N*ar ildrdn-rii nmJtiJiora Makixo ; but (jffers from it in ihe leaves with very prominent 

 Aeins and viirilets underneath, nnd in the glabrous connectives. 



As I was ijiformeil by Mr. Duxx, this int»-rtsting ijlant ha.l iirst been cliscovered iu Hong- 

 Ivong in 19:0, a yenr before I colUcttcl the s.-.me spccies in the same island. It is very so c]o«e 

 to the Japancse species G. mvllifiora that it was nssumicl to be id. n'ical vvitb the latter. After 

 coming back home, I have compartd the plaut Miih thj lype of (J. muUijiora iind found that 

 the Hongkong pl.tnt is a little diflferjnt from the Jnpanese in the leaves which are very obtase 

 or rormd at the base, and have very prominent veins and veinle's undernenth. lu G. muUiJiora, 

 tLe lciives are very cuneiite at the bas;; and ha\e vtry s'endtr sc.ircely pruminent veins ancl 

 veinlets nnderneath. The le.avcs of the mw sptcies ai-e cp.ite lrs'eil< « a- d iridfscent d.trk 

 green .above, very p-ale beneatb. 



lu referring this pLmt to Gardhvria, I have followtd Ekhdei; (Fl. Wils i 504) .and h.ave 

 ret.ained the genus in the oldor and wider sense, .as the char.acter on which Ea. " .~i "-^ki reliecl 

 to separate Pseudoriardneria f rom Uardneria is not (»nst.ant ; for G. lanre 'luta, as pointed out 

 Toy REHDEii, has Ihe fl^wers jast intermedi.ate between the Iwo genera.
