P. QUERCETICOLA, Lindl. (i'). — A distinct and free-growing species, 

 inferior in beavity to the silvery reticulated kinds, but interesting from its 

 dissimilarity. It grows from 3 to 4 inches high or more, and has ovate acute 

 leaves 2 to 3 inches long, of a light green colour, with blotches of silvery grey 

 on each side the mid-rib, appearing as if the intervening spaces and not the 

 veins were silvered over ; the flowers grow in lax spikes, and the lip is three- 

 toothed at the apex. — Said to come from Java, but Lindley's plant is a native 

 of JSfew Orleans. 



PILUMNA, Lindleij. 



(^Trlbe Vandeae, sttbtritje Oncidieae.) 



A small group of dwarf-growing epiphytes, closely allied to Aspasia and 

 Trichopilia, with which latter some authorities unite them. They differ, 

 howevei^ not only in their aspect, but also in their sub-entire lip, which is 

 adnate to the column and rolled roiind it at the base, and in the cucullate 

 anther-bed being surrounded by membranaceous teeth. The few species 

 are found in Central America, Mexico, Venezuela, and New Grenada. 



Culture. — The species of Pilumna, succeed well in the cool house, 

 and are best grown in pots with rough peat, charcoal, and sphagnum 

 moss ; thejr require good drainage, as an ample supply of moisture is 

 requisite during the growing season, but during the resting period less 

 should be given. In potting the plants should be well elevated above 

 the pot rim. They are propagated in the usual way, by division. 



P. FRAGRANS, Lindl. — This plant, which, as already noted, is very like 

 Trichopilia in habit and appearance, has delioiously sweet-scented blossoms. 

 The pseudobulbs are oblong, 4 to 6 inches long, slightly compressed, mono- 

 phyllous, the leaves broadly oblong-lanceolate, and the flowers produced in 

 pendent racemes of three or four together on radical peduncles ; the sepals and 

 petals are oblong-lanceolate acuminate, pale yellowish-green, 2| to 3 inches 

 long, wavy and slightly twisted, and the lip, which is oblong, is apiculate and 

 slightly three-lobed, pure white, with an orange spot towards the base. It 

 blooms during the winter season.- — New Ch'enada.

 worthy of cultivation on account of its delicious perfume ; the scapes are
