1862, p. 32, where Ca-psella Bursa-pastojis^ Mouch, plays a somewliat 
similar part. Of the leaves of AgeraHm poultices are made for 
tumours of every kind. 
Rosa de Berheria {Nermm odorum^ Soland). The name states that 
this plant has been introduced ; it came about fifty years ago from 
Portorico to Venezuela, The double red variety is the most common 
with us. Reputed to be poisonous, (Humboldt's "Rosa de Bel- 
veria " is Brownea racemosa^ Jacq. Syn. iv. 36.) 
Rosa de Montana ; Palo de Cruz {Brownea grandiceps^ Jacq.). An 
infusion of the flowers is a powerfiJ astringent, and was formerly much, 
used in curing dysentery. The wood is said to stop bleeding. (^5- 
clepias Curassavica, y, is reputed for doing the same.) 
Ruda {Rtita graveolens, L.). Cultivated in gardens, and used on 
account of its stomachic properties. 
Sangre de Dragon {Crotou sanguifluus, 11- B. and K., and C Jdbisci" 
folius^ H. B. and K. Syn. i. 406.) The resinous substance, known 
under this, is very astringent, 
Santa Maria {Pyrethrum Partlienium, Sm. Griseb. 380.) Culti- 
vated in gardens, and used instead of camomile {manzayiilla, whilst 
manzanillo is Hippomane mancinella^ L.). 
Sarrapia {Dipterix odorata^ Willd.). The seeds (^falce v, sern. 
Tonco) are used in colics on account of their aromatic qualities, now 
ascertained to be the same as those residing in Asperula odorata and 
Antlioxantlium cdoratum. 
Sasafras {Ocotea Cymharnm^ H. B, and K. Syn. i. 459. "Arbor 
gigantese magnitudinis, sub nomine Sauafras Orinovensibus celebrata, 
ligno durissimo suaveolente, ad fabricaudam scaphas inserviente." A 
decoction of the bark is recommended in nervous diseases, and as a 
powerful sudorific. 
Sauco {Sambucns Canadensis, L.). Samhncns Mexicana^ Presl, I 
think, is not a good species, but rather a form of S. Canadensis^ the 
younger leaves being slightly pubescent, and the glands not always 
present. This Elder is far from being as efficacious or sudorific as iS', 
nigra^ which is sold by our druggists. 
Sauce {Salix Ilumboldliana, W. Griseb. 113.) A most graceful 
tree J growing like Populuspyramidalis, and much employed for making 
living fences about Caracas. The bark is astringent, but not much 
used.
