Note 8 — Chapter I

E. Lehmann (Bull. l'Herb. Boissier, Ser. 2, VIII, 1908, p. 229) has published an admirable paper on the interrelationships of these species and has instituted cultural experiments which will probably much elucidate the nature of their specific distinctness. As regards the existence of intermediate forms he comes to the conclusion that two only can be so regarded. The first was described by Kuntze from specimens found on a flower-pot on board a Caspian steamer, from which Lehmann proposes the new specific name Siaretensis. This comes between polita and filiformis, a close ally of Tournefortii. The other, which combines some of the features of both polita and Tournefortii, was found in the province of Asterabad.
