512 ORCHIDS 



Zygopetaluin. 

 Z. Qautieri {Lem.). — This species is very attractive. It differs 

 ctiiefly from Z. maxillare in tiie flowers being about half as large 

 again ; they are also, as a rule, deeper in colour, especially on the 

 fleshy labellum, which in good varieties is a very deep purple- 

 blue, with a still darker-coloured crest. There are also varieties 

 with pale-coloured flowers. The species is a native of Brazil, 

 and was introduced in i86S. It requires the same treatment as 

 Z maxillare. It is not unusual for dealers to call good varieties 

 of Z. maxillare by the name of Z. Gautieri. (W. O. A., t. 28.) 



Z. gramineum {Rchb. f.) — This species is singular in not 

 possessing any pseudo-bulbs, the leaves rising in a fan-like manner 

 directly from the root. They are jointed about lin. from the 

 base, lance-shaped, channelled, 6in. long, and bright green. The 

 flowers are produced in clusters from the bases of the leaves, 

 each on a separate scape, which is about 2in. long and decumbent. 

 In form and colour the flowers are like those of ^. stapelioides : 

 but the sepals and petals are narrower, and thinly spotted with 

 rich deep brown, whilst the lip is oval, with scarcely any side 

 lobes, the margin crisped, and the colour yellow, shaded with 

 rose and blotched with crimson-brown ; the large column is 

 yellow at the top. This plant is not common in cultivation. It 

 has been called Kefersteinia, Maxillaria, and Promencea. Brazil, 

 1857- 



Z. intermedium {Lodd.). — A handsome, free-flowering, easily- 

 grown species, and so like Z. Mackaii as to be often mistaken 

 for it. The main difference between the two is that in the latter 

 the lip is glabrous, and the veins are coloured pure blue, whilst 

 in Z intermedium the lip is more or less hairy, and veined 

 with purplish-blue. Z. crinitum is another species very similar 

 to these two ; indeed, there does not appear to be any good 

 botanic characters to separate them. In Z. iiitermediiim the 

 pseudo-bulbs are large and egg-shaped. The leaves are strap- 

 shaped, about i^ft. long, i\\n. broad, and bright green. The 

 scape is erect, as long as the leaves, and it bears about six 

 flowers, each nearly 3in. across. The sepals and petals are 

 equal, i\\n. long, incurved at the tips, green, with large, con- 

 fluent blotches of brown. The lip is liin. across, wavy, narrowed 

 to a stalk-like base, and coloured bluish-white, with radiating, 

 broken lines of purplish-blue ; the disk is fleshy and white ; the 

 column is thick, winged, and coloured green and white. The 

 flowers are produced in winter, and last for about two months.

Z. Klabochorum {Rclid. f.). — One of the most beautiful of its 

 species. It has the typical strap-shaped, tufted, dark green leaves
