ORCHIDACE^ 115 



lection, which was distributed as no. 191 of Lindheimer's Texan 

 plants, and find that two among them agree with the type speci- 

 men and with the description published in the Journal of the 

 Boston Society of Natural History. The description is as follows : 

 " radice fasciculata ; caule foliato ; foliis linearibus, superioribus 

 sensim minoribus vaginantibus lanceolato-subulatis ; sepalis petalis- 

 que basi cohaerentibus oblongo-linearibus, laterahbus angustioribus 

 labellum reflexum crenulatum apice non dilatatum aequantibus vel 

 superantibus." 



In the Bulletin of the Torrey Botanical Club 25: 610 (1898), 

 Dr. J. K. Small published the description of a new Spiranthes as 

 GyrostacJmjs Reverchoni, and interpreted it as a homologue of >S'. 

 hrevifolia, Chapman, differing from that species in its longer, more 

 numerous leaves and in the rhombic-ovate lip. The type material 

 was collected on prairies at Lancaster, Dallas Co., Texas, in June, 

 by Julien Reverchon. After an examination of the type material 

 in the herbarium of the New York Botanical Garden, and of speci- 

 mens in the Gray Herbarium, in the National Herbarium, in the 

 herbarium of the Missouri Botanic Garden, and in the posses- 

 sion of Mr. Reverchon, it seems to me that this species is identical 

 with the northern Spiranthes which has passed as S. gramiiiea, 

 var. Walteri, Gray, and as S. i^rcecox, Watson, and is conspecifie 

 with S. vernalis, agreeing with it in the conformation of the lip 

 and in every detail of taxonomic value. The plants collected by 

 Mr. Reverchon are taller than any I have seen from New Eno-- 

 land, measuring Q5 cm. in height, but in other respects are the 

 same. 



In Dr. Britton's Manual of the Flora of the Northern States 

 and Canada, issued in 1901, Dr. P. A. Rydberg described as 

 a new species Gyrostachys linearis. The type specimen com- 

 prises four plants, collected by C. F. Austin near Closter, Bergen 

 Co., N. J., slender in habit, with narrow leaves, dense, short pu- 

 bescence, and with lips more or less ovate-oblong in outline. 

 This material is at once distinct from Sjnratithes 2^Tcecox, Wat- 

 son, through the dense pubescence of the axis of the inflores- 

 cence and the pubescence and shape of the lip, and agrees well
