described by Mr. Babington, in the third edition of his Ma- 

 nual (343). It was characterized by Chamisso, in the ' Lin- 

 naea' (ii. 4), and belongs to that division of the genus which 

 has all the leaves submerged, alternate, and linear. It differs 

 fi-oin its congener and near ally, P. pusillus, of Linneus, in 

 having the leaves one-nerved. Chamisso and Schlechtendal, 

 as well as Hooker & Arnott, regard compressus and pusillus 

 merely as forms of the same plant. P. trichoides has only 

 been found in the vicinity of Norwich. 



II. Additional or Rediscovered Localities for Rare Plants. 



Euphorbia Peplis. — Mr. E. T. Bennett (iv. I) restores this local 

 plant to its old Cornish locality on Marazion Green, where it 

 had been supposed extinct. 



Cystopteris montana. — Mr. Borrer (iv. 7) and Dr. Arnott have 

 found this fern in the range of mountains between Glen 

 Dochart and Glen Lochay, on the same spot where Messrs. 

 W. Gourlie and W. Adamson found it in 1841. Hooker & 

 Arnott, in the sixth edition of the ' British Flora,' spell the 

 name of the place thus : — " Corrach-Uachdar ;" but Mr. Bor- 

 rer understood the name of the mountains as " Meal Oufil- 

 lach," and of the ravine, " Corrach Dh'Oufillach," as nearly 

 as he could express in writing the pronunciation of the native 

 from whom he received the information. 



Menziesia ceerulea. — This plant also was I'ediscovered by Mr. Bor- 

 rer (iv. 7), in Drumochter, or Drum Uachdar, on the confines 

 of Atholl and Badenoch. Mr. Borrer found several tufts, 

 growing among the heath and cranberry. I may mention 

 that the late Mr. Cameron, formerly of the Botanic Garden 

 at Birmingham, told me, some years ago, that he had many 

 times visited a spot where it grew in some abundance, that 

 he could find it at any time, and that there was no probabi- 

 lity of its becoming exterminated. Mr. Cameron, I may 

 add, was well known as a man of the most scrupulous vera- 

 city.
