less triangular in form. Anthodes smaller and fewer. Phyllaries 

 paler, narrower, and more acute ; the outer ones rather longer in 

 proportion, and somewliat recurved. 



Tliis is not H. denticulatum of Smith's Herbarium, nor of 

 " English Botany ; " both the specimen and the figure belong to 

 H. strictum. It can scarcely be that of Griesbach, as (judging from 

 the plate in Reichenbach's " Icones Elorse Germ, et Helv. " Vol. 

 XIX. Tab. MDXIII. Fig. 2) that has the lower leaves gradually 

 narrowed, and not distinctly petiolate ; and is certainly distinct, if 

 llcich. I.e. Tab. MDXLV. can be referred to H. denticulatum, Gr/esi. 



The only wild specimen I have seen which could be referred to 

 n. Borreri is one in Smith's Herbarium from Switzerland, named 

 H. cydonifolium ; but it is not the plant so named by Villars, because 

 it is not glandular-hairy all over. 



The history of H. Borreri is by no means satisfactory in proving 

 that it has occurred in Britain. Mr. H. C. Watson received the living 

 plant from Mr. Borrer, who got it from Mr. E. Eorster's garden, 

 with the information that he had it from Dickson, who found it in 

 Harehead Wood. Smith mentions this station under his H. den- 

 ticulatum, but there are no specimens of it in his Herbarium. It 

 is greatly to be wished that some botanist would explore Hare- 

 head Wood, to see if this plant really exists there, as it is quite 

 possible that the plant found by Dickson may not have been the 

 same as that received by Mr. Borrer from Eorster. 



Sub-Oeder IV.— AMBROSIAC^.* 



Anthodes monoecious ; the male consisting of numerous florets 

 surrounded by distinct or united phyllaries ; the female of one or 

 two florets included in an involucre, with the phyllaries united 

 and hardening over the fruit, so as to give it the aj)pearance of 

 a nut. Corolla tubular in the male flowers, generally absent in the 

 female. Anthers not united into a ring. 



Small-toothed Haiokweed. 



GENUS XLII.—X A N T H I U M. Tournef. 



Anthodes monoecious, homogamous. Male anthodes many- 

 flowered ; pericline sub - globose, of free phyllaries in a single 

 series ; clinanth with paleas ; florets with the corolla clavate. 



* This appears to be properly a group of the sub-order Corymbiferae ; but, as all 

 the connecting links are wanting in the British Flora, it is here removed from the 

 place which it ought to occupy in a general Flora.
