if only l)y one letter, must 1)C eonsidered as distinet names. Callistachys 

 Vent. (1803) and CaUistachya liaf. (1808) must therefore be considered 

 as distinct and valid geuerie names. Sir James Edward Smith used 

 CaUistachya in the same year as Rafinesque but whether earlier or 

 later I cannot say; but that is immaterial as it is a pure synonym of 

 Callistachys, Vent., and, therefore, even if it antidates the use of the 

 name of Rafinesque, the latter under Article 50 is valid. The species 

 is of wide distribution, being found in Europe and Asia as well as in 

 North America and has received many specific names. Two other 

 forms may be worth recording here. One from Dahuria has blue 

 flowers and very broad leaves and may be known as CaUistachya Vir- 

 ginica (Lin.) Raf. Var. Sibirica (Lin.) N. Comb. Veronica Sihirica Lin. 

 Sp. PI. Ed. 1, 12, 1762. The other has purple flowers and is from Vir- 

 ginia according to Pursh and others and may be known as CaUistachya 

 Virginica (Lin.) Raf. Var. purpurea (Raf.) N. comb. Eustachya purpurea 

 Raf. Am. Month. :\Iagaz. 190, 1819; Leptandra Virginica (Lin.) Nutt 

 Var. purpurea Ph. in Eaton & Wright N. Am. Bot. Ed. 8, 297, 1840. 



Plantago lanceolata, Lin. 



This is a very variable species but four well defined forms are recog- 

 nizable. One with linear or linear-lanceolate, 3-5-ribbed, thinly hirsute 

 blades, 3-5 inches long by 5 lines wide, on marginless petioles nearly or 

 quite of their own length which together are about f the length of the 

 scape. Spikes oblong or nearly ovate. This apparently is the Lin- 

 nea type. Another form is much taller and more robust, scapes about 

 20 inches long. The leaves are elliptical or oblong-lanceolate, over a 

 foot in length by If inches in width, tapering into short winged petioles 

 which with the blades are more or less boat-shaped; the blades are 7- 

 nerved and cross-wrinkled; spikes cylindrical; this probably is Var. 

 contorta, Guss. (P. lanceolata var. altissima Dene.) A third form is 

 somewhat similar but has smaller leaves (six inches or so long), not 

 cross-wrinkled, and with the margined petioles fiat; this appears to be 

 var. irrigua, Dene. A fourth form is found in sand or rocky grounds, 

 and is not over 10 inches in height with 3-ribbed sessile or subsessile 

 acute or accuminate leaves two or three inches long and not over 3 

 lines wide, generally densely hirsute; spikes short, ovate or sub-globular; 

 this probably is Var. eriophylla, Webb. I have collected the forms 

 from various places as follows:
