Past I. POLYPETAL^E. 



Thalamiflor^:. 



In December we received at Kew a box, which, owing to the un- 

 settled state of political affairs, had taken nearly a year in transit, 

 containing the botanical results of the explorations during 1882 

 of our energetic correspondent, the Rev. Eichard Baron, F.L.S. , 

 in Central Madagascar. In the present paper I have described 

 the principal polypetalous Dicotyledons which it contains which 

 appear to be new, and of which the material is complete enough ; 

 and I hope next Session to deal with the remaining part of the 

 collection. 



Clematis laxiflora, n. sp. 



Volubilis, obscure pubescens, foliis longe petiolatis deltoideis pinnatim 

 trifoliolatis, foliolis ovatis acutis obscure cuspidato-dentatis membranaceis 

 utrinque viridibus glabris, floribus laxe paniculatis pedicellis elongatis, 

 alabastris globosis, sepalis oblongis sordide purpurascentibus tomentosis, 

 tilamentis deorsum pilosis, stylis dense albo-plumosis. 



A w r oody climber, with slender terete obscurely pubescent 

 branches. Fully-developed leaves deltoid, trifoliolate, with a 

 petiole 2-2£ in. long ; leaflets ovate, membranous, glabrous, 

 2-2| in. long, with a few shallow teeth with minute cusps ; 

 petiolules often bent, the end one nearly an inch long. Panicles 

 deltoid, peduncled, as long as the fully-developed leaves ; pedi- 

 cels slender, the end one 1-1 1 in. long. Sepals oblong, dull lilac, 

 3 in. long. Anthers oblong, | line long, a quarter the length of 

 the filament. Styles densely plumose. — Baron 2448 ! Leaves 

 like those of C mauritiana, but flowers much smaller and more 

 numerous. Of the suberect section I am afraid that C. trifida, 

 Hook. Ic. t. 72, and C. oligophylla, Hook. Ic. t. 80, are mere 

 forms of C. Bojeri, Hook. Ic. t. 10. 



Clematis microcuspis, n. sp. 



Volubilis, ramulis pubescentibus, foliis longe petiolatis deltoideis pin- 

 natim 5-foliolatis, foliolis cordato-ovatis facie subglabris dorso dense
