ZYGO-BATEMANNIA. 



Masters! is a bigeneric hybrid Orchid (ord. 

 Orchidacese) produced from Batemannia Colleyi X 

 Zygopetalum crinitum, and is intermediate between 

 the two parents ; sepals and petals green, marked 

 brown, lip white, purple. (For culture, sec ZYGO- 

 PETALUM.) 



ZYGO-COLAX. 



A group of hybrid Orchids (ord. Orchidacese) 

 obtained by crossing Zygopetalum with Colax. (For 

 culture, see ZYGOPETALUM.)

ZYGOPETALUM. 



Description, A large genus (ord. Orchidacese) 

 of epiphytal stove and greenhouse Orchids, all from 

 the warmer parts of America. Bollea, Galeottia, 

 Huntleya, Kefersteinia, Pescatorea, Promensea, and 

 Warscewiczella are all now included with the Zygo- 

 petalums. The flowers, which are, in not a few 

 cases, large and showy, are usually produced during 

 late autumn and winter, and upon some of the 

 species they last a long time in good condition. 



Propagation. By division and imported pieces. 



Soil. Fibrous peat from which all the finer 

 particles have been shaken, and chopped sphag- 

 num. Mackaii thrives with a little fibrous loam 

 added. 



Other Cultural Points. All the Zygopetalums 

 are shade loving subjects, but they vary a good 

 deal as to the treatment required. What may be 

 called the true Zygopetalums, as typified by 

 Mackaii, may be grown in pots along with the 

 warmth-loving Cattleyas. The Promensea section 

 does best in pans, nearly filled with crocks, and 

 hung up close to the glass in a cool house during 

 summer, and in a warmer (intermediate) one in 

 the autumn, winter, and early spring. All the 

 species with creeping rhizomes thrive if fastened 

 to blocks of wood Birch preferably, with the 

 bark on. Gramineum, and other species like it, 

 do well in small Teak baskets. The atmospheric 



moisture must be equable, and, as much diffused 



light as possible should be given. Disturb Hie 

 roots only when the compost is inclined to become 

 sour, thus rendering a shift inevitable. (For hybrids 

 raised between Zygopetalum and Batemannia, see 

 ZYGO-BATEMANNIA; between Zygopetalum and 

 Colax, see ZYGO-CoLAX.)
