and Miscellaneous Particulars. 
ture lands, on account of its prickly leaves. These, stripped of their pulp, soaked in water, and beaten witli a 
wooden maUet, yield a strong thread which is twisted into ropes and whips, and manufactured by the Spaniards 
into a good cloth. The juice of the fruit in water makes a cooling draught in fevers ; it is extremely diuretic, 
destroys worms, and makes a good vinegar. 
B. Karatas, so called from its Brazilian name, Karaguata-acanga, generally grows at the root of some shady 
tree, in hilly and woody places in America and the Caribbee islands. It is an elegant plant, producing nume- 
rous radical leaves, which are of a subulate-linear shape, sharp pointed, and edged with spines. The flowers 
are scentless, seated in the bosom or middle part of the plant, rose colored, with the calyx and germ downy. 
The length of the leaves is six or seven feet. The fruits are oval, two or three hundred in number, and grow 
sessile in a heap or central group, surrounded by paleaceous expanded leaves or bractes ; they contain a 
succulent whitish or yellowish flesh, under a coriaceous and yellowish bark. When ripe, they are far from 
unpleasant ; but when unripe they set the teeth on edge, and excoriate the mouth. The economy of this 
plant in the preservation of its fruit to maturity is wonderful : being so protected by the spines of the sur- 
rounding leaves, as to be secure from all injuries. 
B. humilis propagates itself by runners or shooting processes, which proceed from the axillse of the lower 
leaves, and produce a young plant from their extremities. 
Bromeha fastuosa is the most beautiful of the genus. It has never flowered more than once in this country, 
when the figure in Mr. Lindley's Collectanea Botanica was obtained. Bromelia sylvestris resembles this, but 
is less beautiful. 
727. Guzmannia. iJamed after Anastatio Guzman, an industrious apothecary, and zealous collector 
of objects of natural history in South America. A beautiful evergreen herbaceous plant, with the 
foliage of Tillandsia, and a spike of bracteae, the uppermost of which are richly colored with 
rose. 
728. Pitcairnia. So named by Mons. L'Heritier, in honor of William Pitcairn, M. D. an eminent physician 
of London, and a collector of foreign plants, particularly from the Alps. The species are remarkable for their 
long, narrow, green, prickly leaves, and for their uniform panicles of bright red. Pitcairnia staminea is very 
handsome. They require the same treatment as Bromelia. 
729. Tillandsia. So named by Linnaeus, in memory of Elias Tillandsius, professor of physic at Abo, author
