near, agreeing entirely in placentation, direction of the ovula and 

 situation of the foramen. 



The second is of more importance. In speaking of the distinction 

 between Primulacece and certain genera of Scrophularinece, Mr. Ben- 

 tham remarks, in reference to the stamina of the two orders belonging 

 to different series, that in Scrophularinece no trace of the inner series, 

 that which is alone developed in Primulacece, has as yet been observed, 

 unless " the deeply cleft disk, described by Martius as encircling the 

 ovarium in Herpestes lanigera, or the scales in the tube of the corolla 

 of Artanema be considered as abortive stamina." Without having any 

 knowledge of Herpestes lanigera or Artanema, there can I think be 

 no doubt that the disk of the former is merely a development in ex- 

 cess of the glandular disk, so common and nearly universal in the 

 order, and which, according to its completion or incompletion, I take 

 to represent the whole or part of the inner series of stamina. This 

 disk frequently presents traces of division; the divisions, although 

 obscure, then corresponding to, or being opposed to, the component 

 parts of the corolla. When incomplete, the deficiency, so far as I 

 know at present, appears always to take place posticously. Hence, as 

 in most diandrous genera of this order, the upper stamina are alone 

 developed, the direction of the development of the two series appears 

 to be, as indeed might be expected, reversed. The remainder of my 

 observations will be confined to the tribe Gratiolece of the same Sy- 

 nopsis. 



Of the genus Mimulus Upper Assam affords one species, which ap- 

 pears to be new, and which may be thus characterized : — 



Mimulus Ass amicus, Mihi: diffusus subglaber, foliis obovatis vel ovatis 

 basu versus integris cseterum argute dentalis penniveniis superioribus 

 sessilibus, calycibus campanulato-tubulosis truncatis dentibus brevibus 

 subequalibus, fructiferis amplis subinflatis. 



Hab. Ad ripas arenosas fluminis Burrumpootur, regionis Assamicae 

 Superioris. 



Herba pusilla basi radicans. Folia inferiora obovata, reliqua ovata 

 et basi attenuata, vel obovato-lanceolata, dentibus mucronatis. Flores 

 oppositi, parvi, lutei, tubo intus rubro guttato. Pedicelli filiformes 

 demum folia excedentes. Anther cb basi celluloso-papillosae. Glandula 

 hypogyna nulla. Placentae stipitatse. Semina pallide brunnescentia, 

 oblonga, ssepius pilis brevibus hyalinis apice 2— 4— uncinatis hispida.

Of the genus Herpestes, one curious species was found by Dr. Wal- 

 lich and myself at Jumalpore, singular in the great development of 

 the calyx and in the unilocularity of the ovarium, depending upon the
