64 THE VOYAGE OF H.M.S. CHALLENGER, 



strongly keeled, and the long awns spread and curve downwards only with age. Curiously 

 enough, the ovary in all the flowers examined bore three distinct styles ; this was so in 

 flowers from different spikelets from the same specimen. In a quite young state the ovary 

 is glabrous, and the ripe caryopsis also ; but some unfertilised misshapen ovaries of inter- 

 mediate age were found, which were a little hairy about the upper part. No trace was seen 

 of the hairy appendage characteristic of the genus Bromus. The ripe caryopsis is about 

 three lines long, free from the glume and pale, though very closely invested by them. 

 We have found nothing at all like this grass from the mainland, and it differs even more 

 from the ordinary Bromus than the somewhat anomalous species of Agrostis, endemic in 

 the Tristan da Cunha group and St Paul Island, do from the normal Agrostis.

Of this curious grass we have seen only one specimen, sent to Kew by Philippi himself 

 in 1861. The prolongation of the rhachilla beyond the single floret of the spikelet, is a 

 striking characteristic of the genus ; the same thing occurs in the otherwise very different 

 Gymnopogon.

A very common American grass, ranging from British Columbia southward to Pata- 

 gonia ; commonly cultivated under various names, and now naturalised in many other 

 countries.

Also in Chili, according to Steudel, who cites the numbers 117, IIS, 861, and 1411 

 of Bertero's collection. The name is not included in Philippi's list, neither is it taken up 

 in Walper's Annales, and the sixth volume of Gay's Flora Chilena, which contains the 

 grasses, was published two years before Steudel's Graminere. Desvaux, who elaborated
