JUNCE/E. [Juncus. 



bear fruit, and is perhaps a morbid state of the plant. Its quite smooth stems, and deep-coloured flowers, 

 readily distinguish it from all forms of X effusus and glaucus. — The very sportive character of this and the 

 preceding species, as shown in the present collection, almost induce me to return to ray former opinion, that 

 they are not really distinct.

Hab. Saskatchawan to Bear Lake and English River. Dr RicJiardson. Drummond. — The J. Jiliformis 

 of Pursh is probably the J. setaceus, Rostkow, a different species, according to specimens from Dr Torrey, 

 gathered in Middle Florida ; being a larger and harsher plant, with very rigid glossy sepals, spreading nearly 

 horizontally around the almost depresso-globose mucronated capsule, I have excellent specimens, however, 

 of the true J. Jiliformis, from the United States, gathered by Mr Greene on the White Hills, New Hamp- 

 shire. It seems, therefore, in America, to be an alpine or very northern species.

Hab. Canada, to the Slave Lake, and to the marshy ground in the Rocky Mountains. Dr Richardson, 

 Drummond. — /3. Canada, Dr Richardson. Mrs Sheppard. — I am quite unable to distinguish this American 

 Juncus from our European J. acutiflorus. The whole habit of the plant, the flowers, and the fruit, are the 

 same. It is also nearly allied to J. lampocarpus, but that has larger flowers and capsules, and the latter 

 especially of a much darker colour. The var. /3. is a smaller plant, and has the capitula very few-flowered.
