Notes. – There is a single collection folder in G-BOIS with four sheets. One sheet, which is barcoded, was collected by Boissier in April 1846 and has a label with the locality in Boissier’s handwriting (Fig. 34, p. 126). The remaining three sheets are unlabeled, and their fruit maturity is much more similar to the lectotype rather than to the syntype G00332661.

Another specimen was also collected by Boissier in March 1846, but with a printed label annotated by Boissier, it is listed above as a syntype.
