TAXONOMIC NOTES

Delphinium reverdattoanum and D. barlykense Lomon. & Khanm. are morphologically similar. However, they can be distinguished by the characteristics of stem hairiness, ovary and follicle texture, and staminode limb morphology. Delphinium reverdattoanum features stems that are pubescent with a mix of simple and glandular hairs, glabrous ovaries and follicles, and a deeply emarginate staminode limb. In contrast, D. barlykense has glabrous stems, pilose ovaries and follicles, and a staminode limb that is crenate or shallowly emarginate at the tip ( Friesen 2003).
