plant was distributed as 1. cardiosepala Hochst. in Herb. on. itin. 

 1841, nos. 207, 384, and published by Choisy (DC. Prod. ix. 129), 

 and this— its first name under // •„ -i o ! I in my judgment 

 stand, leaving I. calycina for Mei.ssner's plant. But if, following 

 Dr. Hallier, calycina Clarke is to be retained, the Brazilian plant 

 will require a new name, and may be called I. Meissneki. 



The retention of cardiosepala (Hochst.) will, however, necessitate 

 another change, for Meissner has described a Brazilian plant (I. c. 

 265) under that name: this may be called I. cordatosepala. 

 " I. cariosepala Klotz. in Nub. PL," given by Mr. Clarke (FL 

 Br. Ind. iv. 201), is a composite misprint for "I. cardiosepala 

 Hochst. in Kotsch. Iter nubicum." 



Mr. Hemsley, in the 'Index Fl. Sinensis' (Journ. Linn. Soc. 

 xxvi. 160), is of my opinion with regard to the retention of calycina 

 for the Brazilian plant, but, for some reason which I cannot fathom, 

 gives Meissner's cardiosepala precedence over Hochstetter's, and pro- 

 poses a new name for the latter — I. Hardwickii. The synonymy of 

 the plants is as follows : — 



I. cardiosepala Hochst. Un. it. 1841, nos. 207, 384 ; Choisy in 

 DC. Prod. ix. 129 (1845). 

 /. calycina Benth. ex C. B. Clarke in Fl. Brit. Ind. iv. 201 



(1883), non Meissn. 

 I. Hardwickii Hemsl. in Journ. Linn. Soc. xxvi. 160 (1890). 



I. CORDATOSEPALA. 



I. cardiosepala Meissn. in FL Bras. vii. 265, non Hochst. 



Dr. lialher would, I presume, maintain Meissner's cardiosepala 

 and reduce his calycina. Into the labyrinth to which " once a 

 synonym always a synonym" would lead, I have no desire to 



Ipomoea aubiculata Hallier. — Dr. Hallier sets aside Choisy's 

 name /. Cordofana in favour of the above, because it was dis- 

 tributed under the name of "Batatas aunculata Hochst." No 

 description was appended to this, and it seems to me an arbitrary 

 proceeding to reject a name, duly published with complete 

 description in its right genus, in favour of a nomen nudum given to 

 a plant in a genus which is not retained. 



Ipomoea setifera Poir. — Dr. Hallier queries Sierra Leone for 

 this species : we have a specimen from that locality from Afzelius. 



Ipomoea zambesiaca mihi (Journ. Bot. March, 1894, 85), non 

 Baker (Bull. Miscell. Inform. Feb. 1894, 70).— I regret that in 

 proposing this name for L acuminata Baker, non Roem. & Schultes, 

 I overlooked its previous employment for another species. I pro- 

 pose to substitute for it I. Hallebiana, in commemoration of the 

 botanist who has added so much to our knowledge of African 



° Ipomoea sagittata VeaL—Convolvulus Wheleri Vahl. Symb. ii. 

 36, is correctly referred by Choisy (DC. Prod. ix. 372) to this 

 species, but, as he does not seem to have seen the type, it may be 

 well to place the matter beyond dispute. Plukenet (Phytographia, 

 lxxxv. fig. 3 1 calls it Convolvulus sagittariqfoliis, fiore purpurea
