forms it approaches very near to P. americana. It occurs in Tropical 

 Mexico, Honduras, and Guatemala, and doubtfully in Ecuador. 

 Wawr., 801; Hook., 1843: Seem., 761 (?). 



t4. P. Xutkana, DC, Prodr., i., 330. With this A. Gray has 

 identified, and no doubt correctly, P. cucullata, Benth., PI. Hartw., 

 299, from California, distinguished from all its allies, except the 

 following, by the cucullate carina. It is recorded from California, 

 Lobb, 277, and Sierra Nevada. P. cornuta, Kellogg in Proc. Calif. 

 Acad., i., 61 ; P. californica, Nutt. in Geol. Surv. Calif., 59. 



P. siibspinosa , S. Wats, in Amer. Nat., vii., 299. Perennis, 

 herbaceus, glaber vel plus minus pubescens. Caules 2-8 poll, alti, 

 superne ramosi, rami saepe spinosi. Folia sparsa, ^-1 poll, longa, 

 elliptica vel oblanceolata, acuta vel obtusa, ad basim attenuata. 

 Kacemi laxi, pauciflori ; bractese parvae, scariosae ; pedicelli demum 

 reflexi, floribus breviores. Sepala ciliata vel eciliata ; al® oblougae, 

 4-5 lin. longae, corollam aequantes. Carma cucullata, appendicem 

 latam saccatam gerens. Stylus linearis. Capsula orbicularis, 

 emarginata, breviter stipitata. Silver City, Nevada ; Kanab 

 Arizona ; Southern Utah, Parry, 32. Central Mexico, Pan*, et 

 •Palm. (1878), No. 42 (?). Obviously near P. Nutkana (P. cucullata, 

 Benth.), with which it agrees in the structure of the carina. It 

 is the only spiny Polygala of the Northern Continent ; but in some 

 of the localities the spines are only feebly or not at aU developed. 



5. P. huxifolia, H. B. K., v., 407 ; DC, Prodi-., i., 331. The 

 only specimen I have seen to which this name is attached, Graham, 

 134, from Mexico, doubtfully named by Mr. Bentham, in the Kew 

 herbarium, answers faMy well to Kunth's description. 



6. P. glandulosa, H. B. K., v., 404, t. 610; DC, Prodi*., i., 

 331 ; Nova Hispania, I have never seen. 



7. P. Parnji, A. W. Benn. in Hem. Diagn. PI. nov. Mex., ii. 

 Caulis basi perlignosus et ramosus ; rami tenues, pubescentes. 

 Folia lanceolata vel oblanceolata vel suborbicularia, apiculata, 

 infra in petiolum brevem attenuata, saepius pubescentia. Racemi 

 brevissimi, pauciflori ; bracteae ovatae, hirsutae, usque ad anthesim 

 persistentes. Sepala exteriora alas fere aequantia ; superius viride 

 et subbrevius ; duo inferiora subpetaloidea, hirsuta, ciliata ; alae 

 sepala exteriora vix excedentes, obovatoB, apiculatae. Carina 

 ecristata, ad apicem hirsuta ; petala lateralia fere usque ad basim 

 libera, carinam multo superantia. Ovarium subglobosum. Capsula 

 rotimda, vel latior quam longa, hirsuta. Semina (immatura) 

 hirsuta ; arillodio galeato. 



Central Mexico, Parr, et Palm. (1878), No. 40. The specimens 

 are imperfect, and have apparently been browzed down, but the 

 distinctly- stalked leaves (usually about 3 lin. long and 2 wide), 

 comparatively large external sepals, and apiculate wing-sepals, 

 clearly mark a distinct species. 

 To this section belong also — 



P. ovalifoUa, DC, Prodr., i., 331; Gray, PI. Lindh., 151 

 (= P. ovatifolia, Gray, PI. Wright., i., 39) ; very near to 

 P. americana. It occurs also in Mexico ; PaiT. ct Palm. 

 (1878), No. 43 ; et al.
