terminal cones, by no means freely produced, are very small and 

 abortive. New for Scotland ; but probably overlooked.

A NEW CHIMAPHILA FEOM SAN DOMINGO. 



By Sidney F. Blake, A.M. 



While working recently on the variations of the widely dis- 

 tributed Winter green known as Chwia2:)hila umbellata (h.) Burt., ■■'• 

 I was struck by the marked difference from all other specimens 

 in the British Museum shown by those collected in San Domingo 

 by Baron Tiirckheim, and referred on the label to this species. 

 Although the plant has long been known to range over a large 

 part of temperate Europe and Asia, nearly all of North America 

 from Canada to the mountains of Mexico and Guatemala, and 

 Japan, its presence in the West Indies has only recently been 

 indicated by Urban (Symb. Antill. v. 453 (1908)), on the basis of 

 specimens collected long ago by Eggers ; but a careful examination 

 of Tiirckheim 's specimens, which are in fresh flower, and of 

 duplicates at Kew of Eggers' plant, which is in old fruit, shows 

 that they represent a decidedly distinct species. Not only are 

 the leaves much smaller and fewer-toothed, but the peduncle and 

 pedicels, densely dotted with glandular atoms in all the forms of 

 G. livihellata, are here perfectly glabrous, while the filaments, 

 widened and short ciliate near the middle in G. umbellata, in the 

 San Domingo plant are enlarged nearer the base and are quite 

 glabrous. In view of these marked characters the San Domingo 

 plant seems best considered an endemic species which may bear 

 the name / 



-: Chimaphila domingensis. Planta humilis 10-15 cm. alta ; 

 foliis cuneato-obovatis obtusiusculis subsessilibus 1-8-2-5 cm. 

 longis 6'5-8 mm. latis dentibus 2-5-jugis hebetibus ; pedunculis 

 (et pediculis) glaberrimis 4-6 cm. longis ; floribus 3-5 subumbel- 

 latis ca. 11 mm. latis ; sepalis orbicularibus glaberrimis margine 

 minute eroso non ciliato ; petalis suborbicularibus minute irregu- 

 lariter erosis (purpureis fide Eggers (apud Urban), sed in specim. 

 Tiirckheimianis certissime albidis) ; antheris violaceis ; filamentis 

 basi ovate ampliatis glaberrimis.

I am indebted to Dr. Eendle for permission to dissect a flower 

 from the Tiirckheim specimens in the British Museum. ^^ 



* This combination has been universally quoted from Nutt. Gen. i. 247 

 (1818), but can hardly be considered made there, as no synonym is cited; 

 however, it had been properly made the previous year by Barton (Veg. Mat. 

 Med. U.S. i. t. 17, t. 1 (1817) ), as indicated by Gray, Syn. Fl. U.S. (1818).
