Genus 23. CLASMATOCOLEA, Spruce. 



Clasmatocolea, Spi^uce Hep. Am. et And. p. 440 (1885). 



Plants small, fragile. Primary stem short, sub-erect, densely 

 leaved ; radiculose at the base — sometimes under the terminal 

 flower also ; producing slender, arcuate branches having small and 

 distant leaves, and often rooting at the decurved apex. Leaves 

 alternate, subsecund, ascending, plane or concave, obovate, 

 rotundate, subtruncate or retuse ; branch leaves very often ob- 

 cordato-cuneate. Stipules half the size, heteromorphous, most of 

 them ovato-lanceolate and entire, but others (chiefly the upper 

 ones) bifid. Inflorescence dioicous ; $ bracts larger than the 

 leaves, somewhat similar. Perianths large for the size of the 

 plant, very fragile, obovate or sub-conical, in the upper part 

 obscurely or very slightly trigonous, having a wide 2-4-lobed 

 mouth. Capsule oblongo-globose, in other respects like that of 

 LophocoJea.
