Tufts of hairs, such as are present in Corallorhiza and many other Orchids, are absent: but communication is kept up with the soil by occasional hyphae which traverse the superficial cells. According to. l-iG. 154- Seed of Neottia infected by fungus, and showing the first stages of germination. (After Bernard.) ( x 100.) age and position the fungal filaments show various stages of disorganisation. In some cells only the indigestible remnants of the hyphae remain. The nuclei of the digesting cells meanwhile increase in size, and starch appears in quantity.
