the existence of a deltoid Botrychium, and glance slightly at its 
history. 
1. Ray, &c. 
“TLunariam minorem ramosam, & Lunariam min. fol. dissectis 
Westmorland. D. Lawson hujus plante varietates esse ; non distinc- 
tas species opinatur. (D. Doody Syn. II. App. 340. Lunariam 
minorem foliis dissectis revera distinctam speciem vult, cum seg-’ 
menta seu lunule non solum eminenter sint secte, sed planta etiain 
elatior sit & botrus racemosior. Est Lunaria botrytis minor pin- 
nulis laciniatis. in Borealibus nostris Pluk. Alm. 288. Mr. Doody 
received it from Sir Th Willughby, but hath since seen it several 
times gathered by our Herb-women).”—Razi Syn. 129. 
From this passage I draw the following conclusions :— 
Ist. That Ray supposed there were two British species of Botry- 
chium distinct from lunaria. 
2nd. That Mr. Lawson thought them both varieties of lunaria. 
ord. That Dillenius believed one of them, described as with /oliis 
dissectis, to be a distinct species. 
4th. That this species, or supposed species, was found by or known 
to Ray, Lawson, Doody, Willughby, and the herb-women. 
2. SWARTZ. 
In his ‘ Synopsis Filicum,’ dated 1806, Swartz describes a new spe- 
cies of European Botrychium, under name of Botrychium rutaceum. 
“ B. frondibus subsolitariis bipinnatis, pinnis ovatis, incisis.” —Syn. 
Fil. 171. 
He cites “ Breyn. Cent. t. 94,” as representing his plant. 
8. WILLDENOW. 
In his ‘ Species Plantarum,’ dated 1810, Willdenow also describes a 
Botrychium rutaceum. 
““B. scapo superne unifrondoso, fronde bipinnatifida laciniis emar- 
ginato- bi- seu tridentatis obtusis. W.” 
He cites Mor. Hist. iii. p. 594, sec. 14, t. 5, f. 2, 3, as representing 
his plant. © 
Side by side with Botrychium rutaceum, Willdenow describes a 
second species; and this was also known to the pre-Linnean bota- 
nists. This second species is called B. matricarioides; and from 
Willdenow’s days downwards the two names have been almost inex- 
tricably involved.
