less triangular inform. Anthodes smaller and fewer. Phyllaries 
paler, narrower, and more acute; the outer ones rather longer in 
proportion, and somewhat recurved. 
This is not II. dentieulatum of Smith's Herbarium, nor of 
11 English Botany ; " both the specimen and the figure belon"- to 
IE. strictum. It can scarcely be that of Griesbach, as (judging from 
the plate in Reichenbach's " Icones Florae Germ, et Hclv. " Vol. 
XIX, Tab. MDXIII. Pig. 2) that has the lower leaves gradually 
narrowed, and not distinctly petiolate ; and is certainly distinct, if 
Eeich. I.e. Tab. MDXLV. can be referred to H. dentieulatum, Griesb. 
The only wild specimen I have seen which could be referred to 
IT. Borreri is one in Smith's Herbarium from Switzerland, named 
II. 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. II. C. Watson received the livin"* 
plant from Mr. Borrer, who got it from Mr. E. Forster'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- 
tieulatum, 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 sec 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 Porster. 
Sub-Order IV.— AMBROSIACiE.* 
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 appearance of 
a nut. Corolla tubular in the male flowers, generally absent in the 
female. Anthers not united into a ring. 
Small-toothed Hawkweed. 
GENUS XLII.—X A N T H I U M. Tournef. 
Anthodes monoecious, homogamous. Male anthodes many- 
flowered ; pcricline sub - globose, of free phyllaries in a single 
series ; clinanth with palea) ; florets with the corolla clavate, 
1 This appears to be properly a group of the sub-order Corynibiferse ; 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.
