Var. sterilis Syrhe. Sparingly in the same locality. This 

 latter plant is the c G. fuha Koch according to Syme E.B. III.; 

 and it is evident that continental botanists apply the name fulva 

 to some plant other than Homschuchiana. - 



C' ampullacea Good. f. androgyna. U. by the Mailand 

 Burn there occurs abundantly a large luxuriant form, which has 

 all the female spikes male at the apex ; the male portion varying 

 from J to i J inches in length. I do not discard the well-known 

 name for this plant until it is decided whether it should be called 

 G. obtusangula Ehrh., or G. rostrata Stokes. 



Agrostis canina L. var. mutica Gaud. (t. Hackel). On 

 the Sneug, island of Foula. 



X Deschampsia discolor Rom. et Sch. {Air a setacea 

 Huds). S. Very sparingly by the east side of Tingwall Loch. 



Of the Ferns, Athyrium Filix-foemina, Blechnum 

 boreale, and Lastrea dilatata are the commonest and most 

 generally distributed. 



X Isoetes lacustris L. U. Loch of Cliff ; Loch of Watlee. 

 S. Tingwall Loch ; fairly common in all the stations. 



Dragonflies. Mr. W. Harcourt Bath, Ladywood, Birmingham, desires 

 to correspond with students of the Odonata in all parts of the globe, as he is 

 specially making up this group of insects. Specimens for figuring in his forth- 

 coming "Monograph of British Dragonflies " will be very acceptable. There 

 is probably no class of insects so neglected as Dragonflies ; and Mr. W. 

 Harcourt Bath will be very pleased to assist everyone desirous of commencing 

 their study.
