REPORT ON THE BOTANY OF THE ISLANDS OF THE SOUTHERN OCEAN. 269 



This very ordinary-looking grass has given us great trouble, and may after all turn 

 out to be some common species, though we have failed to match it. In many respects it 

 is like Agrostis vulgaris, and still more in aspect like Agrostis canina ; but the total 

 absence of an awn on the flowering glume removes all doubt as to its not being the latter, 

 and we cannot think it is a variety or state of the former. 



Agrostis delislei, Hemsl. (Plate XLIV.) 



Agrostis delislei, Hemsl., n. sp. 



Csespitosa, erecta, foliis brevibus margine scabridis, paniculis angustis, gluma florifera 

 lono;e aristata basi extus barbata. 



Perennis, 9-15 poll, alta, fere ubique glabra. Folia culmo multo breviora, crassiuscula 

 sed vix coriacea, obtusiuscula, siccitate marginibus involuta ; ligula ampla, integra, obtusa 

 vel fere rotundata. Paniculce subsessiles vel pedunculate, pedicellis pilis minutis rigidius- 

 culis instructis. Glumes exteriores subsequales, florenti duplo longiores, acutse ; gluma 

 florens bifida, basi barbata, dorso longe aristata, arista recta ; palea paulo brevior, oblonga ; 

 stamina 3, marcida. Caryopsis non visa. 



Amsterdam Island. — Among Sphagnum at about GOO feet — De Hide, 33. 



In structure this species approaches very near to Agrostis media, from Tristan da 

 Cunha.

Also recorded from Tropical America and Bourbon. 



We have not seen any Lycopodium from Amsterdam which could be referred to this 

 species or variety, for Lycopodium trichiatum is regarded by many botanists as a variety 

 of the widely spread Lycopodium clavatum, Linn. It is included here on the authority of
