13. SirenNE Moncorica, Maxim., Enum. Pl. Mongol., p. 88, t. 13 
(1889). 
Caules cespitosi basi suifruticosi griseo-virides minute 
puberulo-scabri. Folia cartilagineo-apiculata, inferiora con- 
ferta basi attenuata lineari-lanceolata obtusiuscula, cetera 
linearia mucronata. Flores sub anthesi vix cernui, postea 
stricte erecti in dichasio 1-2-rarius 3-floro dispositi, pedicellis 
quam calyx longioribus. Calyx inflato-cylindricus, fructifer 
late clavatus, umbilicatus, dentibus subcordatis late hyalino- 
marginatis, Petala angusta emarginata, unguibus exsertis, 
appendicibus binis ovoideis. Capsula ellipsoidea carpophorum 
bis superans. Semina tuberculata, dorso plano-convexa, 
faciebus concaviuscula. 
Hab.—Northern Gobi; Mt. Tostu (1886). 
A species anomalous in habit, perhaps a connecting link between this and 
the next subgenus.

Jonge pedunculati. Calyx membranaceus ovato-campanulatus 
umbilicatus scabrido-puberulus, dentibus lanceolatis acutis cilio-
