It would appear immediately after second paragraph 19, differing from E. Pusillum and E. Reniforme in having the basal leaves hirsute, not white-lanate, beneath. In second paragraph 13 of the key the words (except in E. Parishiif' should be inserted after Leaves. This species was known previously only from southern California and Baja California.

Excerpt from Leaflets of Western Botany, Vol. 8 It is rather obvious that the two plants are at least moderately interfertile, and therefore there is some question whether or not they should be maintained as separate specific entities. When viewed from the standpoint of geographic range and morpho logical differences (tomentose leaves and 5 - 7 Stamens as com pared with non-tomentose leaves and 8 to 10 stamens) it seems not inconsistent to continue to maintain columbianum and L. Groenlandicum under separate specific entities. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Now available in an affordable softcover edition, this classic in Springer's acclaimed Virtual Laboratory series is the first comprehensive account of the computer simulation of plant development. 150 illustrations, one third of them in colour, vividly demonstrate the spectacular results of the algorithms used to model plant shapes and developmental processes. The latest in computer-generated images allow us to look at plants growing, self-replicating, responding to external factors and even mutating, without becoming entangled in the underlying mathematical formulae involved. The authors place particular emphasis on Lindenmayer systems - a notion conceived by one of the authors, Aristid Lindenmayer, and internationally recognised for its exceptional elegance in modelling biological phenomena. Nonetheless, the two authors take great care to present a survey of alternative methods for plant modelling.
