VERBASCUM. 231 
1. Versascum Linn. Maullein. 
* Leaves strongly decurrent. 
1. V. Thapsus (L.?); 1. ovate-oblong crenate densely woolly 
on both sides all decurrent, st. simple, spike dense, pedicels 
shorter than the calyx, cor. rotate, segments oblong obtuse, 
filaments woolly, 2 longer nearly glabrous, anth. all nearly equal. 
—E. B. 549. V. Schrader Koch.—St. 4—5 feet high. Fl. about 
twice as long as the calyx. Filaments with white wool, the 2 
glabrous ones about 4 times as long as their slightly decurrent 
anthers.—Waste ground. B. VII. VIII. Great Mullein. 
2. V. thapsiforme (Schr.); “1. decurrent crenulate woolly, 
upper ones acuminate, racemes spiked, segments of the cor. un- 
equal obovate, 2 of the anth. oblong.” Fries Fl. much larger 
than those of V. Thapsus, about 4 times as long as the calyx. 
‘The 2 glabrous filaments scarcely twice as long as their greatl 
decurrent anthers.” Koch.—Kent. Hudson. B. VII. VIII. E. 
** Leaves not decurrent, flowers in clusters. 
+ Flowers yellow, hairs on the filaments white. 
3. V. Lychnitis (L.); 1. crenate nearly glabrous above woolly 
and powdery beneath, lower 1. elliptic-oblong wedgeshaped below 
scarcely stalked, upper 1. sessile ovate-acuminate with a rounded 
base, st. angular panicled above with ascending branches, stam. 
equal, filaments all with white hairs.—E. B. 58.—-Fl. on short 
stalks, small, numerous, cream-coloured.—Road-sides and waste 
places. B. VIL—VII. White Mullein. E. 
4. V. floccosum (W. and K.); 2. obscurely crenate clothed with 
mealy deciduous wool on both sides, lower 1. oblong-elliptical at- 
tenuated into a stalk, upper l. sessile acuminate, st. terete panicled 
above with patent branches, stam. nearly equal scarlet with white 
hairs.—V. pulverulentum Sm., E. B. 487.—Fl. on very short 
stalks, which, as well as the calyx, are densely covered with wool, 
bright yellow. Cal.-teeth often glabrous.—[In V. pulverulentum 
(Vill.), of which Schreber saw authentic specimens, the stem-l. are 
subsessile ovate-oblong rather acute unequally and doubly ser- 
rate, the upper surface of all the leaves only slightly woolly, the 
wool is not deciduous as in our plant, and the st. and branches 
are angular. |—Road-sides in Norf. and Suff.; and Den of Cullen, 
Scotland. B. VII. Hoary Mullein. E. Ss. 
+t Flowers yellow, hairs on the filaments purple. 
5. V. nigrum (L.); 1. doubly crenate nearly glabrous above 
subpubescent beneath, lower 1. cordate or ovate-oblong with long 
stalks, upper 1. cordate-ovate nearly sessile, st. angular, raceme
