This plant is allied to A. gladiifolium, Thou. The rhizome is 

 about a foot long, rather slender, with numerous thick, fleshy, blunt 

 leaves from | to nearly 1 inch in length. The pale green flowers, 

 rather smaller than those of A. gladiifolium, Thou., are solitary in 

 the axils of the upper leaves on very slender pedicels ^ an inch 

 in length. The petals and lateral sepals, which are narrow and 

 fleshy, are apparently not patent, but carried forward horizontally. 

 The lip is | an inch in length ; it has two small erect lateral lobes, 

 the median one being long and beak-like, quite cylindrical for the 

 greater part of its length, and tapering to a point. Between the 

 lateral lobes is a depression, which gradually fades away in the 

 median lobe. The spur is long and horizontal, a little dilated 

 wbere it joins the lip ; and the end is clavate and slightly up- 

 curved. The ovary is about | an inch in length. 



Aeranthus Curnowianus, Reichenb. fil. Gard. Chron. 1883, ii. 

 p. 306, a plant recently introduced into cultivation from Mada- 

 gascar, would belong to the genus Angrcecum as defined by the 

 authors of the ' Genera Plantarum.' I have not seen it.
