Notes. – The holotype is a collection folder of two sheets, of which the barcoded one has the locality, date, and collection number handwritten, and the other has a printed label.

It was the only material studied by Boissier and, therefore, there was no need to lectotypify the name as done by Al-Shehbaz in MOAZZENI et al. (2018: 253).
