species
Lepidium obtusatum
Although the exact meaning of the species “obtusatum” was not given by Kirk (1891) it seems that he took the name from the shape of the hypogynous glands (i.e. the nectaries) which he specifically noted (Kirk 1899) are “very short and obtuse”.
Holotype: New Zealand: Port Nicholson, n.d., Miss Kirk, WELT SP030109! Notes: Kirk’s protologue for L. obtusatum states “Hab. North Island: Maritime rocks at the entrance to Port Nicholson, Miss Kirk” (Kirk 1892). Only one herbarium sheet annotated 'Lepidium obtusatum n.s., Port Nicholson, Miss Kirk' and so matching the protologue as to name, collector (Miss [Lily] Kirk), type locality, and labelled in the naming authors hand could be located in the WELT (the main herbarium where Kirk material has come to be lodged) so this sheet is regarded here as the holotype.
