Preliminary conservation status assessment.
This species has an Extent of Occurrence (EOO) of 312,285.154 km 2 and an Area of Occupancy (AOO) of 44.000 km 2 and is assessed as Least Concern (LC) following IUCN (2022).
Notes.
Strobilanthes erecta resembles S. phyllocephala J. R. I. Wood & Scotland in the shape of its leaf base, but it differs in having ovate-elliptic or obovate and caducous bracts. Wood and Scotland (2006) treated S. laotica as a synonym of S. dimorphotricha subsp. rex, but after investigation of type specimens we found that this species is conspecific with S. erecta. This is corresponded with the report of Son et al. (2018).
Son et al. (2018) proposed the duplicate of Put 3302 from K (without barcode) as the lectotype of S. suborbicularis. Unfortunately, we have not seen this duplicate. Moreover, they also provided a picture of the lectotype, but we found that this picture is the sheet BM 000906322 at BM, not K: the citation of K may therefore be in error. We were able to locate five duplicates of Put 3302 one deposited at each of ABD [ABDUH: 2 / 914], BK [257647], BM [BM 000906322], C [C 10005219] and KYO.
