ESCALLONE.E. V. ITEA. CUNONIACE7E. 



Glandular Anopterus. Tree 25 feet. 



Cult. See Escallonia, p. 195. for culture and propagation. 



V. I'TEA (trea, itea, is the Greek name of the willow ; given 

 to this genus on account of the quick growth of the 7. Virgi- 

 nica). Lin. gen. 275. Rich, in Michx. fl. bor. amer. 1. p. 156. 

 Gasrtn. fruct. 3. p. 142. t. 209. f. 4. D. C. prod. 4. p. 6. 

 Diconangia, Michx. gen. p. 5. Adans. fam. 2. p. 165. 

 Cedrela, Lour, but not of Lin. 



LIN. SYST. Pentandria, Monogynia. Calyx regular, perma- 

 nent, campanulate, 5-cleft, with the recesses obtuse, and the 

 teeth subulate. Petals 5, lanceolate-linear, inserted in the upper 

 part of the tube of the calyx, and alternating with its lobes, val- 

 vate in aestivation. Stamens 5, alternating with the petals, and 

 shorter than them ; anthers oblong, rather bifid at the base, 2- 

 celled, bursting lengthwise. Ovarium oblong, free. Style 1, 

 but at length separating into 2 parts : stigma capitate, usually 

 divisible in the furrow. Carpels 2, joined into a 2-celled com- 

 pressed bisulcate capsule, which separate at length from each 

 other from the base to the apex. Seeds numerous, disposed in 

 2 rows along the inflexed margins of the carpels. Shrubs, with 

 alternate simple exstipulate leaves. Flowers racemose, as in 

 Weinm&nnia, but pentandrous, and as it were single styled. 

 The character of the genus is alone taken from 7. Virginica. 



1 I. VIRGI'NICA (Lin. spec. 289.) leaves lanceolate, acutely 

 toothed ; racemes simple, terminal. Fj . H. Native of North 

 America, from Pennsylvania to Carolina. Lam. ill. 1. t. 147.

 t. 9. Sims, bot. mag. 2409. Trew. ehret. t. 98. When this 

 shrub is in vigour it is entirely covered with racemes of white 

 flowers in July and August, and then makes a fine ap- 

 pearance. 



Virginian Itea. Fl. June, Aug. Clt. 1744. Sh. 6 to 7 feet. 



f Asiatic shrubs related to I' tea, and referred to the genus by 

 the authors, but mill probably constitute 2 or 4 different genera 

 rvhen the parts of fructification are properly examined. 



* Leaves alternate. 



21.? UMBELLA'TA (Roxb. fl. ind. 2. p. 419.) leaves alternate, 

 broadly lanceolate, entire, smooth ; panicles axillary and termi- 

 nal, composed of simple umbels, on long peduncles. ^ . S. 

 Native of the Malay Islands. Capsule 1-celled, 2-valved, with 

 2 parietal placentas on each side. Flowers white. 



Umbellate-Qovtered Itea. Shrub 6 to 8 feet. 



31.? MACROPHY'LLA (Wall, in Roxb. fl. ind. 2. p. 419.) leaves 

 alternate, elliptic-ovate, acuminated, callously serrated ; racemes 

 axillary, fasciculate, erect, equal in length to the leaves. Tj . 

 G. Native of the East Indies, on the Khasee mountains bor- 

 dering on the province of Silhet. Flowers yellow, fragrant, 

 when young conical, and valvate in aestivation. Ovarium half 

 adhering to the calyx, 2-celled. Style columnar. 



Long-leaved Itea. Tree 20 feet. 



* Leaves opposite. 



41.? FRA' GRANS (Wall, in Roxb. fl. ind. 2. p. 420.) leaves 

 opposite, cuneate-lanceolate, entire ; racemes terminal ; flowers 

 in sessile fascicles, tetrandrous, and pentandrous. Jj . G. Na- 

 tive of the East Indies, in the Island of Singapore. Flowers 

 yellow, fragrant. Calyx cup-shaped, 4-5-toothed. Petals 4-5, 

 linear, valvate in aestivation, longer than the stamens. Ovarium 

 adnate to the calyx, 2-celled. Style columnar. This species, 

 with the preceding, will perhaps] form a new genus nearly 

 allied to Escallonia. 



