SMOKE TREE. Jihu.s CotUus. 



SMUT. A prevalent disease of many cultivated cereal 

 grasses and other plants caused by the attack of a 

 fungus of the class ustilagine*. sometimes producing 

 swellings on various parts of the host, the swellings 

 being eventually filled with brownish or blackish spores 

 known as chlamydospores, which emerge, as a fine dust- 

 like powder, when the outer membrane of the hyper- 

 trophic tissues bursts or cracks. The smut on Indian 

 corn may be taken as typical. The disease usually ap- 

 pears first on the leaves, afterwards at the junction of 

 leaf -sheath and blade; finally the ear of corn is attacked, 

 and the tassel. On the leaves blisters are found; on 

 the ear, large, whitish polished swellings appear. As 

 the spores mature, the swellings become darker in 

 color, and the inclosing membrane finally ruptures, ex- 

 posing the dark olive-green mass of spores. Unlike 

 most other cereals, maize can be inoculated at any age. 

 Several smuts have been described; viz., loose smut 

 of oats (Ustilago aveHa), maize and teosinte smut 

 (Ustilagozeai), stinking smut of wheat (TilMia tritici), 

 rye smut (Urocystis occulta), onion smut (Urocystis 

 cepul<f), and colchicum smut {Urocystin colchici). For 

 an account of the grain smuts, see Swingle, Farmers'

SOBEALIA (after Fr. Mart. Sobral, a Spanish bota- 

 nist). Orchidhcew. This is a genus of extremely hand- 

 some orchids with a very distinct habit. The plants 

 have slender, reed-like stems clothed with leaves 

 throughout their entire length. The stems are tufted, 

 forming bushy plants varying in height according to 

 the species. 'The flowers are among the largest of the 

 orchids, those of S. macrantha attaining a diameter of 

 9 in. across the sepals. They are, however, very fuga- 

 cious, fading a few days after opening. Lvs. with 

 sheathing bases, plicate-venose: fls. membranaceous, 

 few, in short, terminal racemes, or solitary; sepals and 

 petals spreading : labellum convolute around the column , 

 terminal portion large, undulate, often fimbriate, smooth
