K. Odomtilt* has the leaves narrowed from the base, opposite, 

 linear-lanceolate, remotely serrate ; the floral leaves longer than the 

 Aowers; the corolla pubescent; the lobes of the lower lip oblong, 

 obtuse ; the anthers with two equal points, hairy. It is a native of 

 Europe, and is abundant in Great Britain in meadows, corn-fields, and 

 waste places. This plant is the Bartiia Odontita of Hudson, and 

 the Moxtitti rubra of Persooa. 



There are several other species of Euphratia. Although pretty 

 plants none of them will grow well in cultivation.

EU'PODA (from ti, and *w'i, jroSeis, a foot), Latreille's fifth 

 family of Tetnunerous Coleofttera. The great aiie of the posterior 

 thighs in many insect* of this family gives rise to the appellation. 

 The genus Sayru, many species of which, remarkable for brilliant 

 red, purple, and green colours, are brought from the East, and the 

 genus Crucerit, are types of sub-divisions of the family.

KT'RYALE (after on* of the Qorgons, in allusion to the threatening 

 armed appearance of the plant), a genus of Plants belonging to the 

 natural order A'ymphameta. It has' a calyx of 4 sepals inserted in the 

 torus, and adhering to it; 16-28 petals; numerous stamens; 16-20 

 carpels ; the fruit half-inferior, arising from the sepals ; petals and 

 stamens adhering half-way up. There is but one species of this genus, 

 . ferox, which is an elegant aquatic, covered all over with prickles, 

 with large peltate orbicular leaves, and bluish-purple or violet flowers, 

 about the size of those of the yellow water-lily. It is a native of the 

 East Indies in the lakes Gum toe and Oogra, also in the province of 

 Kianang in China. This plant presents a very singular appearance. 

 Its petioles and calyces are hispid with stiff priukles. The leaves are 

 about a foot in diameter. The root or rootstock contains starch, 

 which may be separated as food, or the root may be eaten, as is done 

 by the inhabitants of the districts where it grows. 



In cultivation, this phut must be kept in water in a hotbed or 

 stove. It will produce seeds if the pollen of the anthers, when it is 

 in full bloom, DO shaken on the stigmas. It can only be propagated 

 by means of ita seeds.

 Dr. Leach, and forming the second genus of the Parthenopiaus of 

 M. Milne- Ed wards, who remarks that it establishes the passage 

 between Parlkauupe or lambrut and the other OryrAyncAt. The 

 general form of the body and aspect approximates these crustaceans 

 to Parlkenope, whilst the disposition of their external auteuuic ia 

 similar to the conformation in Main. The carapace is nearly in the 

 form of a triangle with a rounded base, and is strongly tuberculated

and covered with asperities. The rostrum Is horizontal, and divided 

 nto two triangular horns. The eyes are small ; the orbiU deep, their 

 upper border very much projecting, and separated from the external 



angle by a slit The internal antenna are bent back longitudinally, 

 and the first joint of the external antenmo terminates at the internal 

 angle of the orbit The epistome is nearly square 1, and the third 

 joint of the external jaw-feet strongly dilated externally. The sternal 

 plastron ia nearly oval, and iU median suture occupies the two last 

 thoracic rings. The feet of the first pair are scarcely longer than the 

 succeeding one?; in the male they are rather long, whilst in the 

 female they are very short, hut leas than those of the second pair ; 

 the succeeding feet diminish progressively in length. Abdomen 

 consisting of seven articulations in both sexes.

EVERGREENS are plants which shed their old leaves in the spring 

 or summer after the new foliage has been formed, and which 

 quently are verdant through all the winter season ; of this nature arc 

 the Holly, the Laurel, the Ilex, and many others. They form a 

 considerable part of the shrubs commonly cultivated in gardens, and 

 are beautiful at all seasons of the yen-. 



The principal circumstance* in which Evergreens physiologically 

 differ from other plants are the hardness of their cuticle, the thickness 

 of the parenchyma of their leaves, and the small number of breathing 

 pores, or stomatas, formed on the surface of those organs. These 

 peculiarities, taken together, enable them to withstand heat and 

 drought with more success than other plants, but are often not 

 sufficient to protect them against Mich influences in excess, Hence 

 we find them comparatively uncommon in those parts of the com 

 of Europe where the summers ore hot and dry, and most flourishing 

 in a moist insular climate like our own. This is rendered more 

 intelligible by a comparison of the proportions home by their 

 stouiates, and those of deciduous plants. As far as this subject has 

 been investigated, it appears that their leaves nre usually alto 

 destitute of such organs on the upper side, and that those of the 

 lower ore mostly fewer in number and much less active than in 

 deciduous plants. 



The greater part of Evergreens are raised from seed; some are 

 propagated by cuttings or layers, and the variegated varieties by 

 budding and grafting. The soil in which they succeed best dill, Y, 

 with the kinds; American Evergreens, such as Rhododendrons, 

 Kaluiias, &<x, grow best in equal quantities of peat-earth, sand, and 

 vegetable mould; European sorts grow in their greatest vigour in 

 a fresh hazelly loam, but will thrive in almost any kind of 



The operation of transplanting Evergreens may be performed with 

 success at almost all seasons of the year. Midsumm. r planting has 

 even been recommended ; it however is a work of necessity j 

 than propriety, because its success depends entirely upon the nature 

 of the weather after the operation ; it it )>e cloudy and wet for mime 

 time they may succeed ; but if, on the contrary, it be hot and dry, 

 they are sure to suffer : for this reason, if the pr ',c:iil,.ptcd, 



it is not to be recommended. The Common Holly however has In -n 

 often known to succeed when planted at this season, either for hedge* 

 or as single plants. The hollies iu one very remarkable case were 

 carefully dug up in the cool of the evening, and removed to largo 

 trenches, which hod been prepared for tlicir reception ; a quantity of 

 water was then poured upon the roots, and the soil thrown upon the 

 top of it, which of course was carried down and deposited in all the 

 crevices in the trench, rendering the plants perfectly firm. In the
