 around El Paso, May ; in flower. — Mr. Wright has callcd my attention to a sin- 

 ^ular structure of the leaves in this plant, which is well shown in the growing 

 shoots of some of the specimens ; namely, that the spines are the persistent petioles 

 of the cauline leaves, or rather a dorsal portion of theni, to which a long and 

 slender downward prolongation of the blade of the leaf is adnate for its wholc 

 length, and from which it separates, when fuU-grown, froni the apex to thc base. 

 The foliaceous portion soon falls away, leaving the long and naked spine, from the 

 axil.of which a cluster of subsessile secondary leaves is developed. The spine itself 

 is decurrent on the stem into an elongated puhinus or ridge, which extends down- 

 w^ard quite to the next axil directly underneath.

H. B. K. has recently (in Konsd. Danske VideiisL Selk. Skrifi 



characterized and fir^urcd by Liebmann as a new and anomalous genus of Polemoniaceffi, namcd P/u7e- 

 iceria Iwrrida. From the details of the seeds, it appears that the wing diffcrs from that of F. splendens 

 in being deeply cleft at both ends. — Kunth writes the name Fonquieria ; but De CandoUe, Endlicher, 



&c. write it Fouquiera.
