A sp. of Clerodendrum..?

… the third photograph confuses me. Does it belong to the same plant?. Leaves seem to be alternate, an unusual combination with such flowers.

… is right Verbenaceae has rare plants which shows alternate leaf arrangement!!! the last photo of leaves are not of this plant.

it is Clerodendron calamitosum L. Mant. 90, 1767; Cl. in Hook.f., Fl. Brit. India 4:591, 1883; Cooke, Fl. Pres. Bombay 2: 513, 1958 (Repr.); Singh et al,Fl. Mah. St. 2: 702, 2001; Yadav & Sardesai, Fl. Kolhapur Dist. 371, 2002; Almeida, Fl. Mah. 4: 111, 2003.
Synonyms: Volkamaria alternifolia Burm.f., Fl. Ind. 137, 1768.
