without doubt that C. Delessertiana and C. parabolica 
are identical. 
An earlier name, C. Mutisti var. 8. published by Lam- 
bert (Ill. Cinch. (1821) 9) may be referable to C. para- 
bolica, but this is impossible to confirm without an exam- 
ination of the type. No mention is made by Lambert of 
the collector of his specimen, but, like C. parabolica, it 
was probably collected by Juan Tafalla. Lambert’s de- 
scription is too brief for critical comparison with C. para- 
bolica, but he does include in his diagnosis certain of the 
important features of this species: 
‘foliis. ... subtus ramulisque valde pilosis, margine un- 
dulatis subrevolutis, panicula brachiata valde pilosa... .”’ 
and also under var. B. .. . folits ovalibus obtusis basi ro- 
tundatis subcordatisve.”’ 
In 1849, Weddell took up Lambert’s species, C. Mu- 
tisii, listing var. B. as var. crispa, but in 1869, Weddell, 
combining this variety with C. parabolica, transferred 
both entities to synonymy under another binomial of 
Pavon’s, C. rugosa, a species from Cuenca, also published 
by Howard. A summary of the tentative synonymy of 
this cinchona and an expanded description based on re- 
cent collections follow :
