Notes.

Emberger (1936) cited a locality in the protologue of Celsia longirostris var. antiatlantica : "A A:in praeruptis siliceis montis Kest supra Imdrighis, 15oo m ubi maio floret", but he did not indicate in which herbarium the specimen(s) were deposited. We have traced six specimens which agree with the protologue and from which to select the lectotype: Four preserved at herb. RAB (RAB030634, RAB030632, RAB030633, RAB030635) and two from Herb; MPU (MPU006100, MPU006101). The sheet RAB030634 kept at Herb. RAB is chosen here as the lectotype of this variety.
