 Nat. Ord. CAPEIEOLIACE^. 

 Besides the many well-known points of close affinity between 

 CaprifoliacecB and Buhiacece, an examination of the Indian plants 

 of the former Order enables us to add one which has generally 

 been supposed to present a good distinguishing character between 

 them, namely the large stipules present in two genuine species of 

 Lonicera itself. In Samhucus the leaves are sometimes described 

 as stipulate, an appearance due in the Indian species to a pair of 

 reduced basal pinnules. 



The structure of the ovules in this Order is similar in many 

 respects to that of Cornece, and is the same as in many Mubiacece. 

 These, in the very earliest stage of Viburnum Tinus, consist of a 

 minute mamillary curved nucleus encircled with an annulus, which 

 is the only integument ; this annulus is no further developed, but 

 as the ovule grows to maturity, it continues unchanged at its 

 apex. The fully-developed ovule hence has no apparent inte- 

 guments ; that represented by the annulus, being the one which 

 answers to the inner (secundine) in more highly-developed ovules,
