I have no hesitation in claiming for this plant (the -ff. spinosa^ 

 var. glabra, of Martins, in the Mnnich Herbarium) the rank of a 

 distinct species. In turning over a number of specimens, there

 to be accompanied by narrower perfectly glabrous leaves, with 

 the mid vein very prominent beneath, and the glabrous sepals 

 always broadest at the base and gradually narrowing to the 

 apex ; the styles are also very seldom found attached to the ripe 

 capsules. A very marked, though minute, character is also fur- 

 nished by the seeds, which, instead of being deeply longitudinally 

 striated as in S. spinosa and glahra, are reticulated, and sur- 

 rounded by a membranous wing. I have given the species the 

 name of II. elegans, that of jH". glabra having been already appro- 

 priated by Schumacher. Great confusion in nomenclature has 

 been occasioned by Choisy's having altered the name of Schu-
