Stephen Robson (1741–1779) and his nephew Edward Robson (1763–1813) were both Quaker botanists who lived in Darlington, County Durham. Stephen is best known for his British Flora published in 1777, and Edward had a considerable reputation as a particularly competent botanist. Some confusion seems to exist regarding the authorship of a rare plant list for Durham, Plantae rariores agro Dunelmensi indigenae, attributed to Stephen Robson in most recent bibliographical literature. This paper re-examines the evidence for the authorship of this list and suggests that although Stephen Robson produced a short list of local plants the longer and more critical list, Plantae rariores … was compiled by his more knowledgeable nephew Edward.

A New Species

Silene lulakabadensis Heidari, F. Ghahrem. & Assadi is described as a new species from Zanjan Province, Iran. The new species is a dark green plant, perennial and woody at the base, that was collected on marl soil slopes at 2100 m. It is believed to be closely related to S. eriocalycina Boiss. from section Auriculatae (Boiss.) Schischk. but is a smaller plant, with much shorter internodes, and pinkish-white retuse to emarginate petals with very small or no scales. It is a very rare plant and its conservation status is assessed as Critically Endangered.
