6 JOURNAL OF THE ARNOLD ARBORETUM [vol. iv. 



Meth. in. 65 [1813]) identical with /. prinoides Aiton of Michaux's Flora 

 (n. 22!)), a synonym of /. deeidua Walt. 



10. Azalea fulva is apparently A. calendulacca var. a flammea of Mi- 

 chaux's Flora (i. 151) which has been referred by me (in Wilson & Rehder, 



Monog. Azaleas, 131 [1921]) to Rhododendron speciosum (see also I.e., 

 foot-note 2). 



11. Azalea pilosa is Menzicsia Smithii of Michaux's Flora for which the 

 correct name is Menzicsia pilosa Jussieu. 



12. Ipomoea erecta. This is apparently the plant described in Michaux's 

 Flora (i. 142) as Tpomopsis elegans and now referred to the genus Gilia 

 as G. rubra Hell. (G. coronojrifolia Pers.). The name does not appear in 

 Index Kewensis where only /. erecta R. Br. is cited; R. Brown's name will 

 not be invalidated by the earlier homonym, as the latter is a synonym of 

 the still earlier Polemomium rubrum L. which is now r Gilia rubra Heller. 



13. Mussaenda frondosa is an earlier name for Pinckneya pubens of 

 Michaux's Flora (i. 105), but the name is not valid as there is an older 

 Mussaenda frondosa of Linnaeus. Mussaenda frondosa Michaux is not 

 cited in Index Kewensis nor is it mentioned as a synonym of Pinkneya 

 pubens in Sargent's Silva or in the North American Flora. 



14. Vaccinium ciliatum. This is the oldest name for V. erythrocarpum 

 of Michaux's Flora (i. 227) but as there exists the older valid name V. 

 ciliatum Thunberg, V. erythrocarpum will stand. Vaccinium ciliatum 

 Michaux is not in Index Kewensis and is not mentioned in Gray's Synop- 

 tical Flora. 



15. Lapathum occidentale is without doubt Cliftonia monophylla Britton. 

 Lapathum is a Tournefortian genus referred by Linnaeus to Rumex, but 

 Tournefort's Lapathum orientate with which Michaux compares our species 

 is Atraphaxis frutescens K. Koch (Polygonum frutescens Linnaeus). The 

 similarity of the fruit w r hich has given rise to the vernacular name "Buck- 

 wheat-tree" for Cliftonia apparently led Michaux to refer our plant to the 

 same genus as Lapathum orientate which he had observed in Persia. The 

 name Lapathum occidentale is not mentioned in Index Kewensis and the 

 plant is not described in Michaux's Flora. 



* Lauras indica is apparently the Lauras Catesbyana of Michaux's 

 Flora (i. 244) now Ocotea Catesbyana Sargent, while the glabrous variety 

 found in Carolina of Laurus borbonia which Michaux says is often er- 

 roneously called L. indica is the Laurus carolinensis of his Flora (i. 245) 

 now referred to Persca borbonia Sprengel. 



16. Rhododendron minus is R. minus of Michaux's Flora (i. 258) and 

 is the oldest name for R. punctutum Andrews as stated by me in 1912 

 (Rhodora, xiv. 100). 



17. Kalmia hirsuia is K. hirsuta Walter of Michaux's Flora (i. 257). 



18. Kalmia ... is apparently the A", cuneata of Michaux's Flora 

 (i. 257). 



1!). Andromeda polifolia is apparently A. glaucophylla Link, as lVlichaux 

 gives the mountains of Pennsylvania as the habitat of the species; in his
