Secondly, because it is fairly typical of the general arrnagement of the long tuberous roots, and Thirdly, because in addition to the two new roots or incipient tubers one usually finds at the base of the new bud, at, or about flowering time, we here have four, , to the bud on the left-hand side of the flowering stem. The central root, it will be seen, is much thicker, and longer than the other three, two of which are on either side of it, whilst the tip of the third is just visible at the back of and above the bud. This is the first instance of its kind, not only in this species, but also in Spiranthes Romanzoffiana and S. cernua that I have found a plant with four new roots developed at flowering time, although, as pointed out in my paper "Further Notes on the Underground Development of S. Romanzoffiana and S. cernua", in "The Orchid Review", vol. XXXII, 1924, pp. 296-300 and plate, these two species, especially when on dry ground—-which latifolia favours— have been found in the spring to have developed a second, and in one extreme case, a third pair of roots, presumably as extra reservoirs to draw upon in case of drought. While the present example may be taken as fairly typical of the disposition of the long roots, there are of course many devia- tions, nor does one generally find two new buds at the base of each flowering stem, one being perhaps,
