B. verrucosa is readily distinguished from B. caudata, B. Lanceana, and B. macrostachya, by the 
obovate (not oblong, oval, or ovate) form of the labellum, and from B. maculata by the great disparity 
between its sepals and petals. Another peculiarity is to be found in the little green warts which are 
profusely scattered over the lower parts of the labellum, and which suggested to Professor Linpiry the 
specific name. (Vide Bot. Reg. Misc. 1840, No. 66.) B. verrucosa also differs from its congeners in 
the form of the pseudo-bulbs, which are rounder at the edges than in the other species, and likewise more 
deeply furrowed ; their colour, too, is darker. 
As regards culture, the treatment ordinarily applied to Orchidacew will be suitable for B. verrucosa; 
the plant, however, is a slow grower. It flowered at Tooting in April, 1840. 
In the Vignette are seen the famous Chinampas (or floating gardens) of Mexico, of which Humsotpr, 
in his “Personal Narrative,” has given such an interesting account. They occur in the River Chalco, 
about ten miles from the capital, and owe their singular appellation to the circumstance of their having 
been formed upon what were originally drifting masses of reeds, roots of trees, &c., which, acquiring con- 
sistency by degrees, were at length compact enough to support a fresh vegetation of their own. ‘Their 
peculiar fitness for what we call “kitchen gardens” seems to have early attracted the quick eye of the 
Indians, and the care still taken of them by these industrious people is sufticiently attested by the rich 
variety of fruits and vegetables which they furnish daily to the markets of Mexico. ‘In fine evenings,” 
says HumpBoxpr, “hundreds of canoes, crowded with Indians neatly dressed, their heads crowned with 
the most gaudy flowers, are seen passing in every direction; each boat with its musician, and some of the 
party singing or dancing, or both.”
