Stem slightly zigzag, smooth, with a few raised lines, leafy 
to the base. Stipules with “reflexed”’ auricles. Branches of the 
petioles spreading. Panicle lax, irregularly pyramidal, with 
ascending branches. Flowers “erect”? Primary bracts resem- 
bling the leaves, but very small; secondary ones entire. Achenes 
regularly oval-ovoid, very pale olive. Anthers apiculate. Leaves 
bi- or tri-pinnate. Leaflets 3- to 7-lobed. 
Rare on chalky hedge-banks and in stony places. ‘“ Allington 
Hill, Little Trees Hill, Gogmagogs, Fullbourne, and roadside be- 
tween Newmarket and Snailwell, Cambridgeshire; also Cheddar 
Cliffs, Somerset.” —(Bad.) 
England. Perennial. Summer. 
Smaller and less branched than T. Kochii, which it resembles in 
the form of the fruit, and of which it may be only a sub-species. 
Stem 13 to 3 feet high, not closely striate, as in T. minus, but with 
distant raised lines, so that it may be termed angular. Of this 
plant I possess no specimen, but, through the kindness of Professor 
Babington, I have had the opportunity of examining those in his 
herbarium; and I have also seen specimens in the British Museum, 
collected by the Rev. W. W. Newbould at Fullbourne, which cer- 
tainly belong to this species. A plant from Disseth, Flintshire, not 
in fruit, may also belong to it. These agree well with Reichen- 
bach’s figure quoted above, provided that the flowers be erect, as 
Professor Babington believes ; but this is a point almost impossible 
to determine from dried specimens. I feel considerable doubt 
whether any of this group, of which T. minus is the type, have the 
flowers erect when fully expanded, and before the fruit has begun 
to set. Ifthe flowers be drooping in the present species, there can 
be no doubt it is T. collinum of Wallroth, with which it agrees in 
all other characters. I hope, however, next year to examine the 
plant when growing, and clear up this point.
