Botanical: Melampyrum pratense (LINN.)
---Synonyms---Horse Floure. Triticum vaccinium.
Family: N.O. Scrophulariaceae
The Cow-wheat (Melampyrum pratense, Linn.) is an annual, with slender, branched stems, about a foot high, bearing stalkless, narrow, tapering, smooth leaves in distant pairs, each pair at right angles to those that are next to it, and long-tubed, pale yellow flowers which are placed in the axils of the upper leaves in pairs, all turning one way. The corolla is four times as long as the calyx, and the lower lip longer than the upper standing sharply out instead of hanging downwards as in most labiate flowers. The colour is somewhat between the delicate pale yellow of the primrose and the rich bright yellow of the buttercup. The plant is in flower from June to September.
Cow-wheat is said to afford fodder for cattle, though not cultivated in this country for that purpose. Linnaeus states that when cows are fed in fields where the Meadow Cow-wheat is abundant, the butter yielded by their milk is peculiarly rich and of a brilliant yellow colour, but in England the plant grows more frequently in the undergrowth of woods and thickets than in meadows, abounding in nearly all copses and woods throughout Great Britain.
The name of Cow-wheat is said to be derived from an extraordinary notion prevalent in some country districts among the peasantry of the Middle Ages, that the small seeds were capable of being converted into wheat, a supposition probably originating in the sudden appearance of the plants among corn, on land that had been recently cleared of wood.
Another reason for the meaning of Melampyrum is given in Lindley's Treasury of Botany, i.e. it refers to an ancient belief that the seeds, when mixed with grains of wheat and ground into flour tended to make the bread black.
The seeds, which bear some little resemblance to wheat, are generally eaten by swine, though they will not touch the herb. Cows and sheep are extremely fond of the plant, and Dr. Prior explains the name of the plant on the score that though its seed resembles wheat, it is only fit for cows. In old Herbals, we find it named 'Horse Floure' and also Triticum vaccinium. The generic name is derived from the Greek melas (black) and pyros (wheat), because the seeds made bread black when mixed with them.
Dodonaeus tells us that 'the seeds of this herb taken in meate or drinke troubleth the braynes, causing headache and drunkennesse.'
