30-A G. King and D. Prain — Descriptions of some New Plants [No. 2, 



T. cuspidatum Bl., and curiously enough this happens to be much the 

 rarest of the five that are to be found within the limits of the Gardens. 

 We have been unable to find it noted that the otherwise excellent figure 

 which Blume gives of T. cuspidatum makes the curious mistake of revers- 

 ing the position of the lower pistillodia. These are C} r mbiform organs 

 with the concavity directed upwards in the natural state ; in Blume's 

 figure the concavity is made to look downwards. 



Before leaving this subject it may be pointed out that though 

 Roxburgh has cited Loureiro's Arum trilobatum as equivalent to his 

 A . orixense, this is by no means clearly the case. The pistillodia of 

 A. orixense (the true A. trilobatum) are, as Roxburgh describes them, 

 yellow ; those of A. trilobatum Loureiro, are described, on the other 

 hand, as red. The truth is that the genus Typhonium requires more 

 careful and extended study, from living plants, than it has yet received.
