three Species of Trifolium. 219 
He fays of this Trefoil of his, that it is by far larger than the next 
preceding, viz. the a/pefre; that it has alfo thicker ftems; that its 
leaves are firiata, dorfo magis eminente et elato, laxa quadam veluti vagina 
caulem ampleétentia, duplo longiora et per oras denticulata; and, laftly, 
that the fpike is odlongior and major. All this, and efpecially what 
he fays of vaginz and foliola, does by no means agree with Trifol. 
medium. He mentions, indeed, at the fame time, that the ftalks 
are nodofi, or have genicula, and that the calyx is hairy; but by the 
firft I do not believe he underftands any flexure but the joints 
(nodi), which in the Trifol. rubens are larger than in any other, 
owing apparently to the very large, and as it were inflated, vaginæ 
of the ftipula. And as to the latter obfervation, the calyx of the 
Trifol. rubens is indeed always naked ; but fo is, for the moft part 
alfo, that of the medium. Still both of them have hairs on the teeth 
of the calyx; but the rubens has thofe hairs both longer and in 
greater abundance ; which, being divaricated, almoft cover the 
calyx, fo that at firft fight it appears to be all over hairy. Clufius 
therefore may. be excufed for thus defcribing it. 
This author immediately after fubjoins his Trifolit majoris iii al- 
tera Jpecies, of which he only obferyes, that. magnitudine vel foli- 
orum et florum forma aut colore, nibil aut quam minimum differt. Folia 
tamen anguftiora illorum longitudinem aliquantum excedere videntur, et florum 
Spica longior effe. This being by common confent Trifol. rubens a, the 
next preceding can be no other than the variety 8. For it is not 
probable that Clufius, who for his time was very accurate, fhould 
have found fo great a likenefs between two plants fo different as 
Trifol. rubens and medium are. Befides, as he has four-{pecies of his 
Trifol. majus, which he compares together, faying that, as to their 
external appearance, they are all fimilar; the chain will be unin- 
terrupted, if they are fuppofed to be Trifolium montanum, or perhaps 
IS ; : pannonicum,
