to forty per cent of the plants have the flowers in a one-ranked spike, as in S. 

 graal/s. As regards the twisting of the spike there is every gradation from the 

 straight spike to the extreme twisted or corkscrew form. As a rule the one- 

 ranked spikes are more twisted than the three-ranked ones, and the corkscrew 

 form occurs principally in many-flowered one-ranked spikes, the degree of twist be- 

 ing about in proportion to the number of flowers. In large and vigorous plants 

 the one-ranked arrangement is as frequent as in small ones, though less evident 

 at first glance on account of the crowding of the flowers. No difference in the 

 flowers themselves ha yet been observed to accompany the different arrange- 

 ments of the inflorescence.

*i2 Goodyera. 



This genus is now undergoing revision. Plants hitherto known as G. repens 

 are more than likely to be the variety opkioides or the species tesselata. Observa- 

 tions will be in order.

*i3 Habeiiaria blepliariglottls, Torr. 



The single station of this species in Manl:hester has been, unhappily, too well 

 known, and the plants are now nearly if not quite exterminated. 



*i4 Habeiiaria fimbriata, R. Br.- 



Abundant in the vicinity of Manchester. The study of its forms is extremely 

 interesting. There are two well marked forms which are so constant in their dif- 

 ferences as to demand a special account. What may be called typical fimbriata 

 begins to bloom about the ist of June. The flowers are scentless, except for the 

 rank odor common to the orchid family, and are gone by the ist of July. S'oon 

 after July ist the other- form begins to flowei", some plants being found in flower 

 as late as August 25th. In this form the flowers are richly scented, having a fra- 

 grance similar to that of H. psycodes, but less heavy. The lip and petals are deeply 

 cut, sometimes almost as much as in H. lacera, the pedicels are more slen'der than 

 in the early form and the whole plant has a more delicate and graceful aspect. 

 There are two abundant stations of this late form known. In one of them the 

 flowers vary in shade from pinkish to rather dark purple ; in the other, besides 

 the plants with light and dark purple flowers, there are always some with pure 

 white flowers. 



The differences may be summarized thus: Early forn^, June ist to July ist, 

 flowers purple, not fragrant, rather stoutly pedicelled, with lip and petals not deep- 

 ly cut; late form, July ist to August 25th, flower dark to light purple, pinkish or 

 pure white, very fragrant, with rather slen'der i^edicels and with lip and petals 

 -deeply cut.
