Orizaba, Mexico ; F. Miiller, 302, in Herb. Mart. Nearest to 

 7*. adenophijJla, 8t. Hil., but a smaller, slenderer plant with much 

 smaller flowers and narrower leaves, and not nearly so glandular. 

 The head of flowers is remarkabl}^ compact and globular.

 numerosi, ramosi vel subsimplices, circa f pedales, angulosi, sub- 

 glabri. Folia fere omnia 4-5 verticillata, f poll, longa, glanduloso- 

 punctata ; infcriora obovata, aj)iculata ; superiora lanceolata vel 

 linearia, acuta. Fiacemi capitati, compacti, subglobosi, circa 

 5-6-lin. longi ; bracteae lineares vel subulatae, pedicellos aequantes, 

 usque ad anthesim persisteutes. Flores 2 lin. longi, pedicellati ; 

 pedicelli graciles, glabri, flores subsequantes. Sepala exteriora 

 ovata, superius xmullo majus ; alse membranacefe, obovatae, 

 corollam includentes. Carina pulchre cristata ; cristtB laciniae 

 numerosse, lineares. Ovarium obcordatum ; stylus curvatus, 

 medius incrassatus ; stigma pai)illosum. Capsula ovalis. Semina

Paraguay. Villa Eica, sur les coUines incultes ; Bal., 2192. 

 Eeadily distinguished from its congeners by its nearty spherical 

 racemes, long- stalked flowers, long persistent bracts, and glandular 

 leaves; perhaps nearest to F. ndenophy I (a, but the racemes are of 

 quite a different shape, and the flowers have much larger stalks. 



23. P. LEUCANTHA, uob. H. sp. Eadix crassa, descendens. Caules 

 valde numerosi, tenues, graciles, 3-5 poll, longi, glabri, angulati 



^ vel etiam subalati. Folia conferta, lineari-lanceolata, acuminata. 

 4-5 lin. longa, glanduloso-punctata, plc.-umque 4-5 verticillata. 

 Eacemi breves, conici, densiilori, \-^ poll, longi ; bracteae subulatfe, 

 flores subaiquantcs, subpersistentes, alabastra excedentes. Flores 

 parvi, 1-lin. longi, subsessiles, albi. Sepala exteriora ovalia, 

 superius paullo majus ; ahe ovales, corallam includentes. Carina 

 pulchre cristata. Ovarium parvum. Capsula alis persistentibus 

 multo brevior. Semina nigra, sericeo-hirsuta ; arillodium baud 

 galeatum, appendices duas gerens, tenues, semini subjequilongas. 



Paraguay ; Cerro-Perron ; Bal., 2190. Well-marked by its 

 crowded whorls of narrow, acuminate, glandular leaves, and short, 

 conical, somewhat comose racemes of small white flowers.
