8. C. LJEVIGA'TA Willd. The glabrous-leaved Celtis, or Nettle Tree. 



Identification. Willd. Enum. Suppl., p. 68. ; Willd. Baumz., p. 81. ; Rcem. et Schult. Syst. Veg., 

 6. p. 306. 



Synonyine. Sprengcl has suggested, in the Index to his Syst. Veg., that glabrata is the epithet fitter 

 for this species than lavig^ta : glabrata signifies rendered, or become, bald ; l&oigata, rendered 

 perfectly even in surface. 



Spec. Char.,(C. Leaves ovate-lanceolate, subcordate at the base, nearly entire ; glabrous on the 

 upper surface ; roughish upon the veins on the under one. ( Willd. Enum. Suppl.) In lloem. et 

 Schult Syst. Veg., a somewhat different specific character is quoted from Willd. Wild. Baumz., 

 p. 81., the following : Leaves ovate, acuminate, subcordate at the base, unequal there, nearly 

 entire, glabrous on both surfaces. Additionally to the specific character, it is stated as follows : 

 It is a large tree. Its leaves have 1 2 teeth at the tip. It is a native of Louisiana. To this kind 

 seems to belong that Ctiltis named C. americana, or Micocoulierde la Louisiana, cultivated in the 

 Paris Garden, which Poiret, in Encycl. Suppl., 3. p. 668., No. 10., has noticed to have its leave? 

 membranous, rough on both surfaces, yet nearly glabrous ; with the base with one side shorter 

 than the other, and narrower, and some leaves almost falcate. 



& 9. C. PU X MILA Ph. The dwarf Celtis, or Nettle Tree. 



Identification. Pursh Fl. Amer. Sept., 1. p. 200. ; Roam, et Schult. Syst. Veg., 6. p. 307. 



Spec. Char., $c. A small straggling bush. Leaves ovate, acuminate, serrate with equal teeth ; 

 unequal at the base; downy while young, afterwards nearly glabrous on both surfaces. Flowers 

 3 upon a peduncle. Fruit solitary, ovate, black. Indigenous to the banks of rivers in Maryland 

 and Virginia, where it flowers in May. Pursh has seen the kind alive. (Pursh Fl. A. S.) The 

 plant was introduced by Lyon in 1812; and the name is in Loddiges's Catalogue, ed. 1836; but we 

 have not seen the plant there or elsewhere. 



App. i. Species of Celtis half-hardy^ or not yet introduced. 



C. orienthlis Lin., R. Mai , 4. t. 40., and our fig. 1255., is 

 a native of the Himalayas, introduced in 1820. In foliage it 

 resembles C. occidentals ; but we have only seen a very 

 small plant of it, against a wall, in the Horticultural So. 

 ciety's Garden. In p. 174., five Himalayan species are 

 enumerated as likely to prove hardy or half-hardy ; but 

 none of them are yet introduced. In the Hortus Britan- 

 nicus three species are enumerated as indigenous to Ja- 

 maica, and as, in Britain, requiring the stove ; but, as C. 

 orientalis is also designated as a stove tree in catalogues, 

 it is possible that the Jamaica species may be equally 

 hardy. In the Himalayas, Royle observes, the genus 

 C*ltis occurs at considerable elevations, and as far north 

 as Cashmere. C. orientalis Wall., which we suppose to 

 be identical with C. orientalis Lin., "and species allied to 

 it, occur in the hottest places ; C. tetrandra Roxb. extends 

 along the foot of the mountains as far as Cashmere." C. 

 alj/ina Royle was found by Mr. Royle on Urrutka, nearly 

 at the greatest elevation, and if it were introduced would, 

 doubtless, be hardy in the climate of London. C. Ingldsii 

 Royle occurs in Kunawur ; and is, doubtless, equally hardy 

 with C. alplna As the seeds of Celtis go in little bulk, 

 and retain their vital energies for at least a year, there 

 will be little difficulty, we think, in getting these species 

 introduced into Britain. 



CHAP. CII. 



Of THE HARDY LIGNEOUS PLANTS OF THE ORDER JUGLANDA^EJE. 



THE hardy ligneous plants of this order are included in the genera named 

 and characterised as under: 



/U V GLANS L. Flowers unisexual ; those of both sexes upon one plant. 

 Male. Flowers in cylindrical, drooping, solitary catkins ; many in a catkin : 

 the catkins developed from buds borne by shoots produced previously to 

 the year in which the "catkins appear. Calyx of 5 6 scales, that are 

 attached to a bractea at a distance from its base and tip. (Is the flower 

 stalked, and connate with the bractea?) Stamens 18 36. Female. Flowers 

 solitary, or a few in a group, terminal upon a shoot developed in the same 

 year. Calyx ovate, including and adhering to the ovary, except in the 

 4-toothed tip. Petals 4, small, inserted into the free part of the calyx. 

 Ovary of one cell, and one erect ovule. Stigmas 2 3, fleshy, scaly with
