Linum trigynum, one of our oldest stove or warm greenhouse plants, is one that is rarely seen in cultivation at the present time; but as it is to be found enumerated in a few of the catalogues of our florists, I am induced to call the attention of our amateur cultivators to it as, when well grown, a very attractive plant, and besides, the color of its flowers (bright yellow) is wanting in so many of the plants in cultivation at the present time.

Properly managed this Linum is an attractive warm greenhouse plant, growing from 2 to 3 feet in height by as much in breadth, having erect, smooth stems and oblong, acute, smooth alternate leaves; producing its bright yellow flowers from the axils of the leaves in the greatest profusion during the winter months, the time of blooming depending in a great manner upon the temperature in which the plants have been grown.

This Linum is a native of the East Indies, from whence it was introduced in 1799, and although it has been in cultivation for so many years it is a plant rarely met with. It is a plant easily cultivated, growing freely in a compost of two-thirds well decayed sods, one-third well decomposed manure, with the addition of a little sand. Mix thoroughly and use the compost rough. The plants should not be over-potted, and care should be taken to drain the pots well, for as the roots are small they cannot endure an immoderate supply of water. During the summer season the plants can be planted out in a well enriched deep border, and liberally supplied with water during seasons of drought. Early in September the plants should be taken up and potted, and on the approach of cool weather brought inside, where they should be given a light sunny situation, and an average temperature of 550. Water must be carefully given at all times, a liberal supply both overhead and at the roots during their season of growth, and afterwards more moderately.

Unfortunately it is very subject to the red spider, and on this account it must be freely syringed at all times, and every available means employed to keep these destructive pests in check.

Propagation is effected by cuttings of the half ripened wood, placed in sand in a gentle bottom heat, and if the young plants are liberally treated and shifted as often as necessary, nice specimens will soon be obtained. Unfortunately it is of no value for cut flower purposes, the individual flowers lasting for a few days only; but as a decorative specimen plant for a warm greenhouse, it is well deserving of attention. The beautiful bright yellow flowers and the profusion with which they are produced for a considerable length of time are all desirable points in its favor. And as it is an easily managed plant nice flowering specimens can be obtained in a short time. I think it deserving of a place in all amateur collections of rare and beautiful plants. And in order to avoid answering numerous queries as to where plants can be obtained, I may be permitted to state here that I have no plants or cuttings to spare, nor do I know where they can be obtained.
