ON THE OCCURRENCE OF STIPULES IN ILEX AQUIFOLIUM. 467 



with hyaline bacillary spores growing at the apex. This appa- 

 rently new species of Cercospora has been called Cercospora cof- 

 feicola, Berk. & Cooke. Nearly all the species of this genus occur 

 on living or fading leaves, and many of them grow on discoloured 

 spots. The septate threads generally grow in tufts ; and the 

 habit is somewhat that of a small Cladosporium, to which the genus 

 is closely allied. It is noteworthy that we have here, in another 

 locality, an entirely different species, genus, and order of Fungi 

 growing upon almost identical pallid spots on coffee-leaves. It 

 renders still more difficult an answer to the question, " What is 

 the cause of this form of coffee-disease ? "

In the ' Flora of British India,' i. p. 598, Sir J. D. Hooker 

 observes that the character attributed to the Ilicinae requires 

 considerable alteration. In the revised ordinal character he 

 writes— " Leaves exstipulate, or with minute stipules ; " and he 

 gives small stipules to the species Ilex Godajam. Dr. Brandis 

 also, in his ' Forest Flora of North-west India,' attributes stipules 

 to two of his species of Hex. 



The occurrence of stipules in the order Ilicinae is not there- 

 fore quite novel, though I cannot find that the presence of 

 small stipules in Ilex Aquifolium has hitherto been noticed. 

 Indeed, in several of our works on systematic botany, it is ex- 

 pressly stated that the natural order Ilicinae has "exstipulate
