Flowers sessile; calyx divided nearly to the base into 5 lanceolate up to 5 mm long, acuminate lobes, hirsute outside; corolla 7–8 mm long, 5-lobed, outside hispid, inside villous, the throat hairy.

Note — Wong (1989) reduced L. pseudo­lucidus to L. curtisii . Lasianthus pseudo­lucidus is very closely related to L. curtisii in having calyx almost the same as the latter. However, it has narrower leaves, which is a little different from the typical L. curtisii .
