EXPLANATION OF PLATE VIL 



Fig. 1. Pmvs pinea. Stone-pine. The fir tribe. (Family Con^/era;.) A native of 

 ihe soir.h of Europe. The head low and branching. Leaves of a sea-green colour, 

 acicular, forming an egret upon the summits of the branches. Strobilums large, ovate, 

 thick; served up in desserts in Italy and France. This tree, according to Loudon, 

 fonns a distinguished ornament of the villas of Rome and Florence. 



Fig. 2. Aeies picea. Fir-tree. {Coni/ercB.) Trunk rectilinear, vertical. Branches 

 forming a pyramid; sub-verticillate, very open. Boughs pendent. Leaves small, 

 linear, acute. Strobilums cylindrical, pendent. A tree common to mountainous re- 

 gions in the north of Europe, and in the United Slates. 



Fig. 3. Cycas circinalis.* A small difficious tree of Lidia, resembling the palms 

 in its aspect. Stipe vertical, cylindrio. Leaves pinnate; leafets lanceolate-linear. 

 Petioles spinose. Spines leafy. Staminate flowers in a catkin. JPistillate flowers in 

 spikes. A fertile plant showing the fructification at a. The pith of this plant affords 

 an article called Sago, superior to that brought from the West Indies under that name. 

 This was placed by Linneeus in the family of the Palms, and afterward classed among 

 Ferns. According to Mirbel's drawing and description, the first arrangement was 

 most natural. 



Fig. 4. Feitillaeia imperialis. Crown-imperial. {LiliacecB.) Bulbous plant, 

 two or three feet in height ; a native of Persia. Leaves radical, elongated, ensiform. 

 Scape naked, vertical. Flowers large, terminal, peduncled, umbelled, pendent. Pe- 

 rianth six-sepalled, campanulate. Bracts numerous, elongated, leafy, erect, crowning. 



Fig. 5. Lycopodium ce?-?!tm7?i.t Stem erect, branching. Leaves scattered, seta- 

 ceous, inflated. Spikes small, ovate, drooping. Cryptogamous. 



Fig. 6. Digitalis purpurea.t Fox-glove. {Scrophularice.) Biennial, native of 

 mountainous and sandy regions of Europe. Stem generally simple, leafy below. 

 Leaves alternate, oval-lanceolate ; the radical leaves larger. Flowers in a spike, uni- 

 lateral, peduncled, pendent. Corolla tubular, campanulate. 



Fig. 7. Nabcissus poeti(ms.% {Narcissi or AmaryUidecB.) Bulbous plant, ten or 

 twelve inches in height. Native in the meadows of Italy and the south of France. 

 Leaves radical, erect, riband-like. Scape naked, uni-flowered. Flower drooping, 

 spathaceous. 



Fig. 8. LvcopODiuM alopecuroides. Native of South America. Branches fall and 

 take root at their extremities. Leaves linear, subulate. 



Fig. 9. DoDEcATHEON meadia. (PrimulacecB.) Herbaceous plant, eight inches 

 high ; originally a native of Virginia. Leaves radical, spreading, oblong. Scape 

 naked, erect. Flowers pedicelled, umbelled, pendent. Corolla five-parted, the divi- 

 sions reflexed. 



* This plant is the principal genus of an order not recognised by Jussieu, the Cycadese. first proposed by 

 Ventenat and established by M. Richard. In the cylindrical stem and pinnate leaves, this order resembles 

 the Palms ; in many other characteristics, particularly in the organization of the fruit, it approximates to the 

 Coniferse ; in the mode of developing leaves, it bears a relation to the Ferns. 



t This genus belongs to the natural order Lycopodiacese, being, according to Lindley, "intermediate be- 

 tween Ferns and Coniferaj on the one hand, and Ferns and Mosses on the other ; related to the first of those 

 tribes in the want of stamens and pistils ; to the second, in the aspect of the stems of some of the larger 

 kinds ; and to the last, in their whole appearance." M. Brogniart supposes that in the primitive ages of ttia 

 world, these plants attained a gigantic size, equal to tlie largest forest trees of the present day ; this opinion 

 arises from discoveries made in coal mines, where, along with Ferns, are found what appears like re- 

 mains of species of this tribe. At present their habit resembles that of the Mosses ; they are usually low, 

 prostrate plants. 



: Lindley says, Digitalis forms a connecting Unk betvv'een Scrophularise and Solanes in its relation to 

 Vcrbascum, both genera having alternate leaves. 



§ This order is allied to AsphodeleEe and LiliaceiE, in the appearance of various organs, but distinguished 

 from them by its inferior germ. The corona or nectariferous cup of the Narcissus is considered by Lindley, 

 to be nothing more than an organ formed of an extra number of stamens, developed in a petaloid state. 

 The same author remarks, that " there is in this whole order a strong tendency to form another sot of sta- 

 miniferous organs between the perianth, and those stamens that actually develop."
