 Azores, Bellis azorica, has been separated 

 from the others by Mr. Watson under the 

 above generic name, mainly on account of

 of conical receptacle of the flower-head. 

 The leaves are like those of the common 

 daisy in form, but the heads are smaller, 

 audit has hranching stems. It is named 

 after Dr. M. Seubert, author of a Flora of 

 the Azores. [A. A. B.]

SHEADENDRON. A name given by 

 Bertolini to a tree of which specimens were 

 sent to him from Mozambique as the 

 Butter-tree of the natives. It has since 

 been shown by Klotzsch that this tree, 

 with two other allied species or varieties 

 from the same country, belong to theorder 

 Combretacece, and indeed only differ from 

 Combretum itself by the unimportant cha- 

 racter of the fruit being four-angled in- 

 stead of four-winged ; they will therefore 

 probably be considered as species of Com- 

 bretum. It is still however far from being 

 proved that either of them is really the 

 tree called Shea by the natives, as furnish- 

 ing the fatty substance which has been 

 compared with butter, more especially as 

 the tree so designated in other parts of 

 Tropical Africa is known to belong to a 

 totally different natural order.
