EXPLANATION OF PLATE VIL 



Fi.2 . PiNUs pinca. Stone-pine. The fir tribe. (Family Coni/ercc.) A native (iJ 

 the south 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, ovatft 

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

 forms a distinguished ornament of the villas of Rome and Florenie. 



Fig. 2. Abies picea. Fir-tree. {Conifcrcc.) Trunk rectilinear, vertical. Branches 

 forming a pyramid; sub-verlicillate, 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 States. 



Fig. 3. Cycas circuialis.* A small dioecious tree of India, resembling the palms 

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

 Petioles spinose. Spines leafy. Siaminate flowers in a catkin. Pistillate flowers in 

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

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

 This was placed by Linnaeus 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. Fritillaria 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 cernuum.i Stem erect, branching. Leaves scattered, seta- 

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



Fig. 6. Digitalis purpxirca.X Fox-glove. {Scrophularicc.) Biennial, native o( 

 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. Narcissus poeticus.% {Narcissi or Amaryllidecc.) 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, 

 Bpathaceous. 



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

 take root at their extremities. Leaves linear, subulate. 



Fig. 9. DoDScATHEON TTieadia. (PrimulacecB.) Herbaceous plant, eight inches 

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

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

 sions reflexed. 



* This plant is the principal genus of an order not recojjnised by Jussieu, the Cycadeae, first proposal by 

 t^entenat and established by M. Richard. In the cylindrical stem and pinnate leaves, this order resemble? 

 the Palms ; in many other characteristics, particularly in the oreanization of the fruit, it appro.vimates to iht 

 Coniferaj ; in the mode of developing leaves, it hears a relation to the Ferns. 



t This genus belones to the natural order Lycopodiacea;, being, according to Lindley, " intermediate be- 

 tween Ferns and Conifera; on the one hand, and Ferns and Mosses on the oilier; 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. Broijniart supposes that in the primitive ages of tlie 

 wprld, these plants attained a gigantic size, equal to the largest forest trees of the present day ; thls.opinion 

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

 maLns of species of this tribe. At present their habit resembles that of the Mosses ; they aio usually low 

 prf>strate idanLs. 



I Lindley says. Digitalis fjrms a connecting link between Scrophularia; and Solanoaj in iu relation Va 

 Vcrbascum, both genera having alternate leaves. 



^ § This order is allied to Asphodelete and Liiiaceae, in the appearance of various organs, but distinguished 

 Tom them by its inferior eerin. The corona or nectariferous cup of the Narcissus is con.?idered by Lindley, 

 to be nothing more than an organ formed of an extra (timber of stameni!, developed ii> a netaloid stati' 

 / •/ iume author remarks, that " there is in this whole order a strong tendency to fbrru anolJier set of sta 

 r> • <erou» organs between the perianth, and those stamens that actually devtdop."
