Wight's Herb. No. 942 named M. indicum Willd. consisted really of M. interme- 

 dium DC. and M. tiiberculat'um Boxb. mixed together. The single plate we have 

 illustrating Indian Myriophylhim viz. Wight HI. 1. 102 is made up of a stem of M. in- 

 termedAum together with an analysis of the fruit (very good) of M. tuberonlatum. 



Further, the plate otBaloragis oliganiha Wight Ic. t. 1061 is M. intermedium DC.,' 

 as are Wight's own herbarium specimens of his Haloragis oligantha; but not so 

 Amott's, as see under 8erpicula zeylanica above. 



lastly, though Wight's Herb. 942 was named M. indicum, Willd., Wight's own 

 Herb. No. 1094 is truly M. indicum as Amott quotes it to be in JT. ^ A. Prodr. 339.
