Glauca, glabra, cespitosa. Canles adscendenti-erecti seu 
erecti, spe turiones foliosos edentes, graciliter tenues, 
simplices. Folia inferiora anguste lineari-lanceolata, acumi- 
nata, in petiolum longissimum attenuata, superiora elongato- 
linearia, longius acuminata, basi membranaceo-vaginantia, 
omnia uninervia, glabra; bractee e basi ovata caudato- 
acuminata, semi-herbacew. Flores in racemis simplicibus, 
brevius pedicellati. Calyx longe clavato-cylindricus, annulo 
circular! pseudoumbilicatus, fructifer infra capsulam admodum 
attenuatus, evenius. Petala albida (?) siccitate fuscescentia, 
biloba. Capsula oblonga carpophorum fere wequans. Semina

Described from specimens preserved in Herb. Kew. The name is derived 
from the slender flowering stems. 8S. avromana, S. Parrowiana, and 
S. tenuicaulis are distinguished from the other four species of the group 
in the calyx being without anastomosing nerves: though in S. caramanica 
the bifurcations of the primary nerves are very faint and scarcely to be 
made out.
