separate plants of Tillandsia.” In our Bladder-roots, again, 
there are no leaves; but bladders (as the name implies) 
among the roots, which enable the plant to float and bring its 
blossoms above the surface of the water. In the Brazilian 
species there are the bladdered roots; and, besides, peltate 
leaves, 3 inches across, on long footstalks; while the flower- 
stem bears numerous large purple flowers. 
The volume is well got up by the spirited publishers, 
Messrs. Reeve, Brothers, and is accompanied by a beautiful 
view of the Organ Mountains and a map of the route, highly 
necessary for the information of the reader. 
LixpLEY!'s “ Orchidacee Lindeniane." 
Dr. Lindley, whose labours in illustrating the Orchidaceous 
plants, both by splendid figures and descriptions, are 
beyond all praise, has here again favoured the botanical 
world with a brochure of twenty-eight pages, describing 
143 species of plants of this family, from the dried specimens 
collected by Mr. Linden in Columbia and Cuba; no fewer 
than 77 are wholly new to science, including 3 new Genera. 
Of these latter, the most remarkable is Uropedium, Lindl.; 
having all the character of Cypripedium, and the habit of 
the East Indian Cypr. insigne ; except that the lip, instead of 
being slipper-shaped, is pes and the petals are nes 
into long tails. —— — 
There are given also some » interesting mese" on (de 
elevation above the sea, and the mean temperature, where 
the species are found :—for example, only one species (Epi- 
dendrum frigidum) is found at an elevation of from 12,000 
to 13,000 feet, where the mean temperature is 40o.— Six 
at from 11,000 ; mean temp. 469.— Thirteen at from 10,000 
to 11,000 feet; mean temp. 499.—' Twenty at from 9,000 
to 10,000 feet; mean temp. 529.—Nineteen at from 8,000 
to 9,000 feet; mean temp. 56°—Sixteen at from 7,000
