T T"?^^^' Robinson. I saw the type of this genus at Berkeley in 

 June, before the genus was published. To aU ppearances it was the same 

 as my number 23419, got at Acaponeta Nayarit in 1927, a cursory 

 examination. But on studying it microscopicaHy I find my material is 

 Eupatonum monanthum with the characteristic pappus of that genus, and 

 the long and club-shaped stigmas, tl is rather curious that two genera 

 should be so much afike and growing so near to each other. They remind
