SOBOLfWSKIA (named for G. Sobolewski, Rus- 

 sian botanist). Cruciferse. Erect paniculately branched 

 glabrous annual or biennial herbs, adapted to outdoor 

 use: Ivs. long-petioled, rotundate, coarsely crenate: fls. 

 in corymbose racemes, slender-pedicelled, without 

 bracts, white; sepals spreading, uniform at base: silique 

 clavate, compressed or nearly terete, curved, leathery, 

 1-celled, 1-seeded. Five species, Asia Minor and the 

 Caucasus region. 



clavata, Fenzl. Basal Ivs. reniform-cordate, the upper 

 nearly sessile: silique 2% lines long by 1J4 lines wide. 

 May. Asia Minor. F. W. BARCLAY. 



SOBRALIA (for Fr. Mart. Sobral, a Spanish bota- 

 nist). Orchidaceae. Extremely handsome terrestrial 

 orchids with a very distinct habit, some of them com- 

 paring well with cattleyas and Iselias in bloom. 



3624. Sobralia macrantha. ( X \i) 



Leaves with sheathing bases, plicate- venose: fls. 

 membranaceous, few, in short, terminal racemes, or 

 solitary; sepals and petals spreading; labellum convo- 

 lute around the column, terminal portion large, undu- 

 late, often fimbriate, smooth or with longitudinal 

 ridges; column slender; pollinia 8. About 30 or more 

 species, inhabiting the mountains of Mex. and Trop. 

 Amer. The following account comprises the species 



that appear to be in the American trade, but others are 

 to be found in the collections of fanciers. The plants 

 have slender reed-like sts. clothed with Ivs. throughout 

 their entire length. The sts. are tufted, forming bushy 

 plants varying in height according to the species. The 

 fls. are among the largest of the orchids, those of S. 

 macrantha attaining a diam. of 9 in. across the sepals. 

 They are, however, very transient, fading a few days 

 after opening. 



Sobralias are charming orchids, and when room can 

 be given to large plants they well repay the space and 

 care they require. Many of them, to be sure, are very 

 fugacious in their blooming, some lasting only a day, 

 but nearly all of them make up for this by a succession 

 of flowers which is more or less rapid. In size the indi- 

 vidual blossoms vary from that of an ordinary Cattleya 

 labiata to one scarcely 1 J/2 inches across, and the plants 

 themselves present as great variety, ranging from such 

 as S. fragrans, which grows less than a foot high, to that 

 giant of the tribe, S. Cattleya, which will reach a height 

 of nearly 10 feet. They also give as much variety in 

 their coloring, ranging from a shade of lavender which 

 is almost a blue through different shades of purple to 

 the rich claret-color of S. Lowii, and from yellow to the 

 purest white. Where space for large and bushy plants 

 can be afforded, some of the sobralias will prove most 

 charming plants, having the double advantage of pre- 

 senting in a well-grown plant not only beautiful blos- 

 soms but a subject which is thoroughly attractive as a 

 foliage plant. They also have the added advantage of 

 being, in most instances, of rather easy culture. Given 

 a suitable soil and a liberal supply of water they are 

 almost sure to grow and bloom, although they will do 

 better if they are given their time for rest, when less 

 water is allowed without permitting the material 

 about the roots ever to become quite dry. (F. J. Le- 

 Moyne.)
