Postscript to Tab. 7310. Tnx conocarpa. 
When making, under the description of the above-named 
plant, some observations on the synonymy of its congener, 
I. paraguensis, it had escaped my memory that. Mr. N. H. 
Brown, in an important essay on the Paraguay Tea plants, 
publisbed in the Kew Bulletin (for 1892, p. 133) had 
proved that the I. paraguayensis, Tab. 3992 of this Maga- 
zine, is a species of Hlzodendron, probably EH. quadrangula- 
tum, Reiss. (in Mart. FI. Bras. vol. xi, p. 33, t. 5, f. 1, 2); 
and that the figure of J. paraguayensis in Hooker’s Journal 
of Botany, vol. i. (1842), t. 3, is I. nigropunctata, Miers 
(I. affinis, var. angustifolia, Reiss. l.c. p. 70, t. 14, f. 9). 
Of the other species for which I have cited the Flora 
Brasiliensis as yielding a Maté, Mr. Brown regards 
I. sorbilis, I. domestica and I. theezans aS varieties of I. 
paraguensis.
