0. serratum. — Habit and inflorescence very like 0. 



macranthum. Peru, 1850 (c). 

 0. SPHACELAtum. — A very easily grown and showy 



species, producing large panicles of flowers. 



Mexico, 1840 {%). 

 0. SFLENDiDUM. — Flowers exactly as in 0. tigrinum, 



but of entirely different habit, the pseudo-bulbs 



and leaves being a bronzy green, the latter thick 



and leathery in texture. Guatemala, 1870 (h), 



(Fig. 74). 



0. superbiens. — Of rather stronger habit than 0. 

 macranthum (similar to 0. undulatum). Flowers 

 white, yellow, chocolate, and purple ; the lip very 

 deeply tinted. New Grenada, 1847 (c). 



0. TETrapetalum. — Very small but extremely pretty. 

 Yellow, chestnut, and crimson. A difficult plant 

 to cultivate. Tropical America, 1832 (?'). 



0. tigrinum. — One of the very best of cool orchids. 

 Blossoms as fragrant as violets ; lip yellow ; 



sepals and petals streaked with brown. Mexico, 

 1839 (e). 



0. varicosum. — Very bright and showy ; a well- 

 known species. The variety Eogersi is much 

 larger than the type and a very fine orchid. 

 Brazil, 1846 (1). 



0. Warscewiczii. — Distinct species, with flowers 

 uniformly yellow. Costa Eica, 1870 (i). 



0. Wentworthianum. — A neat, small-flowering 

 species, with the habit of 0. incurvum. Guate- 

 mala, 1839 (c). 



0. zebrinum. — Very attractive, with pseudo-bulbs 

 occurring at 3 inches or more apart on a creeping 

 rhizome. Flowers on very long spikes, each 

 about li inches across ; pure white in ground, 

 with zebra-like stripes of reddish brown on the 

 sepals and petals ; lip white with red spots. 

 Venezuela, 1847 (c). 



orchis. — A genus of hardy terrestrial orchids that obviously gave the name "orchid" 

 to the family. There are several species indigenous to Britain, and all thrive in a cool, 

 moist and shady part of the garden in light loamy soil. The commonest British kinds 

 are 0. mascula, 0. maculata, 0. latifolia, and 0. pyramidalis, while good for 

 naturalising in this country are — 0. foliosa, 0. spectabilis, 0. purpurea, 0. Bobertiana 

 and many others. Most of the species may be procured at nurseries as dormant roots in 

 the autumn and early winter, and this is the most suitable time to make plantations. 



ornithocephaltjs grandiflortjs. — A plant that succeeds in small pans or on a 

 block of wood in the Cattleya house. It is known as the Bird's Head orchid, and has 

 greenish and white flowers (//). 



pachystoma thomsoniana. — A tropical African orchid with pure white flowers, 

 except the lip, which is purple. It thrives in the warmest house in a shady position, 

 and should be grown in rather small pots in a compost of peat fibre and moss over good 

 drainage (h). 



paphinia. — In habit the plants in this genus resemble Lycastes in a small state, and 

 their structure is very similar. They thrive best in small suspended pans or baskets, 

 where they will be protected from direct sunlight, this being injurious to the foliage. 

 They are subject to insect attacks, and require great care to keep them clean. 

 The species most generally grown are : B. cristata. — Flowers white, heavily spotted 

 and blotched with chocolate-brown. Trinidad, 1834 {h\ B. grandis.— Large flowers, 

 sepals and petals creamy-white spotted with chocolate-purple ; lip almost black-purple
