ft Corolla rotate and star-like, or broadly cup- shaped, 

 with or without a raised rim (annulus) on the disc or 

 base of the cup, sometimes forming a short tube for 

 the corona, but with no distinct campanulate tube. 

 The base of the sinuses between the corolla-lobes 

 produced into triangular teeth ; outer corona sessile 

 on, and adnate to, the base of the corolla. 9. Hu-

 88 Outer corona cup-shaped, or the segments very 

 deeply divided into two subulate lobes, and more 

 or less adnate at the base to the staminal tube or 

 base of the inner coronal segments so as to form 

 a small pouch at the base, rarely quite free to the 

 base. 2. Caralluma E. Br. (See also Stapelia 

 intermedia.) 

 888 Outer corona in one piece, disc-like, pentagonal,

[Now that the serial issue of this Index is approaching com- 

 pletion, we take the opportunity of announcing that we propose to 

 issue it in a separate form. Our plan has somewhat extended itself 

 as the work has proceeded, and no one can be more fully aware 

 than we are ourselves of the numerous imperfections in our records, 

 especially in the early part of the alphabet. We hope, therefore, 

 that everyone who can will kindly send us any corrections or 

 additions they may have noted as to what has already appeared, as 

 well as any information as to names not as yet reached. We pro- 

 pose bringing the work as completely as we can down to date at 

 the end of the present year, and issuing it early in 1891, bound in 

 cloth, at 3s. 6</. per copy, to subscribers whose names are received 

 before publication, the published price being 6s. Intending sub- 

 scribers should send their names, but not the amount of subscription, 

 to the Editor of this Journal, care of the Publishers, 54, Hatton 

 Garden, E.C. Due notice will be given when the volume is ready 

 for distribution.]
