SELECTED ARTICLES. 
botanically unknown, I examined it carefully, and found that 
it belonged to the Linnaean class and order, Pentandria Mono- 
gynia, to the natural order Violariese, and tribe Violeae, of De- 
candolle, and to the genus Ionidium of Ventenat; but, after 
comparing its botanical characters with those of the several 
species of this genus that are described by the numerous mo- 
dern authors, to whose works I have had access, and more 
particularly to the excellent Prodromus systematis naturalis 
Regni Vegetabilis, by Decandolle, I could not discover any 
species among them to which the plant from Riobamba could 
with propriety be referred, though it most nearly resembled 
Ionidium parviflorum. It appears therefore, to be a new spe- 
cies; and as it has been the practice with botanists to permit 
those, who make known the characters of genera or species 
that have not previously been described, to bestow on their 
plants such names as they may consider appropriate, I hope 
that the same favour may be extended to me in regard to the 
Cuichunchulli; and in this case I would propose that its speci- 
fic designation should be Ionidium Marcucci, as a compliment 
due to Monsieur Marcucci, for the zeal and patience with which 
he encountered innumerable hardships and dangers in its search, 
and, when he had succeeded in obtaining it, for his philan- 
thropic endeavours, through my means, to have its reputed 
medicinal properties ascertained, and to give the fullest publi- 
city to its localities and peculiar characters, so that all hereaf- 
ter, who might want it, should know where to procure it, and 
how with certainty to recognise it. The following are its bo- 
tanical characters: 
Ionidium Marcucci (nobis.) Ionidium Marcucci. 
Calyx quinque-partitus, basi in Calyx five-parted, running et base 
pedunculum decurrens, persistens ; into the peduncle, persistent; the 
sepalis ovatis, acutis, glabris, mar- sepals ovate, acute, smooth, mem- 
gine membranaceis, duobus inferi- branaceous at the margin, the two 
oribus reliqua paulo superantibus. inferior (as they are termed by Ven- 
tenat and Decandolle,) longer than 
the rest.
