Excerpt from The Kansas University Quarterly, 1901, Vol. 10: Series A; Science and Mathematics The interneural bodies referred to in the introduction occur on some specimens of each species and variety of Taem'opfen's in the collection. They are small, oval, resistant bodies, situated be tween the veins, half immersed in the epidermis of the frond, nearly globular in shape, some smooth on top, but more often showing a slit across the top or side very suggestive of the slit for the discharge of spores in many eusporangiate ferns. The slit, apparently, has no regular position on the bodies; it is sometimes across the top, sometimes on the side, sometimes parallel to the direction of the veins, or again transverse to the veins. The bodies, when removed from the epidermis leave a cup-shaped cavity. In many of the cavities there is a cast of the slit, indicat ing that many of the bodies had the break turned down, and doubtless many of those appearing smooth on top are slit below. Some of the however, are certainly not slit in the manner described. One specimen of T. Newberrr'ana having many of the bodies preserved, has none showing the slit, and when te moved and mounted they are seen to be round and entire. If we accept the hypothesis that the bodies in question are sporangia, the absence of the cleft in this specimen would naturally find its explanation in the supposition that the sporangia are not yet mature.