/Vagrant-flowered Itea. Shrub 5 to 6 feet. 



51.? ROSMARI'NUS (Roam, et Schultes, syst. 5. p. 408.) 

 leaves opposite, filiform, glabrous, hardish ; peduncles axillary, 

 1-flowered. t? . F. Native of the north of Cochin-china, in 

 sandy places, and in China about Macao. Cedrela Rosmarhius, 

 Lour. coch. p. 160. Calyx somewhat campanulate, 5-toothed, 

 with the base permanent, and the teeth deciduous. Petals 5, 

 obtuse. Stamens 5, equal in length to the petals. Style 1. 

 Capsule 3-celled, 3-valved, dehiscing at the apex, many-seeded. 

 Leaves odoriferous, from containing a quantity of essential 

 cephalic oil. This plant hardly belongs to the order. 



Rosmary-like Itea. Shrub 5 to 6 feet. 



Cult. Itea Virginica is a very pretty hardy shrub, well 

 adapted for decorating the front of a shrubbery. It is increased 

 by layers put down in the autumn. The rest of the species 

 should be grown in pots, in order that they may be protected 

 by a frame in winter, or to be grown against a south wall, where 

 they may be easily preserved from the frost by mats ; a light 

 soil is best suited for them, and they may be either increased by 

 layers put down in the autumn, or by cuttings. 



ORDER CXX. CUNONIA'CE^E (plants agreeing with Cu- 

 nbnia in important characters). R. Br. gen. rem. p. 16. D. Don 

 in edinb. phil. journ. April, 1830. Saxifragaceae, Tribe II. 

 Cunonieae, D. C. prod. 4. p. 7. 



Calyx of many divisions (f. 36. a. f. 37. a. f. 38. a. f. 39. a.), 

 valvate in aestivation. Petals equal in number to the divisions 

 of the calyx (f. 36. b. f. 38. b. f. 39. c.), and alternating with 

 them, imbricate in aestivation, sometimes wanting. Stamens in- 

 serted in a perigynous disk, definite (f. 37. 6.), rarely indefinite ; 

 anthers peltate, 2-celled (f. 38. c. f. 39. a 7 .), bursting length- 

 wise by a double fissure. Ovarium 2-celled : ovula usually in- 

 definite ; styles 2 (f. 36. e. f. 37. d. f. 38. e. f. 39. &.), rarely 

 connate : stigmas 2, simple, obtuse, pruinose. Capsule com- 

 posed of 2 conflated follicles, which are applied to each other, 

 rarely confluent, 2-celled, 2-valved ; for the most part furnished 

 with 2 beaks, and many-seeded ; dissepiments double, from the 

 inflexed edges of the valves. Placenta central, composed of 

 fascicles of umbilical vessels. Seeds pendulous, sometimes 

 winged; testa crustaceous or membranaceous. Albumen copious, 

 fleshy. Embryo slender, straight, with the radicle turned to- 

 wards the umbilicus, usually rather long. Trees or shrubs, for 

 the most part natives of the southern hemisphere. Leaves 

 usually opposite, but sometimes verticillate, simple or compound. 

 Stipulas interpetiolar, rarely wanting. Flowers usually disposed 

 in spicate racemes or panicles. 



The Cunoniacece were first proposed by Dr. R. Brown as a 

 separate family from Saxifragacece, to which they had been re- 

 ferred by Jussieu, and to which they are intimately related, 

 being chiefly distinguished by habit alone. M. Kunth considers 

 them merely as a section of Saxifragacece, but it appears pre- 

 ferable to regard them as a distinct family ; for the advantages 

 arising from dividing extensive families and genera are, that the 

 individuals composing these become better understood, and their 

 characters more accurately investigated. The Saxifragacece are 

 almost exclusively confined to the northern, as Cunoniacece are to 

 the southern hemisphere. Some pass beyond these limits, but 

 their number is very small. Both families agree in having entire
