24 DB. H. F. HANCB's SUPPLEMENT TO 



somewhat broader at the base and quite simple racemes, I can de- 

 tect no difference ; and the leaves of the Japanese plantare sgrne- 

 what variable, and the racemes not always branched. Moreover 

 S. IcmcifoUa grows on the White- Cloud Hills above Canton. 



21. Paxechites Bo-wringii, Hance in Seem. Jaum. Bot. vi. 299. 

 Grathered by Mr. J. C. Bowring in Hongkong, and not known 



from elsewhere. By an error ofS^he printer in omitting the numeral 

 4 before pollicaribits in the diagnosis, I am made to describe the 

 foUicles as only 1 iach instead of 4 inches long, as is really the 

 case. 



•Parechites Thunbergii, A. Gray in Mem. Amer. Acad. vi. 402. (= 

 Rhynchospermum jasminoides, lAndl. ; Beath. Fl. Hongk. 221.) 

 The seeds both of the preceding, as described by me, and of 

 this, as observed by Miquel (Ann. Mus. Bot. Lugd.-Bat. ii. 130) 

 and Oliver (Joum. Linn. Soc. ix. 166), having a sessUe coma, it is 

 clear that neither is a JRhjnchosperimm, ; besides which, as I 

 pointed out when describing my P. adnascens, A. DeCq,ndolle'8 

 genus Bhynchospenmmi was published eighteen years later than 

 that of Keinwardt, and cannot stand. Nor is this affected by 

 the identity of this latter — suspected by Miquel and established 

 by Oliver — with Lessing's Leptocoma, over which Eeinwardt's 

 genus has five or six years' priority. 



*Buddleia. 



B. asiatica. Lour., and B. Neemda, Ham., according to the ob- 

 servations of Mr. Sampson and myself, preserve in Southern China 

 their characters quite clearly, and show no disposition to run 

 together. The latter is by far the more common of the two ; and 

 its flowers exhale a most powerful scent of honey, which I do not 

 think is the case vdth the other plant. 



22. Ipomoea panictilata, R. Br. ; Benth. Fl. Austr. iv. 414. 



In woods and thickets, but not very common. Diffused 

 throughout the tropics of the whole world. The seeds have a 

 large dense tuft of dirty white wool springing from the apex, 

 longer than themselves, and enveloping them in the fruit ; but 

 the rest of the surface is smooth. In the specimens examined 

 by me I have always found the ovary simply 2-celled, without 

 spurioufl septa as in Batatas ; but Dr. Wight figures it (Madras 

 Joum. of Lit. and Sc. v. t. 11) as completely 4-celled. Prof. 

 Grisebach (Fl. Br. W. Ind. 469) refers this to the obscure 

 J. digitata, L.
