 Br. Fl. p. 218. E. B. t. 539. 



By roadsides, in waste places and cultivated ground, amongst corn, and on 

 chalky or gravelly banks and pastures, but rather uncommon in this island. Fl. 

 July — October. If. 



E. Med.— Fields near St. Lawrence, G. S.Gibson, Esq., in Phytol. for Nov. 1843. 



fV. Med. — About the ascent of the hill leading up to Hanipstead farm, in some 

 plenty. By the roadside between Idlecombe and Roughbnrough farms, fur nearly 

 100 yards. In a chalky hollow in a field behind, and nearly between Plash and 

 Buccombe, many very large plants. 



Achenium pale, short and truncate at the summit, -deeply furrowed and angu- 

 lar. Pappus a single row of very short unequally broad and jaLC;;ed scales. 



Completely naturalized in the noithern part of the United Slates and in 

 Canada. I remarked it aliundantly near Montreal and Quebec, as also in New 

 England, particularly at Boston. 



*** " Receptacle scaly. Pappus feathery." — Bab. Man. 



XXIX. Hypoch^eis, Linn. Cat's-ear. 



" Achenes striated, often beaked. Pappus feathery. Receptacle 

 chaffy. Involucre oblong, imbricated." — Br. Fl. 



1. H. radicata, L. Long-rooted Cat's-ear. " Stem branched 

 leafless glabrous, peduncles with small scales, involucres shorter 

 than the florets, leaves runcinate obtuse scabrous." — Br. Fl. p. 

 303. E. B. t. 831. 



fi. Leaves glabrous and shining, somewhat fleshy. 



In meadows, pastures and waste places, on banks and along hedges, &c. ; very 

 common; a troublesome weed on lawns and grass-plats, i^/. June — October. 2f. 



;6. Common on the banks of debris in Sandown bay, between that village and 

 Shanklin. 



Involucre sometimes quite smooth, but most frequently hispid with erect whitish 

 hairs or bristles. Acheuia forming globose heads, which are scarcely larger than 

 in H. glabra, exactly similar to those of that species in form, size, colour and 

 sculpture, but all stipitate, on usually rather long stalks. Pappus dirty white, in 

 several rows, smooth, or very slightly scabrous towards the top only. Puleoe and 

 receptacle as in H. glabra. 



From Hypocharis radicata both Thrincia hirta and Apargia hispida may be at 

 once known by the simple flower-stalks of the two latter, not branched as in Hy- 

 pocharis, and which are destitute of scales ; by the absence of paleee or chaff on 

 the receptacle ; and by having a sessile pappus, not stipitate or elevated on a 

 slender stalk, as is the case with our present plant. The glabrous, deeply lobed 

 and often pinnatifid leaves will enable the young botanist to distinguish Apargia 

 autumnalis from the present plant, to which it bears a slrong resemblance in its 

 branched flower-stalks, scaly, like the latter, beneath the glabrous involucre, but 

 upon close examination will be found to differ materially in the absence of paleae 

 to the receptacle, and in the sessile pappus. The presence of the little conical 

 tuft of cotton within the fistulose stem, near the receptacle, in Apargia autumnalis, 

 is perhaps the most decisive character. 



2. H. glabra, L. Smooth Cat's-ear. Nearly glabrous, invo- 

 lucre oblong regularly imbricated equalling the florets, achenes of 

 the central florets beaked, stem branched somewhat leafy, radical 

 leaves dentate -sinuate. Br. Fl. p. 203. E. B. viii. t. 575. Fl.
