(From Engler and Prantl.) show a very close similarity to what is seen in the Selago group, but with gradually increasing definition of the strobilus from the lower vegetative region. In the Phlegmaria group, which includes about eighteen species of epiphytic character, the spikes are slender, and dichotomously forked, with sporophylls as a rule very different in size from the foliage leaves (Fig. 142). Occasionally sporangia may be found in the vegetative region.
