hairs are found upon only one of the two surfaces. In Alstrcemem, the 

 leaves, owing to some unknown cause, are always resupinate ; that is to 

 say, in consequence of a twist of their petiole, that side which is born 

 uppermost is turned undermost. Now, it is very curious that the surface, 

 which, under other circumstances, would have no breathing-pores, no hairs, 

 and not elevated veins, acquires all these characters in consequence of 

 having to perform functions that are foreign to it ; while the other surface, 

 in like manner, loses them."

This is an interesting species, and seems prolific in flowers. The spathes 

 have a broad white membranaceous margin. The flowers are starry, almost 

 as large as a shilling, of a full deep yellow ; but each of the six segments has 

 a deep blood-red spot near its base, and the three inner segments have also 

 a large horseshoe-shaped spot or cloud of the sfime hue at the tip, occupy- 

 ing the segment's whole width. It is nearly allied to S. ^raminifblium, but 

 is sufficiently distinct. (Bot. Mag., Nov.)

Messrs. Loddiges " raised this from seeds sent by Mr. Cuming. It grew 

 to the height of nearly .3 ft., and flowered in the green-house in April and 

 May. It should be potted in light loam; and is likely to be nearly or quite 

 hardy with us. It increases itself by offsets from the roots. (Bot. Cab., 

 Nov.) The figure much reminds us of S. striatum.

 yellow, margined with red. Young plants may be obtained by dividing the 

 creeping stem, when the pseudo-bulbs wUl establish for themselves an inde-

The genus Cirrhge'a differs from all the genera in the tribe VandecB by 

 its stigma occupying the apex, and not the face, of the column; while its 

 anther is situated at the back. In this last respect it agrees with Notjlia, 

 which is, however, otherwise distinct. C. Loddigesii grows tolerably well 

 in vegetable mould, if placed where the air is humid and the drainage com- 

 plete; and, in such situations, flowers in August. Professor Lindley also 

 refers to this genus the Gong6r« viridi-purpiirea of Hooker; and describes 

 a third species, specimens and a picture of which exist in Dr. Hooker's 

 herbarium, and names it C. fusco-liitea. As, however, this is probably not 

 yet in the country, we must at jiresent only tabulate the second.

Probably this species exists in no^British collection but that of the Hor- 

 ticultural Society, and that of the Rev, and Hon. W. Herbert. It is 

 " perhaps, the smallest of all the species of Oncidiuni properly so called! 

 The truncated callosity of the crest, with a sort of two-horned screen at its 

 back, and the two lateral erect lobes of the lip at its side, are, when viewed 

 in profile, not very unlike a bull's head in miniature." {Bot. Beg., Nov.)
