The Caucalis Anthrifcus approaches fo near to the 77/7/2 already figured, as fometimes to occafion fome little 
difficulty in difünguifhing the two : this difficulty did not efcape the obfervation of RAv, who with uncommon 
accuracy has pointed out the peculiarities of each in his Hf. Plant. which we fhall place before our readers, 
nearly in his own words.—* ft, The Anthrifcus is the taller plant, growing to the height of two. cubits (three 
* feet); the zufe/fa, more dwarf, fcarcely ever exceeds a foot, or one cubit at fartheft. 2dly, The Anrhrifeus 
* ig more upright, with longer internodes; the 77/2/z, with a more crooked flalk, has more numerous joints. 
* gdly, The ftalk of the Anzhrifcus 1s more hirfute near the ground than that of the zfefa. — 4thly, The florets 
* ofthe Anrhrifeus, which are white, or of a pale red colour, have petals nearly equal in fize, with purple 
* anther; the florets of the 7z/z//z are white, verging to yellow; the two outermoft petals are very manifeltly - 
.*- Jarger than the reft, and the anthere white. 5thly, The feeds of the :nfe/fa are by far the largeft, and the 
* little tips on the crown of the feed green; thofe of the Anhri/cus are more fragrant, more aromatic, and of 
* a duller colour with purple tips. Laftly, The Anthrifcus is feldom found but in hedges and among bufhes, 
* while the 77/z//z is never found in hedges, but for the moft part among corn.” 
Thefe diftinGtions, as far as we have obferved, are perfe&tly juft, and worthy of their author; we fhall only 
obferve in addition, that when we have been at a lok for a diftin&ion, the moft ready one has been afforded 
by the prefence of the involucrum, from which Mr. Hupsow has judicioufly taken a part of its fpecific charaGter ; 
the leaves of this, however, though always prefent, are fometimes fo clofely preffed to the radii, as not to be 
immediately vifible; the {tyles too, in general, are bent or bowed back to a greater degree than in the infefta. 
This plant is very common in the neighbourhood of London, in the fituations Ray defcribes, flowering in 
july. Though the z7/2//a may fometimes prove a troublefome weed, this, from its place of growth, is in no 
degree fuch. | 
Scopo.i obferves, that as the feed is not flat, nor has a margin, it cannot be confidered as a Tordylium s 
he remarks alfo, that he has feen the cultivated plant with an involucrum of one leaf, and without any ; as this 
is quite contrary to our experience, we fufpect he was deceived by the leaves of the involucrum being preffed 
clofe to the radii, which, as we have before obferved, very often happens.
