Lough Neagii, and other places in the County of Antrim. Mr D. 

 Moore. FL June, July. If. — This is one of several interesting dis- 

 coveries, for which we are indebted to Mr Moore's unwearied exertions 

 in Ireland. It is from to 2^ to 3 feet high ; its leaves narrow, rigid, 

 convolute when dry, and like the following species has a minute scale or 

 short pedicel, the rudiment of a second flower, bearing a tuft of hairs at 

 the extremity ; the distinguishing character of Deyeuxia. The flowers 

 are at first singularly tinged with purplish-blue, in age becoming yellow- 

 ish-brown. Branches of i\\e panicle spreading during the short period 

 of flowering ; before and after, erect, compact.
