LECTOTYPIFICATION In the protologue Griffith (1854) cited “HAB. Assam . In umbrosis humidis collis humilis prope Gubroo Purbut : March , 1836.”, but did not provide specimen details. We have traced a single sheet at K with three flowering twigs and two barcode numbers ( K000858010 , K000858011 ). In the upper part of the sheet, there are two flowering twigs and the barcode number is labelled in between them. Thus , we are considering them as a single collection under the barcode number K000858010 . K000858011 has a single flowering specimen but the collection details are not clearly readable. On the other hand, the collection K000858010 has a field label annotated ‘ Gubroo Hills , 3.8/36’. The location exactly matches with the protologue while the date of collection is presumably March 8 1836 . Further, the sub-opposite or alternate, oblong-ovate leaves, acuminate at apex, petaloid calyx and five-winged flower buds in K000858010 agrees with the protologue, hence, it is selected here as the lectotype .
