132 COOL ORCHID GROWING. 



very mucli inclined to become spotted with yellow on its 

 leaves ; for which the best remedy is to grow it exposed to the 

 light, and free from cold draughts. The temperature should 

 be maintained as equal as possible, free from sudden transitions, 

 and then it seldom spots. It lasts from four to six weeks in per- 

 fection. There used to be a noble specimen of it at Dalkeith, 

 and another at Grimston Park, in Lord Londesborough's 

 collection. The former plant has borne- twenty-eight flowers 

 on a single spike. 



*F. teres. — This is easily distinguished from its congeners 

 by its quill-like foliage and stems. Its large rosy-purple and 

 yellow flowers are freely produced on well grown plants from 

 June to August, and last from four to five weeks in perfection. 

 This is sometimes considered a shy-flowering species, but if 

 grown in a cool airy house, and fully exposed to the sun when 

 it is thoroughly well established, it will flower freely enough. 

 It does well in fibrous peat, sphagnum, and crocks in a pot, 

 and I have seen good plants of it trained on teak rafts. It is a 

 native of Sylhet, and makes a noble exhibition plant when 

 well grown. 



*a. V. teres Andersoni. — This is a fine variety of the normal 

 type, and by some is considered to flower more freely. 

 Zygopetalum. 



This is a genus containing one or two well known winter- 

 flowering Orchids of great merit. There are about a dozen 

 species introduced, and all of them grow well in the cool house 

 with plenty of air and moisture when making their growth. 

 They are nearly related to the Huntleyas, Warreas, and Pes- 

 catoreas. Z. maxillare and Z, Mackayi are two of the best 

 species in the genus. 



Z. aromaticum (Central America). — This is a rare and J^eau- 

 tiful species, bearing flowers four inches across. Sepals and 

 petals of a soft pea-green colour ; lip large and nearly cordate;
