has seven published names. The fourth and last in the se< 

 is the macroccphalitm group, recognized by usually having some 

 of its leaves with more than three leaflets, these varying in num- 

 ber from three to nine. In this group there arc nine published 

 names. This makes a total of forty-one names that must be 

 considered as .'pecies or placed in m r.< r.\ my. A number of dis- 

 crepancies that have been handed down in botanical literature 

 should also he corrected. 



It has been our aim in these studies to consider that there 

 are no new species of clovers, and to find a place for all speci- 

 mens sul mitted to us among those already described. In a re- 

 cent collection of Trifolium, however, sent t ) us by Mr. Win. C. 

 CiiMck, of Union, Union count} - , Oregon, a low plant labeled T. 

 A'i//o/i, but very different from that species in all respects, came 

 to our notice. Its habit and floral structure readily placed it in 

 the latifolhini group, of which there are seven members, as fol- 

 lows: T. Aitonii Rydb., 7". Covillci House, T. Haydeni Porter, 

 T. latifolium (Hook.) Greene, T. orbiculatum Kennedy and Mc- 

 Dermott, T. oreganum Howell, and T. sJiastensc House. We 

 have given each of these careful and prolonged study, and have 

 had access to type or type number material of all except T. Co- 

 villei. The excellent description of the last named, however, 

 in the Botanical Gazette 41: 1906, precludes any possibility of 

 its being that species, particularlv if the illustrations of the vex- 

 illi of the two are compared. The calyx of 7\ Covillei'xs men- 

 tioned in the original description as "'sparingly hairy above," 

 but the accompanving figure shows it as glabrous. 



We desire therefore to propose Mr. CusickAs plant as a new 

 species of Trifolium with the following description and accom- 

 panying plate showing its structural characters. 



Trifolium iimltipeditiiculatiim n. sp. 



A low, somewhat hairy plant with running rootstocks an and 

 occasional long tap root, numerous peduncles and short, thickly 

 matted stems. The flowers are a rich purple, becoming larger, 

 brownish, and reflexed at maturity. 



Plant about 1 dm. high, perennial, not iuvolucrate: stems 

 verv short and matted: stipules clustered at the base of tbe stems,
