Aqutlegia Skinneri, Hook. Identical with the plant figiu'ed in 

 Bot. Mag. (1842), t. 3919, which is said to have been raised from seeds 

 collected in Guatemala by G. U. Skinner. It would seem that the 

 plant itself has never before been collected, either in Guatemala or 

 elsewhere. As it has proved to be perfectly hardy in the gardens of 

 England, a tropical habitat is not probable, especially as the genus 

 otherwise is confined to temperate regions. — Cumbre (336). 



Delphinium leptophyllum, Hemsl. The claws of the lateral 

 petals, however, have an appendage at base, the absence of which is 

 made a characteristic difference between this species and D. ju'dati- 

 sectum, Hemsl. Possibly the two species are not distinct. — Noro- 

 gachi (424). 



Sisymbrium incisum, Engelm. — Norogachi (421). 



Cleome (Physostemon) melanosperma. Annual, slender, erect 

 and branching, two feet high, glabrous or very sliglitly puberuleut : 

 leaves trifoliate, the thin leaflets lanceolate to narrowly lanceolate, more 

 or less acuminate, mostly cuueate at base, the blade (1 or 2 inches long) 

 exceeding the petiole ; the uppermost floral leaves simple, linear- 

 lanceolate and sessile : pedicels slender, exceeding the bracts : sepals 

 distinct, linear ; petals " creamy white," 3 or 4 lines long : capsule 

 narrowly oblong (8 or 9 lines long), attenuate at each end, the stipe 

 about three lines long : seed dull black, irregularly undulate-reticulate. 

 — Hacienda San Miguel (94). 



lONiDiUM parietari^folium, DC. ? A slender erect branching 

 annual, the stem and branches somewhat villous, and with a line of 

 dense iDubescence: some of the lower leaves opposite, all lanceolate, 

 acute or acuminate, mostly narrowed to a slender base, bluntly 

 serrate, nearly glabrous, 1 to 2^ inclies long : pedicels 4 to 6 lines 

 long, or in the main axils an inch long : lower petal white or purplish, 

 four lines long, the upper tipped with dark purple. — Haciendas San 

 Miguel (93) and San Jose (25). Resembling 2G61 Bourgeau, 35 Bili- 

 mek, and 472 Botteri, all from Orizaba, as well as specimens collected 

 by Purdie and Holton in New Grenada, and by Fendler (2419) in 

 Venezuela, except that these are all not villous and have the leaves more 

 acutely serrate. IMr. Hemsley refers this species to /. riparium, II BK., 

 but Eichler identifies this last with /. oppositi folium, leaving De Can- 

 doUe's species distinct. 859 Wright, from Sonora (/. riparium, var., 

 Gray, PL Wright. 2. 10), in fruit, is not villous, and has the capsules 

 nearly sessile and sometimes subfascicled in the axils. 



Amoreuxia pal:matifida, DC. {A. Schiedeana, Planch.) — Ha- 

 cienda San Miguel (Q).
