What reading level is Organography of Plants, Especially of the Archegoniata And Spermaphyta Pt. 1 book?
To quickly assess the difficulty of the text, read a short excerpt:
* Darwin, Variation of animals and plants under domestication.
* Lowe makes the remarkable statement regarding ferns — 'Spores gathered from an abnormal portion of a frond can reproduce this abnormality, whilst spores from a normal portion of the tame frond can produce normal planU.' See his ' Fern-growing,' p. 26. Other authors contest this.
* Regarding this and other cases see Godron, Des races v^g^tales qui doivent lenr origine i nne monstruosite. Nancy, 1875 (Extract from the M^moires de TA...cad^mie de Stanislaus, 1873).
ETIOLOGY OF MALFORMATIONS 185 according to Hunger*, who has observed that when the plants are cultivated in pots these vegetative shoots are suppressed. This however may be the case only when the pot-plants are grown under unfavourable conditions. In viviparous plants of Poa alpina, which I have grown in pots for four years, the vegetative shoots have always appeared. Hunger's observation however is quite in conformity with the facts which have been cited above with regard to reversion to the juvenile form* The formation of flowers must be considered phylogenetically as the older, the buds as having arisen somewhat later ; both ' tendencies ' are obviously connected with different external conditions, and the plants which produce flowers only are * reversions' to the original type.
