Proxima C. filipendula facile clignoscitur peduneulis lawibus 

 spicis densifloris, perigyniis lsevibus cet. C. rariflora Sm. haud 

 ita absimilis est, quam e diagnosi crederes; hiculenter autem 

 differt stigmatibus 3, spicis (approximatis) bracteis peduncu- 

 lisque (lavibus) multo brevioribus, squarnis lato-ovatis, obvolvent- 

 ibus, ligula elongata cet. Prseter has nullam scio, cum qua 

 nostram comparare necesse esset." 



According to Grcenlund 6 the species has been collected 

 near Olaf sdalr by Japetus Steenstrup, and near Grimsnes 

 by himself; unfortunately we have no information 

 about the other species with which it may have been 

 associated, but the two stations mentioned are not among 

 those from where Grcenlund has recorded C. cryptocarpa. 

 In this connection may be stated that only typical 

 C. salinah&s been found in Iceland, where it is very rare, 

 however. 



The lax-flowered pistillate spikes born on scabrous 

 peduncles (fig. 7), and the perigynium being scabrous 

 along the superior margin, (fig. 10) are characters which 

 have not been observed in C. cryptocarpa; moreover the 

 species has never, so far, been found in the regions where 

 C. cryptocarpa abounds : on the shores of the Pacific 

 Ocean and Bering Sea; it also deserves mention that 

 dwarfed and very slender specimens of the latter (from 

 Alaska) deviate in no respect from the type except by 

 their diminutive size and very small spikes. 



By comparing the diagnoses and figures of C. crypto- 

 carpa and C. capillipes it certainly appears as if both 

 are species distinct, and until more material has been 

 collected and further observations have been made, we 

 prefer to consider them as such. 



Car ex prionocarpa Franch. 



This species, described by Franchet, 7 shows the same 

 habit as C. cryptocarpa; it is stoloniferous, the bracts 

 are foliaceous, and the spikes number from 5 to 7, 3 

 staminate, and 3 to 4 pistillate ; the scales of the pistillate 

 flowers are fuscous, obtuse, generally shorter and nar- 

 rower than the perigynium (kg. 11) ; the perigynium is 

 glaucous, ovate-oblong, spinulose along the margins and 

 the nerves, and the beak is very short, with the orifice 

 entire; the style is bifid. The species is a native of 

 Japan : the island of Yeso.
