Among the plants of the Clafs Syzgezefia, there are fome few whofe feeds are not furnifhed with any pappus, 
or down, as the Lap/ana communis, and Rhagadiolus of Linn avs; in the prefent plant the feeds in the outer row 
are deftitute of pappus, or crowned only with a few very fhort briftles, while all the others are furnifhed in the - 
ufual manner. Haver, the firft author, perhaps, who noticed this appearance, confiders it of fufficient 
confequence to found a genus on; he therefore makes it a Rhagadiolus, a genus alfo of TounNEzrOoRrTS, 
united by Linn aus with the Lap/ana. 
Lzzns has very minutely noticed the characters in which this plant differs from the 4:/pidum of Linn aus, 
whofe fpecific defcriptions of the two plants are not fufficiently difcriminating; the feta, as Lzzrs has obferved, 
and we have found by experience, varying greatly in both fpecies, for /etis fimplicibus, we would therefore fub- 
flitute calycibus glabriufculis, feminibus exterioribus pappo  deffitutzs, either of which chara&ers will diftinguifh 
them; the old Botanifts diftinCtion of radice praemoría is not to be depended on in all cafes, as it varies with . 
the age of the plant. 
When we figured in the 53d number of the Flora Lond. the Leontodon hifpidum, we had no idea that the 
prefent plant was a diftin& fpecies, prefuming too much on the charaéter drawn from the nodding of the 
peduncle, which we had found highly ufeful in afcertaining that fpecies; we confidered it as a variety merely, 
arifing from fituation, and fuch fhould probably ever have regarded it, had not the fingular circumftances 
attending the outer row of feeds been mentioned to us by a Botanift of fuperior difcernment, Dr. Benjamin 
Dawson, Minifter of Burgh, in Suffo/& ; on examination we found the feeds exaétly as he had reprefented 
them, and on comparing the two plants, found them to differ in a variety of particulars, the moft ftriking of 
which we {hall here enumerate. 
The whole plant is much fmaller, the leaves fpread more on the ground, and are of a darker colour, the 
flower-ftalks are more numerous, lefs upright, not only turning down or nodding at top, but frequently irregularly 
curled, efpecially in the young ones, befet with long crooked hairs, particularly towards the bottom, never 
furnifhed with fmall fquamz or leaves, the flower-buds, and flowers themfelves much fmaller in proportion to 
thofe of the di/pidum, more refembling thofe of the Leontodon autumnale, the uppermoft leaves of the calyx 
fmooth, and at the point and edges of a deep purple or blackifh colour; and that as far as we have obferved 
invariably, many other characters might be pointed out; but thefe it is prefumed, affifted by the figure, will 
be fufficient to make the plant known ; in doubtful cafes recourfe may be had to the feed, and it will not be 
neceffary to wait till that be ripe; the character appertaining to it will be vifible on a nice examination, even 
when the plant is in flower: we may add, that the two plants cultivated in the fame foil and fituation, continue 
widely different. 
Prefuming that an Englifh name for this fpecies, drawn from a circumftance leading fo immediately to 
a knowledge of the plant, would be fuperior to a literal tranflation of the name of Air/utum, and which 1s fo 
very fimilar to that of 27/prdum, we have been induced to give it that of deficzent. 
The Leontodon birtum is frequent on moft of the heaths and commons about town, particularly Hampftead- 
Heath, and Barnes-Common, where it flowers from June to Auguft. 
We rarely meet with the hirtum and hifpidum on the fame fpot.
