Of the former, B. pseudoverticillata, Mart. & Gral., is a not un- 

 common state of B. sessilijlora, H. B. K. ; B. obtusifolia is identical 

 with B. microphylla, H. B. K. ; the third, B. elliptica, is unknown 

 to me. The ten published by Kunth appear to be chiefly slight 

 varieties of some of the common Mexican species, but, for want of 

 a critical comparison with wild specimens of these very variable 

 plants, it is impossible to form any plausible opinion respecting 

 them, and they must remain as so many puzzles until authentic 

 specimens shall have been examined by some one well acquainted 

 with the genus in general. 



On the other hand, two Madagascar plants retained as Budd- 

 leias in the ' Prodromus,' B. diversifolia of Vahl and my own B. 

 rondeleticeflora, must be removed, as forming Tenore's genus Nico- 

 demia. With precisely the flowers and ovary of Buddleia they 

 bear, instead of a capsule, an indehiscent berry, not perhaps so 

 fleshy as in most of the Fagraeece, but white, and filled with a 

 juicy pulp in which the seeds are immersed. This increases much 

 the difliculties of classification ; for by adhering to the tribual cha- 

 racters, these plants must be classed amongst Fagrceece, although 

 in everything but the fruit they are so perfectly Buddleias, that 

 it seems very unnatural to remove them so far from that genus. 

 Many such unnatural separations are, however, absolutely unavoid- 

 able in all classifications of Bubiacea hitherto proposed. 



In Griffith's posthumous ' Icones,' t. 422, the Teucrium macro- 

 stachytm, Wall., is figured as a Buddleia, a name probably pro- 

 visionally given to the plant without examination in the hurry of 

 a mountain excursion, and never intended to be retained. The 

 unrevised publication of all these fugitive memoranda is much to 

 be regretted, as tending to do irreparable and most undeserved 

 injury to the reputation of so eminent a botanist, with those who 

 are unacquainted with the circumstances of the case. 



14. GrENIO STOMA, Forst. 



This genus has the stipules and habit of some JRubiacea, but 

 the ovary is superior, although attached by a very broad fleshy 

 base. The corolla has the contorted aestivation of the Apocynew, 

 and the fruit is not so unlike as has been generally supposed. 

 The two thick concave valves cohering at the base and curved 

 outwards, each crowned by one of the styles, which, though also 

 long cohering, ultimately separate, are very much like two folli- 

 cles. The placentae generally form one central column, but in 

 some species they separate and turn back with the valves. Genio-
