64 HERBACEOUS PLANTS 



Ord. 47. OLACINEAE are tropical trees and climbers. Couta, Ximenia. 



Ord. 48. ILICINEAE. Holly, Ilex Aquifolium. The wood is used 

 largely by fretworkers and carvers. The juice of Holly bark, boiled and 

 mixed with nut-oil, yields Bird-lime. 



Ord. 50. CELASTRINEAE. The Spindle Trees. Euonymus etiropaeus 

 is indigenous in Oxfordshire. E. latifolia grows in the central walk. 

 Cafka and Elaeodendron are under glass. 



Ord. 53. RHAMNACEAE, or Buckthorn Family, are trees and shrubs 

 represented in various parts of the Garden by Zizyphus, Paliurus (p. 39), 

 Rhamnus (p. 40), Ceanothus (p. 48), and Colletia on the West Wall. 



Ord. 54. AMPELIDACEAE. Two species of Vines may be seen against 

 the West Wall, and are described on p. 45. Ampelopsis quinqnefolia, 

 introduced from N. America in 1629, about the time of the foundation of 

 the Garden, is the familiar Virginia Creeper, an old specimen of which is 

 trained against the Library. In the Stove-house, an allied tribe is repre- 

 sented by Leea micholitzi. 



SAPINDALES 



Ord. 55. SAPINDACEAE. The Soapworts. 



Ord. 56. HIPPOCASTANACEAE. H orse-ches tnuts (p. 47). 



Ord. 57. ACERACEAE. Maples and Sycamores, Acer, Negundo (p. 42). 



Ord. 59. STAPHYLEACEAE. 



Ord. 61. ANACARDIACEAE. Cashew -nuts. Members of this order 

 grow to a large size in the tropics. The genus Rhus, which grows in S. 

 Europe, yields the Sumach dye, R. coriaria', Japanese lacquer, R. verni- 

 dfera ; a tanning principal, R. glabra of N. America. Mere contact with 

 R. toxicodewdron, the Poison Tree, may give rise to "violent inflammation, 

 followed by blisters and ulcers." One of these poisonous shrubs grows 

 near the Mulberry in Plot C. It is wise not to handle the leaves ; indeed, 

 Dr. Church has informed me that an American once wrote to an Oxford 

 journal to protest against the plants being left unguarded ! Kalm states 

 that the allied R. radicans gives out a poisonous exhalation to which 

 certain women are very susceptible, even though they do not approach the 

 plant nearer than a yard. 



Pistacia vera., fruit-kernels, are much used by confectioners ; P. lentiscus 

 yields the Greek resin " Mastic." 



The fruit of the Mango, Mangifera indica, if of the right variety, is 

 among the most delicious of tropical fruits. 



Ord. 63. MORINGEAE. Horse-radish-tree, Moringa pterygosperma. 



Ord. 64. CONNARACEAE. Tropical climbers.
