Cryptostegia grandiflora (Apocyneæ)
This is a very straight climber moves slowly Reverse of Watch: several internodes projected obliquely beyond stick & then put in perpendicular stick which was slowly wound round.— Five internodes clasped it; but a basal one may not have acted, & the young one (counted in the five) at summit, which was only 1 1/2 in inch in length did not act.— A thread tied to near tip was spirally wound round shoot, in direction reverse of that in which must would have been ⸮⸮ twisted — It is like with garter, giving a reverse twist with finger, each time garter was wound round. —
Now all have 4 or 3 lower internodes power of movement? or are they sensitive to stick??
Is third wound more than once?
