﻿herbarium." I have identified this specimen, but am not so sure 

 that it is " the one described by Forster." It must be remembered 

 that Forster did not claim his 1. cornea as a new species ; his 

 diagnosis is tbat of I. earned Jacq. (with which he incorrectly 

 identified it) cited from Murray's Systema VcjrtnhUium, ed. xiv. 

 His new species have " F." appended to the diagnosis. ■ jjillebrand 

 (Fl. Haw. Isl. 316) cites "I. Forsteri Gray, Bot. U.'S.E. Exp. 

 ined." as a name for this plant, and retains it as a distinct species, 

 although he says it is "probably not distinct from /. denticulata." 



I. gracilis Br. is, as Bentham (I. c.) points out, so different in its 

 aspect that it' seems to me better to follow him in keeping it 

 distinct, although, as he says, " it is difficult to assign any positive 



(I.e.) "is evidently a very different plant, probably closely allied 

 to, if not identical with, L ,mif»rmis." Mr. C. B. Clarke (Fl. Brit. 

 Ind. iv. 208) also maintains the distinctness of I. littoralis Bl., 

 though both authors agree in placing the plant so called by 

 Thwaites (Enum. 211) as a synonym of/, denticulate. 



Ipomoea Clappertoni Br. in Denh. & Clapperton, Travels, 240 

 (1826). — I do not find this taken up by Hallier. It is maintained 

 by Choisy (who erroneously refers to it I. incurva Don), but Brown's 

 type -specimens show that it is, as he suspected might be the case, 

 /. aquatica Forsk. The locality should read, according to Oudney's 

 note on our specimens, " Matuma," not " Tintuma," as printed in 

 the Travels. Besides some of those cited by Hallier, we have 

 African specimens of I. aquatica from Angola. Welu-it^l, t;i71 !

 is a remarkable plant, with inflated stems about half-an-inch thick: 

 this he named in MS. Convolvulus Nymphasa, and added a note, of 

 which the following is a translation :—" Roots on the soil, the 

 upper part floating on the surface of the water, like a Nymphaea : 

 the stem is hollow, and sends small swimming roots into the water." 



Ipomoea stolonifera J. F. Gmel. Syst. 345 (1796).— On the 

 principles of the Index Kewensis, this is the name to be maintained 

 for I. on-nosa Br. Prod. 485 (1810), to which Mr. Jackson reduces 

 it as a synonym. Dr. Hallier, following Boissier (Fl. Or. iv. 112) 

 prefers to call the plant I. littoralis, as it was the Convolvulus 

 littoralis of Linnaeus; but if, as seems probable (see above), 

 I. litt<>r«Jis of Blume is to be maintained, a further readjustment of 

 names will become necessary. With this must be placed /. hum Hi*

Ipomoea calycina.— Mr. C. B. Clarke (Fl. Br. Ind. iv. 201) gives 

 this name to Aniseia calycina Chois., and Dr. Hallier retains it, as 

 being the oldest specific name ; but calycina had been applied by 

 Meissner (Fl. Bras. vii. 260 (1869) ) to a Brasilian species. The
