 Ch(€tospora rhyncosporoidcs^ Steud.= Carpha paniculata^ Plul. This 

 was first described by Sir Joseph Hooker in the ' Plora Antarctica* 

 from a specimen collected by Darwin at Cape Tres Montes ; and 

 a second species, Chcetospora antarctica^ is described and figured 

 in the same w^ork from a specimen, also collected by Darwin 

 above Cape Tres Montes. This latter appears to be a mountain 

 variety of the common species, which extends from the Cordillera 

 de Rauco in Chili to the Channels of Patagonia, but has not been 

 found so far south as Fuegia or the Straits of Magellan. The 

 only grass collected was HieroMoa antarctica, 3i. Br., var. = -Zr. 

 altissiyna, Steud. With reference to the last-named species I 

 may add the remark that, with the single exception of II. tereti- 

 folia^ Steud., all the specimens of HierocMoa that I have seen 

 from Chili or Magellania appear to me to be referable to H. ant- 

 arctica of R. Brown, under which should be ranked as synonyms, 

 or as varieties, H, altissima^ Steud., H, redolens, E. S., U. magel- 

 lantca^ Hook, f., H. utrictilata, Kunth, and //. arenaria^ Steud. 

 The characters drawn from the smoothness or roughness of the 

 sheaths or leaves, and the presence or absence of hairs on the palese 

 seem to be unreliable, as these vary among plants growling in the 

 same locality, and even the relative length of the glumes varies 

 considerably. 



The forest at Eden Harbour appears to consist altogether of 

 JPff^i^s J^/m7o/J^s, Mirb., and the deciduous species {P. antarctica) 

 was seemingly uncommon in the northern part of the Channels. 

 It is, however, very difficult to distinguish the closely allied 

 species F. betuloides and F, Domheyi, and they may grow together 

 at Eden Harbour, as they certainly do at Hale Cove, somewhat 

 farther north in Mcssier^s Channel.
