Gardner's n. 11, from Rio Janeiro, is the true 5. carpini- 

 Jblia, Cav., a very common plant in Rio collections ; the 

 S. carpinoides^ DC, which I have from the same district, and 

 also from Madeira, communicated by Dr Leman, under the 

 name of S. carpinifolia, and from continental botanic gardens 

 under the names of S. carpinifolia, and S. uhnifolia, is readily 

 known by the form of the carpels, with a spur on the inner 

 edge besides the two points on the back.
