Structure cellular; the cells quadrate, something largerthan in E. intestinalis. Colour a pleasant grass-green. Had not this plant been admitted to the rank of a species bythe late Capt. Carmichael, than whom few naturalists have morecarefully studied this variable genus, I shoidd have been con-tented to regard it, with continental authors, as a dwarf varietyof E. intestinalis. Capt. Carmichael says, Without pushingthe system of varieties to an extravagant length, this plantcannot be considered as a variety of E. intestinalis; the cha-racters of the definition mark it as abundantly distinct, and tothese characters it is universally constant.
