(its Arabian name). ORD. Leguminosae. Manna Tree. Greenhouse shrubs or sub-shrubs, with simple leaves, and minute stipulas. Flowers few, in clusters. They thrive in pots filled with a mixture of sand, loam, and peat. Young cuttings will root in sand, with a bell glass placed over them, in heat; but by seeds, if they can be procured, sown in a hotbed, is a preferable mode of increasing the plants. They may be placed out of doors during the summer months.
