452 Mr. Babington on several new or imperfectly understood 



prominent hairs, so as to appear when closed like a little bur ; each sepal 

 ovate-lanceolate, blunt, with a diaphanous margin ; petals and stamens 

 rising from a fleshy disk, the former resembling the filaments of the an- 

 thers, but alternate with them, and, as it appears to me, in an exterior 

 whorl ; stipules large, acute, membranous, ciliated. 

 On gravelly ground, near Colney Hatch, Barnet. Hudson, 71..} July, August. 



Mr. E. Forster suspects that this plant is only annual. Messrs. Milne and 

 Gordon in their Indigenous Botany, i. 455, say, " We found it in a field at 

 Finchley and at Colney Hatch near Barnet, where Hudson observed it." It 

 has not, I believe, been found since the publication of that work in 1793.

Whole plant of a pale yellowish green ; stems thickly covered with very minute 

 curved hairs, pointing downwards ; Jlowers much smaller than in H. hir- 

 suta, and more numerous in each of the clusters, which are set so closely 

 on the lateral branches as to present the appearance of a long leafy spike ; 

 calyx glabrous ; sepals oblong-ovate, rather acute ; corolla and stamens as 

 in the last ; stigmas small ; stipules lanceolate, acute, membranous, slightly 

 ciliated. 



The description given under H. glabra in Dr. Hooker's Brit. Fl. belongs to 

 H. ciliata, as does the Cornish locality. In Sir J. E. Smith's herbarium three 

 specimens are preserved on one paper as H. glabra -, No. 1 . " Herb. D. Rose," 

 which is correct ; No. 2. from Cornwall, and No. 3. from Halle, both of which 

 belong to my H. ciliata, described below. Gaudin, Fl. Helv. ii. 243. describes 

 the clusters as opposite to the leaves, but I suspect that he has taken the 

 lateral branches mentioned above for single clusters, in which case they would 

 appear to be opposite.
