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.

1. Although nucleic acid could not be extracted from Nostoc, all of its constituent radicles, viz. phosphate, pentose, adenine, guanine, cytosine and uracil, were extracted in quantities sufficient to allow of identification. 2. This supports the view that chromatin, a substance of nucleo-protein nature, occurs in the cyanophycean cell, which contains no definite nucleus. 3. The writer suggests tentatively that in the absence of a highly organised nucleus delimited by a membrane, the nuclear materials may more readily diffuse out of the cell and exert a growth-promoting effect on neighbouring plants. This suggestion is supported by the fact that other enucleate organisms, as Saccharomyces and Azotobacter, which contain nucleic acid or its derivatives, show a marked growth-promoting effect on the green plant.
