Morphology Reproductive morphology Inflorescences
Inflorescence terminal and axillary, composed of several lax, narrow raceme branches, forming a panicle, pubescent to tomentose on axis; cymes with peduncle up to 25 mm long, lax or dense, 8 - 15-flowered; bracts ovate or ovate- lanceolate, adaxially glabrescent, pubescent or sparsely villous, abaxially densely villous; bracteoles linear, linear-oblong or linear-oblanceolate, 1 - 2 mm long, villous, caducous or persistent; pedicels 1 - 3 mm long at anthesis, 3 - 10 mm long in fruit, sparsely villous

Note
This species is very similar to Isodon lophanthoides, and the two species are often confused in herbaria. In the wild, I. hispidus is a larger and more pubescent taxon, although the types (Wall. Cat. 2741) are less hairy than some specimens. Li (1988) reduced Rabdosia shimizuana Murata to a synonym of Isodon hispidus stating that it is identical to I. hispidus according to Murata's description. However, from the photograph of the holotype R. shimizuana has the leaves congested near the stem base, and therefore resembles several specimens of I. lophanthoides from various parts of Thailand and Indo-China. It is clear that R. shimizuana is actually just a form of I. lophanthoides, which Muschler (1907) recognised as P. volkensianus Musch. and Doan (1936) recognised as P. striatus var. kerrii Doan (nom. inval.).
