different, althougli Vatkc and we differ consideraLly in a few cases. 

 Thus the "whole of the Coraposittc of tho 1862-3 distribution of 

 Schimper are assigned by Vatke to 141 species, comprised in G2 genera, 

 while we should place the same material in 144 species, comprised in 

 63 genera. The following are the principal discrepancies that I have 

 detected between Vatke's determinations and our ow^n : — 



Vehnonia POLYMOKi'UA, Vatke. Under this name Vatkc treats of 

 four forms : a. adoensis ( V. adoensis, Schultz Bip., :== V. niacroccphala, 

 A. Rich.), jS. AMBiGUA ( V. Kotschyana, Schultz liip.), y. acckue.vs, and 

 S. jriCKocEi'nALA ( V. alyssinica, JSchultz Bip., ^= I'eichostomiua frutico- 

 sum, 11. Br.). Each of these forms of Vatke we regard as a di&tiuct 

 species. 



The plant (no. 1530) which Vatkc calls Veunonia iitmenolepis, 

 A. Hick. " / " seems to us quite different from the specimens of tliis 

 species authentically named in the Kew herbarium ; we have described 

 it under a new name of our own. 



Vernonia LEoroLDi, (ScIiuUz Bip.), Vatke, and V. Bu'Ontini, Vatke, 

 we regard as together forming one species. 



Vernonia (Cyanoims) flagellaris, Vatke, is the same as V. urticce- 

 folia, A. liich., the type-specimens of which we have seen. 



We agree in uniting Conyza SciiiMPERr, Schultz Bip., to the Indian 

 plant C. stricta, Willd., and we add to the same C. macroruiza, Schultz 

 Bip., which Vatke keeps distinct; though we do not associate with 

 these the plant numbered 238, which is a Conyza, but which we do 

 not identify with any described species. 



The specimens (no. 294 and no. 436) which Vatke refers to Conyza 

 abyssinica, Schultz Bip., we had referred to two different species, ouo 

 (no. 294) to G. Ilochstettcri, Schultz Bip., and the other (no. 436) to 

 C. pxjrrhopappa, Schultz Bip. ; but the species of Conyza arc critical 

 and exceedingly difficult to discriminate. 



Under the name of Conyza HocnsxETTEui (Schultz Bip.), Vatke 

 treats of four forms : a. agrestis (C. Hochstctteri, Schultz Bip.), (i. 

 PEATEKSis, y. SYLn^STRis, and 5. MONTANA (C varicgata, Schultz Bip.). 

 We regard each of Schultz's species as good, and Vatke's forms ^. and 

 5. we combine to form a new species. 



Blumea Bovei, Vatke, founded on the Conyza Bovei, DC, and 

 being the B. ahyssi^iica, Schultz Bip., we prefer to call by the last- 

 mentioned name ; at all events, the specific name of De Caudolle has 

 been referred to Blumea by Bentham and Hooker, Gen. PL ii., 1:90. 



Laggeka UETEROMALLA, F«^Z;e, is a spccics of i?m/« ; and we identify 

 it specifically with /. Mannii, Benth. & Hook, f., that is, Vernonia (J) 

 Mannii, Hook. f. 



The plant (no. 1349) which Vatkc refers to Sru-EUANxnus angusti- 

 FOLius, I)C., differs from it by solitary hermaphrodite florets ; it is the 

 Oliyolepis anyustifolia, Steetz. 



GNAPnALiusr aueictjlatum, a. Rich. The specimen (no. 1441) 

 which Vatke thus names we refer to G. Pctitianum, A. llich. ; we 

 have seen authentic types of both species, which, however, certainly 

 lie very close together. 



GNArnALiuM UL1GIN0SU5I, L. The specimen (no. 68) we refer to 

 G. Unionis, Schultz Bip., which appears to us to be distinct from G. 

 uliginosum, L., by the white scarious tips of itb involucral bmcts.
