It is not only the general appearance of the plant we 

 figure and describe to-day that has led us to consider it 

 the type , of a new genus. There are other far more weighty 

 reasons. On its arrival at M. Linden's establishment , it was 

 referred by our predecessor, Lemaire, to Disteganthus , but 

 it soon became evident that it could only enter this genus 

 through the species named D. Scarlatinus, Hort. Lind. In- 

 deed it differs too widely from the lateral inflorescence of 

 D. basilateralis. Lemaire, to say nothing of the totally diffe- 

 rent habit , and blue not yellow flowers, not to strike us at 

 once. If we had the flowers of D. scarlatinus before us wc 

 might have determined whether they presented any further 

 differences, or whether it possesses the dextrorse wing of 

 the calyx-lobes, and the horny funicular prolongation of the 

 chalaza that characterise our new genus, meanwhile Ave 

 were unable to admit the generic identity of the two plants. 



After having taken the opinioi

 • At first sight, L. Hoofjemh.rpii might ea>ilv be mistaken 

 for L. Jenkinsii of Griffith, but in addition to the difference 

 in habitat, the former in Sara and the latter in Assam . an 

 examination revealed the following distinctions in L. Jen- 

 kinsii: petiole less deeply furrowed, more spreading at the 

 base, and less abruptly narrowed, spines closer together, 

 slanting, very sinuous, having a much shorter basal swelling 

 or tubercle, alternating with another series of much smaller 

 tubercles; petiole olive green, not reddish, at the base; 

 limb more completely orbicular with a very acute almost 

 closed sinus, plaits not collected in phalanges of 5 to 7, 

 but all free and spreading , broader and divided about one 

 third or half through the blade of the adult leaf.
