. Comparative anatomy of the vegetative organs of the phanerogams and ferns;. Plant anatomy; Ferns. 94 CELLULAR TISSUE. since hitherto the observers, with the exception of Hanstein, have treated the objects as exceptional, and have not thoroughly considered the points of structure in question. As examples of glandular hair-structures, which may here be described rather more in detail than above, we may begin with the bladder-like hairs, and cite once more those of Cistus creticus. The flat leaf of this shrub is grey with numerous branched hairs, and, especially at the base, with long pointed unicellular erect appressed hairs. It bears also short, multicellular hairs, which are capitate and glandular above ; and lastly, numerous spindle-shaped large glandular hairs, which consist of a lower broader part composed of many disc-shaped cells, and a thin cylindrical, 1-4 celled terminal part (Fig. 36). The glandular structure occurs on the slightly widened apex, and often in places on the lateral wall of the terminal part. Besides the examples of capitate glandular hairs and villi, and the scales connected with them already men- tioned, may be named those figured by Weiss from the calyx of Maurandia semperflorens (/. c, Fig. 279) and Antirrhinum majus (, Fig. 310), and by Hanstein from the leaf-buds of Ribes (/. c. Fig. 30-33), Syringa (Fig. 68, 69), Helianthus annuus (Fig. 91, 92). The adjoining figure (Fig. 37) represents a glandular villus from the petiole of Conoclinium atropur-.
