Mygalurus. Named by Link, from μuγaλη, a mouse, and sea, a tail. An alteration of the previous specific name of one of the species, Festuca myurus, L. A natural genus, better distinguished by natural than by artificial characters. 184. Bromus. Bρωμoς is the name given by the Greeks to a sort of wild oat. Most of the species of this genus are of a coarse quality, and being strictly annuals are of little value as pasture, and as hay produce no after math. Sir H. Davy found that the nutritive powers of the straws and leaves of most of the species were greatest when the plant is coming into flower; because, like all other plants strictly annual, or which do not shoot up again from the root the same season, when left till the seed is ripe, the leaves and straws become dried up. B. secalinus is often found among rye and wheat crops; the seeds when ground among the flour are said to impart a bitter taste to bread, and to have similar narcotic qualities as Lolium temulentum. In Scania, the panicles are used to dye green; and there, as formerly in Britain, rye was supposed to degenerate into this grass. The seeds of B. mollis are said to bring on giddiness in the human species and quadrupeds, and to be fatal to poultry. B. asper is the tallest of British grasses; it has had many names, but is distinguished from all ORDER II.

It is found in copsewood in clayey moist soils. Bromus giganteus partly resembles it. 185. Brachypodium. From βρaχuς, short, and 785, a foot, in allusion to the short stalks of the spikelets. An artificial genus, made up of various species of Bromus, Festuca, and Triticum of former writers. 186. Uniola. Named by Linnæus, on account of the union of the glumes. A fine N. American genus, resembling a gigantic Bromus or Festuca. It is chiefly found upon the sands of the sea-coast. 187. Tricuspis. A word signifying three points, in allusion to the structure of its flower. This grass is called Red -top in the southern states of N. America.

Pursh says, "a most excellent grass. I have seen mountainmeadows in Pennsylvania where they mow this grass twice a-year, producing most excellent crops cach time without manure or any other trouble than the mowing, lasting for the space of sixteen years without the least decline in the crops, the soil at the same time being a very indifferent one." 188. Diplachne. Δiπλoς, divided, aχvη, chaff. The outer palea is divided at the end, and bearded between the divisions.
