, bilamellate, one lobe larger, recurved, lobes 

 oblong, papillose on their inner surface. Ovary o\oid, slightly compressed, 

 glabrous. Capsule included in the calyx, loculicidally bivalved, com- 

 pressed, obtuse. Seeds numerous, angular, slightly falcate, brown. 



Locahty : Victoria Gardens, Bombay, March 1917 (Nos. 1718, 1719,1766), 

 flowers throughout the year ; Igatpuri, September 1917, collected by Mr. 

 C. McCann (Nos. 1720, 1721, 17:^2). 



Stemless with radical leaves in the dry season, with elongated stem 

 during the rains. 



There is some probability that this plant is identical with Wight's Mazus 

 surculosus (Ic. IV, iii, p. 1, t. 1407). Wight says that the drawing was 

 sent to him by Edgeworth from Mussoorie. Now the calyx in Wight's 

 figure comes very near that of our plant, but Wight says that the lobes 

 are shorter than the tube. Hooker f. (Kl. Brit. Ind. iV, 260) puts Wight's 

 plant under M. suickIosks, Don, but with a sign of interrogation (the figure 

 is wrongly cited as t 1467) and adds that " the figure in Wight's Icones 

 represents the calyx very incorrectly." As a matter of fact, Al. surculosus,. 

 Don, should have the calyx-lobes ^ the length of the tube. That Wight's 

 drawing does not belong there is evident, and we have better reasons to 

 include it under the new species, although we refrain from doing so for the 

 present. It is not impossible that the slight diflerences will be found to 

 be due to climatological factors. 



Mazvs rvgosus, Lour.- — I>alzell and Gibson (Bombay flora, 176) mention 

 this plant as occurring in Thana, Salsette : "On garden-walks in the rains. '" 

 Cooke (H. B. Pros. II. 310) excludes this species from the Bombay Presi- 

 denc\ , on the ground that neither he himself nor any of the I'oona plant- 

 collectors have found it in Thana, although they have often searched for 

 it. He mentions, however, that there is a sheet of DalzeD's in Herb. Kew 

 with the note : " Found in a garden, but I do not think mdigei ous." It 

 seems probable that, although no locality is given on the sheet m question, 

 this was the identical | lant referred by D. & G. 



It appears that the distribution of the genus Mazvs offers many points 

 of interest. We should be much obliged for any communications regarding 

 the occurrence of the species of Mazus. 



LINDENBERGIA, Lehm. 



Lindenhergia pnlyantha, Eoyle, should be reduced to L. urticccfolia, Lehm. 



There are apiarently many doubtful points in the genus Linden bergiu 

 which, in the course of time, must be cleared up. We are making an 

 attempt with regiird to the two sptcies mentioned above. 



Bentham (in DO. Prodr. X, 876) makes two subdivisions of the genus, 

 one comprising the species with a hard, perennial or woody stem, the other 

 with slender annual stems. In the latter division he places L. uiticcsrolia 

 and L. polyantlia. These subdivisions cannot be maintained. We have 

 numerous specimens of L. urtiecefolia which are woody below and in all 

 probability perennial.
