CASE which are eaten when young. The fruits are also pickled 



31. and the seeds yield a clear limpid oil. In India the root 

 is accepted by Europeans as a perfect substitute for 

 horse-radish ; it also used medicinally as a vesicant. The 

 stem affords a reddish gum used in calico-printing and 

 in native medicine. 



Observe pods and winged seeds of Moringa concanensis^ 

 Nimmo, also those of M. aptera, Gaertn., the seeds of 

 which are not winged. The latter species is found in 

 Abyssinia, Upper Egypt, Syria, and Arabia, and the seeds 

 are supposed to have yielded true Oil of Ben. 



CASE Connarus Order (Gonnaraceae). A group of erect 



32. or climbing shrubs or trees. Natives of tropical 

 countries. 



Note Cattle-ropes, made of twisted stems of Rourea 

 santaloides, W. and A., and Connarus monocarpus^ L., 

 used in Ceylon. Also specimens of Zebra Wood, an 

 ornamental hard wood of British Guiana used for 

 inlaying, furnished by Connarus guianensis^ Lamb. 

 \_Omphalobmm Lambertii, DC.]. 



Leguminous Order (Leguminosae). The specimens 

 and products illustrating this great order extend from 

 Case 32 to Case 47. The species number about 6,000 to 

 7,000. They are herbs, shrubs, or trees, and are widely 

 distributed over the surface of the globe. One division 

 of the order is marked by the curious form of the flower, 

 the petals being unequal in size and disposed in a form 

 which has suggested the name Papilionaceous^ or butter- 

 fly-like. The fruit is commonly a pod (legume) more or 

 less resembling that of the Bean or Pea. Many species 

 are natives of Britain (Broom, Whin, Clover, &c.), and 

 large numbers are cultivated, both as important food-plants 

 (Peas, &c.), and for ornament (Acacias, Laburnum, Lupin, 

 &c.)- This large order is sub-divided into three sub- 

 orders. 



Sub-Order I. Papilionaceae. On the middle shelf 

 of the first division of this case are samples of leaves of 

 two species of Cyclopia used as tea in South Africa, 

 namely C. genistoides, Vent., en lied Honigthee, and C. 

 suhternata^ Vog., Cape or Bush Tea, also Borhorda 

 •Toarviflora^ Lam., known as Stekelthee.
