In LINNiEAN ARRANGEMENT 



Order III.— POLYGNIAc-Many Pistils. 



Magnolia. Sepals 3, deciduous. Petals 6 — 12, in concentric series. 

 Carpels 1 — 2-seeded, persistent, forming a strobile-like fruit. Seeds coated 

 with a fleshy aril. Magnollacccs, p. 14. 



LiRiODENDRON. Sepals 3, deciduous. Petals 6. Carpels (samarse) im- 

 bricated in a cone, 1 — ^2-seeded, not opening, attenuated. Magnoliacea, 

 p. 15. 



AsiMiNA. Calyx deeply 3-parted. Petals 6, spreading, ovate-oblong; 

 inner smallest. Anthers many, subsessile. Carpels usually 3, ovoid or 

 oblong-sessile, pulpy within. Seeds many. Anonaccce, p. 15. 



Hydropeltis. Calyx of 3—4 sepals. Petals 3 — 4. Ovaries G — 18. 

 Carpels oblong, acuminate, 1 — 2-seeded. Cabombacea, p. 18. 



Nelumbium. Calyx petaloid, of 4—6 sepals. Petals numerous. Car- 

 pels numerous, deeply immersed in the upper surface of a turbinate recepta- 

 cle or torus, 1-seeded. * NelumbiacecB, p. 18. 



Obs. The remaining genera belong to the Order RanunculacecB, p. 3. 



CLASS XIII.— DIDYNAMIA.— 4 Stamens; 2 longer than the other 2. 



2 Orders.— 1. GYMNOSPERMIA.— See& apparently naked. 

 2. ANGIOSPERMIA.— Seeis in a distinct capsule. 



Obs. The genera of this class form a very natural group, having irreg- 

 ular or bilabiate flowers, with mostly 4 stamens ^2 longer) ; but sonlfetimes 

 2 are abortive, and hence such are arranged artificially in the class Diandria. 

 The whole will be more easily, as well as correctly, studied, by the Natural 

 Orders. The genera belonging to the order Gt/vinospermia will be found in 

 the Natural Order Labiates, p. 270 ; those belonging to Angiospermia, in 

 the Natural Orders BignoniacecB, p. 241 ; Pedaliacece, p. 242; Orohan- 

 chacea,, p. 257; Scrophulariacece, p. 258; VerbenacccB, p. 283, Sindi Acantha- 

 cea, p. 286. 



CLASS XIV.— TETRADYNAMIA.— 6 Stamens ; 4 long and 2 short. 



Obs. This class is entirely natural ; and it is therefore altogether unne- 

 cessary to repeat the generic descriptions. It is identical with the Natural 

 Order Crucifercc, p. 23. I have, chiefly for the sake of convenience, pre- 

 served the Linnaean division into Slliculosce and SUiquosa. Gynandropsis 

 and Polanisia (^Cleome Linn.) usually arranged under this class, form the 

 order CapparidO^, p. 33. 



CLASS XV.— MONABELPHI A.— Filaments.combined in one set. 



Order I.— PENTANDRIA.— 5 perfect Stameiis. 



Passiflora, Calyx 5-parted, colored. Petals 5 or none, inserted into 

 the calyx. Crown of many filiform rays. Berry often pulpy, rarely sub- 

 membranaceous, pedicelled. Fassijloracecc, p. 119. 



{Geraniuvi in Order DECANDRIA.) 



Order II.— DECANDRIA.— 10 Stamens. 



Geranium. Sepals 5, equal. Petals 5, equal. Stamens 10, all fertile ; 

 5 alternate ones longer, and with nectariferous scales at the base. Carpels
