Hosackia Alamosana,' n. sp. Procumbent, rooting at the joints, glabrous or the 

 younger parts with appressed Imira: leaves 3 to 5-piunate; stipules 1 to 2 lines 

 long, foliaceous, ovate, acute; leaflets obovate, obtnse, 2 to 5 lines long: 

 peduncles slender, 2 to 4 inches long, 1 to 4-llowered, mostly 2 : bracts 1, seta- 

 ceous : flowers small 2 to 3 lines long : calyx tube less than a line long ; its lobes 

 almost as long and very narrow: corolla yellow : pods 10 to 15 lines long, terete, 

 erect, 12 to l,")-8eeded; seeds turgid, oblong, lucid. — Half way up the mountain 

 in a wet spot. Alamos. March 20 to April 8. No. 400. Dr. Palmer says : "The 

 plant roots at every joint and forms a thick sod." The plant is nearest If. august- 

 tijolia of Mexico, but differs from it especially in its procumbent habit; its fewer 

 an<l obtnse leaflets; smaller flowers and bracts. It is questionable, whether 

 Seemnnn's (No. 121 of IJotany Herald) broader leaved form from this same range 

 of mountains may not really be our plant. Mr. Hemsley (Biol. Ceut.-Amer. i. 

 234), who has probably seen Seemaiui's ))lant, however, kei)t it as a possible 

 variety of 77. atigusii/olia and refers to it Parry and Palmer's No. 140, which is a 

 very different plant from ours. 

 It diti'ers from 77. rtpens Don. (which species Mr. Hemsley has omitted in the IJiol. 



Cent.-Auier.) in its fewer leaflets (1 to 3 pairs), and these not mncronulato; licads 



fewer flowered (mostly 2, rarely 4) ; and glabrous calyx.
