This is a plant the general structure of whose leaf is similar 
to that figured at Tan. XV. of this work. (J. eppendiculata), 
but which comes from a very different part of the world, and is 
characterized by the undivided larger lobes of the leaf, never cut 
into pinne-like divisions, and the quadrate and simply emargi- 
nate apex of the stipules. It is besides considerably smaller 5 
and at first sight its general habit resembles starved specimens 
of J. sphagnoides, so much so that the learned botanist to whom 
we are indebted for its discovery had actually marked it in his 
MSS. as the same species,
