The present species is readily distinguished by its slender habit 



and numerous ascending- leafv stems, of a beautiful green-, which 



are furnished with a few thin and scattered, short, glandular 



hairs ; by its long, slender, capillary peduncles ; and lastly, by 



its small, linear, pointed petals, scarcely exceeding the length 



of the calyx. I regret having been obliged to differ so widely 



in opinion from the Count de Sternberg, who certainly has not 



studied the present species with due care, as is evident from his 



description and figures, both of which are miserably defective in 



point of botanical accuracy. The following species, S. tenera, is 



distinguished from this, to which it is nearly related, by its much 



more tufted habit ; by its obtuse leaves, which, together with the 



stems, are thickly clothed with glandular hairs ; by the oblong 



laciniag of its calyx ; and in having the flowers double the size, 



with obovate, retuse petals, nearly twice the length of the calyx. 



In the figures of S. sedioides given by Sternberg, the petals are 



erroneously exhibited as obovate ; and were it not for the habit, 



which is clearly that of S. sedioides, I should certainly have been 



inclined to refer them to the following species. The figure given 



by him under the name of S. Hohenwartii shows the flowers much 



more correctly. The variety /S I have not seen : it therefore 



rests wholly on the authority of Sternberg, who states the petals 



and anthers to be of a purplish colour. The varieties I have 



marked agree with .S'. sedioides in every essential point ; but how 



far they are to be regarded as permanent varieties 1 have not had 



opportunities of determining.
