Topographically they can be divided into the following groups: prickles, bristles, intermediate hairs, large hairs, largest hairs, marginal hairs. On the basis of dimensions they fall into four groups. The total number of hairs is somewhat variable. The mean for males is 122.65 hairs on one lobe; for females, 128.82 hairs. The interpseudotracheal papillae vary both in position and number. The mean for males is 65.9 papillae; for females, 67.65. The labial nerve divides, in the labellum, into four principal branches which consist of proximal processes of the sense cells of all hairs and interpseudotracheal papillae. Preparations stained by methylene blue revealed numerous multipolar cells. It was impossible to decide with certainty whether they are nerve cells, perilemma cells, or tracheal cells. They did not stain with silver. Numerous free endings revealed in preparations by use of Kenyon's method appeared to be the finest tracheoles seen on preparations stained by the method of Romanes.Read More
