the drape is 3 lin. diam., with a prominent mammiform and 

 obsoletely 4-lobed stigma. In another specimen the leaves are 

 more polished, extremely smooth above, the margin showing a 

 disposition to become toothed ; they are pale brown above and 

 fuscous brown beneath, the petiole being thinner and 3-carinated 

 below*.

This is a still more distinct species, with lanceolate leaves, 

 which are cuneate and entire for two-thirds of their length, their 

 summit being shortly attenuated and emarginated ; above, they 

 are opake and very smooth, almost nerveless, with a reddish flat 

 midrib ; they are pale green, somewhat paler and yellowish be- 

 low, where their delicate nervures are scarcely prominent, and 

 their midrib, of an orange-red colour, is not much raised. They 

 are 2^-2| inches long, f inch broad, on a petiole 4 lines long. 

 The specimen has neither flower nor fruit. In form the leaves 

 somewhat resemble those of I. nigropunctata, but they want the 

 peculiar dotted glands so conspicuous in that species f.
