160 PROCEEDINGS OF THE AMERICAN ACADEMY 



Iris Missouriensis, Nutt. At Lerios, in the high mountains east 

 of Saltillo (1302). 



Iris Florentina, Linn. In the same region (2009). Unlike 

 any native North American species, and probably cultivated. 



TiGRiDiA VanHouttei, Roezl. At Guanajuato (Duges). Known 

 as " Jahuiqiie " ; bulbs eatable, with the taste of chestnuts. The 

 same as 79 and G28 Ghiesbreght. 



Nemastylis tenuis, Benth. & Hook. (C/iIamydosfylis tenuis. 

 Baker.) At Guajuco, Nuevo Leon (2008). Flowers indigo-blue. 



Nemastylis multiflora, Benth. & Hook. [Chlamijclostijlis mul- 

 tijloriis, Baker.) At Morales, San Luis Potosi (538 Schaifner) ; 

 Parry & Palmer, without number. This is probably Baker's species 

 in part. The flowers are larger than described by him, the perianth 

 being 12 to 14 lines long, and the column of filaments nearly half an 

 inch long. The capsules are oblong, 8 lines long ; seeds obliquely 

 oblong-ovate, finely tuberculate ; connective as broad as the anther- 

 cells. 



Neaiastylis nana. Bulb small, with dark brown coats : leaves 

 very narrow, 3 to 6 inches long : scape an inch or two long, bearing a 

 single elongated leaf" and one or two peduncles; spathes 9 lines long, 

 the outer valve shorter and acuminate, the inner acute and closely 

 convolute, 1-flowered; pedicel included: perianth greenish white, the 

 nearly equal segments 4 to 7 lines long: staniineal tube a line long, 

 the anthers with very narrow connective, 3 lines long : styles half as 

 long, very slender, ascending: capsule oblong-ovate, 3 lines long. — 

 In the Escabrillos Mountains, San Luis Potosi (539 SchafFuer) ; 887 

 Parry & Palmer. 



SiSYRiNcmuM TENUiFOLTUM, Humb. & Bonpl. At Lerios, Coahuila 

 (1301), and near Morales, San Luis Potosi (528 Schaffner) ; 878 and 

 880 Parry & Palmer, and 523 and 2G64 Bourgeau. It is the same 

 also as 231 Hartweg, which is probably the type of S. Ilartwegi, 

 Baker, of which the name only appears to have been published, with- 

 out description or other means of identification. 



SiSYRiNCHiuM SCABRUM, Cham. &, Schlecht. At Lerios, Coahuila 

 (2007), near Morales (529 Schaffner), and at Guanajuato (Duges). 

 Differing little, except in its scabrous margins, from S. anceps, Cav., 

 which also occurs in Mexico (Gregg; 222 Hartweg; 879 and 879 J 

 Parry & Palmer). 



SiSYRiNCHiUM ScHAFFNERi. Root of slender fibres : scape simple, 

 1 to 4 inches high, equalling or exceeding the rather broad leaves (J 

 to over 1 line wide) ; margins distantly serrulate : spathe 2-6-flowered,
