QUIINACEAE 
Quiina leptoclade Tu/asne in Ann. Sci. Nat., ser. 3, 11 (1849) 159. 
COLOMBIA: Comisaria del Vaupes, Rio Apaporis, Jinogojé. ‘‘Small tree. Fruit 
orange. Makuna name = na-mor-so-roo. Maku name = teg-ee-doo.'’ June 
15, 1952. R. E. Schultes et I. Cabrera 16730. 
A snuff of the dried leaves of this tree is employed to stop 
recurrent nose bleeds, apparently a common ailment amongst 
the Maku Indians. Little is known of the chemistry of the genus 
Quiina (Gibbs loc. cit. 3 (1974) 1371, 1388). 
MARCGRAVIACEAE 
Souroubea crassipetala de Roon in Acta Bot. Neerl. 18 (1969) 
701. 
COLOMBIA: Comisaria del Vaupés, Rio Apaporis, Raudal Yayacopi (La 
Playa) and vicinity. ‘‘Epiphytic vine. Flowers dark red, yellow at centres.”’ 
February 16, 1952. R. E. Schultes et I. Cabrera 15401. — Same locality. 
‘‘Epiphytic vine. Flowers maroon and orange; fruit red-orange.’’ August 18, 
1952. R. E. Schultes et I. Cabrera 16912. 
A mouth wash of the leaves of this vine is prepared for treating 
‘*sores of the mouth’’ — various irritations of the mucous mem- 
brane which may have a variety of causes. 
Little is known of the chemistry of the Marcgraviaceae. Tan- 
nins are high in some species (Gibbs, loc. cit. 3 (1974) 1371), 
explaining possibly this native use which may be based on 
astringency. The presence of resin cells in some species of 
Souroubea might likewise justify this use. 
Souroubea guianensis Aublet var. cylindrica Wittmack in Mar- 
tius, Fl. Bras. 12, Pt. 1 (1878) 253.
