Species 30. Trop ical America. Astrocaryums are elegant palms of medium height, very suitable for moderate sized conservatories. A. llurumuru, A. ./llearicanum and A.a1'genfeum are the kinds most commonly met with in collections. The lvs. are pinnate, and in small plants, at least in some of the species, the segments are narrow, four or five pairs of these alternating with two very broad ones. A. argum (emn has the under surfaces of the lvs. of a much lighter color than the others. In a young state, the plants require the temperature of the stove, and after attaining the height of a few feet they may be removed to a house where the temperature frequently falls as low as 45° F. Specimens 8-10 ft. high fruit freely. Prop. by seeds, which are slow in germinating. The soil in which they are sown should be changed occasionally, to prevent it from becoming sour. Be careful not to overpot, or the fleshy roots will decay. See Palms.
