lONOPSlDIUM (Greek, ri.jl.-l-tilcr }. Cruciferce. I. 

 (iciiiile is a pretty, tuftcil little plant, growing 2 or 3 

 inches high and bearing numerous smair4-petared, lilac 

 fls. from spring to fall. It is a half-liarily perennial 

 from Spain and N. Africa, but is treated as an annual. 

 It is desirable for edgings in moist, shady places, and 

 for rockeries. In rich garden soil the 'plants make 

 numerous runners. The fls. are about '.j in. across, 1 on 

 each stalk. They open white and turn filar. The plant 

 _ has been advertised as the Diamond Flower by seeds- 

 men. This plant is referred by Index Kewensis to 

 Gochlearia, a genus whose limits are very uncertain.

I0N6PSIS (Greek, tiio/,V-?(7,-e). Orcliiddeea>. A small 

 genus of epiphytic orchids, numbering about 10 species, 

 ujaiiy of which can probably be reduced to varieties of a 

 tew species. Most of the species are insiguiticant, only 

 one or two being cultivated. The flue specimen of /. 

 pnniriihifa figured in the Botanical Magazine has a 

 panicle 10 in. long, 8% in. wide, Avith 5 branches, and 

 aliout 80 Hs., each three-quarters of an inch across and 

 chiefly white, with violet markings near the center and 

 a dash of yellow". In its native country it is said to re- 

 main in attractive condition from Sept. to I\lay. The fls. 

 are produced so freely and over so long a period that it 

 is sometimes necessary to destroy the flower spikes, 

 which are out of all proportion to the number of lvs. 

 The plants succeed in the warndiouse under the same 

 treatment as Burlingt(jnias or the more delicate Oncid- 

 iums. 



lonopsis consists of tropical herbs without pseudo- 

 bullis, having very short stems, with few, narrow, 

 sheathing, coriaceous lvs.: sepals sube(iual, erect, 

 spreading, the dorsal one free, the lateral ones united 

 into a short spur behind; petals like the dorsal sepals; 

 labellum united to the base of the column, middle lobe 

 large, expanded, 2-3 times as long as the sepals, 2-lobed; 

 column short: pollinia 2: fls. small, in simple racemes 

 or much-branched panicles. 



panicul4ta, Lindl. Lvs. thick and channelled, linear 

 lanceolate, keeled, 2-3 in a cluster and about (i in. long: 

 panicle much branched and spreading, loaded with in- 

 numerable fls. of a delicate texture: sepals and petals 

 very short, sharp-pointed, the petals wider; labellum 

 very large, pubescent <at base, witlt a 2-lobed rounded 

 limli. which in some is almost entirely white, while in 

 others it has a spot of purple or vellriw on the disk.
