in existence: C, tribuloides, leptalca, Pyrciiaica, grisea, prasina^ 

 xantJiopJcysa. In Thunberg's herbarium, at Upsala, is a speci- 

 men called C. hiifolia, but evidently not labelled by Wahlcnber<^ 

 himself, and it is C. plantaginca, Lam., as commonly supposed. 

 The figures in Schkuhr with which Wahlcnberg compares his C. 

 grisea and C. tribiiloidcs are unmistakable, and the conditions of 

 publication of C. leptalea also leave' no doubt as to the dispo- 

 sition of this species ((T. polytrichoides, Muhl.). Schkuhr's figure of 

 C. mtliacea, which Wahlenberg cites under his C prasina (Fl. 

 Lapp. 250), is less characteristic.
