The synonymy is discussed by Merrill 1. c. Rheede, Hort. Malab. 
II, t. 56, mentions pubescent petioles, as does Desrousseaux in his 
description of Convolvulus tiliefolius, which shows that this is the 
plant intended, though the venation, of the leaves in the plate, looks 
like that of Ipomcea campanulata Trim., while the depth of the 
sinus is varied by Rheede’s artist. ‘Trimen’s description of I. cam- 
panulata Trim. is partly taken from a specimen of this plant collected 
by Thwaites. Prain (Journ. As. Soc. Beng. LXIII, p. 107) states that 
A gyreia tiliefolia is purely a sea shore species.
