GREENMAN. — NEW ANGIOSPERMS FROM MEXICO. 75 



at first glandular pubescent : capsule oblong, triangular, 5 to 8 mm. long, 

 hispklulous : seeds small, round, about 1 mm. in diameter ; surface 

 slightly honeycombed. — Mexico. State of Oaxaca : in dry thin soil, 

 Cuesta de San Juau del Estado, altitude 1850 m., 20 August, 1894, C. G. 

 Pringle, no. 4831 (hb. Gr.), distributed as '■' Sisyrinchium Hartwegii, 

 Baker form"; Valley of Etla, altitude IGGO m., 2 July, 1895, L. C. 

 Smith, no. 556 (lib. Gr.). Federal District: lava fields near Tlalpam, 

 altitude 2250 m., 16 August, 1902, C. G. Pringh, no. 8G5G (hb. Gr.). 

 The species here described is distinguished from Sisyrinchium Hart- 

 wegii, Benth., which is apparently the same as S. tenuifolium, Humb. & 

 Bonpl., by the less branched and less flexuous scapes, the short-pedun- 

 culate spathes, and finally by the hirsutish character of the upper part 

 of the scape and inflorescence. 



Sisyrinchium Palmeri. Roots tuberous, fascicled, 2 to 3 cm. long, 

 5 to 7 mm. thick in the dried state : leaves linear-attenuate, 0.5 to 2.b 

 dm. long, somewhat sheath-like below and more or less purplish just 

 above the base, smooth and glabrous : scape 1.2 to 2 dm. high, flattened, 

 usually narrowly winged, branched above, bearing 2 to 4 pedunculate 

 inflorescences : peduncles 1,5 to 4 cm. in length, mostly exceeding the 

 nodal bract: spathes of two slightly unequal bracts, 1.5 to 2 cm. long, 

 3-7 -flowered : pedicels 2.5 cm. or less in length: perianth yellow, 1.5 

 to 2 cm. in diameter : ovary glabrous : capsule oblong, G mm. long, 

 4 mm. thick, rather sharply 3-angled, smooth and glabrous : seeds about 

 1 mm. long and broad. — Mexico. State' of Jalisco : Rio Blanco, 

 June, 1886, Dr. Edward Palmer, no. 18 (hb. Gr.) ; gravelly plains 

 near Guadalajara, 15 July, 1902, C. G. Pringle, no. 8644 (hb. Gr.). 



SiSYRixCHiUM QUADRANorLATUM, Klatt, Linntea, xxxii. 284. Speci- 

 mens secured by Mr. C. G. Pringle on Mt. Orizaba, Mexico, at an ele- 

 vation of 4000 m., 1901, no. 8566 (hb. Gr.), accord well with the original 

 characterization of the above species, which was based upon plants 

 collected by Liebmann on Mt. Orizaba in 1841. It may be said, how- 

 ever, that the color of the perianth in Mr. Pringle's specimens is dis- 

 tinctly blue, not yellow as was stated by Klatt to be the color of the 

 flowers in the Liebmann plant. There is in the Gray Herbarium a 

 specimen from the Liebmann collection, which was obtained on Mt. 

 Orizaba at an elevation of 3000 m., and the label accompanying this 

 plant bears the name " Sisyrinchium scabrum, Schlecht., var. exaltatum." 

 Although this specimen was determined by Klatt, it does not seem to 

 have been cited byhim in Liunaea xxxii. under the name which it bears. 

 It seems altogether probable that the Liebmann plant in the Gray
