Caulis 10-20 cm. longus, striatus, leviter alatus, tenuis, glaber. Folia linearia 
4-20 mm. longa, 1-2 mm. lata, subobtusa vel brevissime mucronata, quam 
internodia breviora, sæpe duplo vel triplo breviora, vel etiam ea subæquantia. 
Racemi capitati 10-20 mm. longi, 6-8 mm. lati, subdensiflori, sæpe longe pedun-
