0?i a neto Genus of Scrophularinecc. 



[Oct. 



placenta?, which are large and fleshy, and bear ovula on every part of 

 their surfaces, not meeting in the centre. To this plant, which has not 

 the usual habit of Hcrpestes, w e gave the MSS. name of Cardiolophus 

 decussates ; but I am not sure whether the above structure of the 

 ovarium is of generic importance. Its occurrence, however, although 

 in this perhaps solitary instance, weakens the distinction between this 

 order and Cyrthandracece. 



The characters of Microcarpcsa and Peplidium, as given by Mr. 

 Bentham, seem to me to admit some doubt. In one species in my 

 possession, certainly referable to Microcarpcsa as characterized in Mr. 

 Brown's Prodromus, but which, as I have not seen ripe fruit, I am 

 unable to refer positively either to the same genus or to Peplidium of 

 the Synopsis, the developed stamina correspond to the lower pair of 

 the didyn anions genera of the order, and in addition the anthers are 

 unilocular. 



The abortion of the lower pair of stamina of Bonnaya appears to be 

 constant ; and it is by this at once distinguished from Vandeliia. This 

 latter genus passes into Torenia ; one species, which I refer to Vandel- 

 iia pedunculata (Scroph. Ind. p. 37) having the corolla of the former, 

 wanting the fornicate upper lip, which appears to me to characterize 

 the true species of the latter. The only constant distinctive character 

 of Torenia, at least as regards Vandeliia, consists in the plicate calyx ; 

 and, as regards Mimulus and Uvedalia, in the dehiscence of the capsule, 

 and perhaps the structure of the seeds. I am acquainted with one 

 species, which agrees in every other respect with Torenia, but the 

 lower pair of filaments are entirely simple. This I propose to cha- 

 racterize thus : 



Torenia edentuld — mihi, erectiuscula molliter hirsuta, foliis petio- 

 latis cordato-ovatis rugosulis floribus pseudo-axillaribus fasciculatis 

 racemosisque, filamentis longioribus basi edentulis. 



Hab. Circa Suddiya, regionis Assamicae Superioris. 



Corolla calyce vix duplo longior, saepius cssruleo pallide tincta, lobis 

 lateralibus labii inferioris partim saturate azureis, medio macula lutea 

 notato. 



The flowers of both Vandeliia and Torenia are described by Mr. 

 Bentham as axillary ; the infloresence is, however, in both terminal, 

 especially of those species which have fasciculate flowers. It appears 

 axillary only, when one of the axils alone of the two terminal leaves, 

 gives origin to a branch, which, as in many other instances, has the 

 appearance of being the true continuation of the axis. 



I am inclined to think that good additional distinctive marks may be 

 drawn from the seeds. Synphillium, Bonnaya, Vandeliia and Torenia 

 agree in having foveolate seeds ; these foveoli vary in number in the 

 different species ; they are least numerous and nearly definite in Syn- 

 phyllium ; much more numerous in the' species of the three other
