This s'^ecies is evidently allied to '•^. derressum an 'j. frpgr?=ns, 

 it leaves being somewhat like those of G. depressum, but less spreed- 

 ina:, and it differs from both snecies by having pedicellate flowers. 

 The calyT is very much smaller thm that of G, fra grans, and I sus- 

 nect also than that of ^. denressum, but the latter I have not seen. 

 It is stated, however, not to exr>and its flowers except in bright 

 sunshine, while I find the flowers of G-. suave will ex^^end in a very 

 dim light, for after taking the plant into a room to describe, I 

 left it there all night, vrith its flov/ers tightly closed, and v/as 

 astonished to find the corolla v/idely exnanded in the morning bet- 

 vreen 8 and 9 am,, while the room was very dimly illuiainated, (teylight 

 being excluded bv a Venetian Blind and side curtains and the morning 

 sunless and cloudy. I left the nlant in the room ell that day (at 

 the e'^d of J'^nuary) , and at night excluded as much light as I could 

 by means of the blind and curtains, the corolla then having its 

 petals tightly tv.'isted together up to their middle, v;ith the tips 

 spreading. The next morning, about 9 a.m., before the blind was 

 drawn up, the corolla was widely expanded and fragrant, the room 

 being very dimly illuminated, this mornine: also being sunless end 

 very gloomy, and the temperature below 60° Fah. I have now (Sept. 

 28, 192?) repeated the above eErerim_ent with the same result, ^-^ow 

 do these and other plants know when it is time to open their flowers'? 

 For in the case of this species it seems evident that it is not 

 strong light or sunshine that causes it to exnand its f lov/ers , but 

 that it is influenced in some mysterious v-ay by the time of the day. 

 Yet certain other species of this genus will only expand their 

 flov/ers in bright sunshine, and not at all on a dull day, and even on 

 sunny days '-ill not fully open them unless the temnerature is 70 

 Fehr. or higher.
