 root sweetly aromatic ; leaves edible like spinach, pleasant, deciduous

This is probably the Asclepiadea mentioned in Welw. Apontam. p. 590, 

 n. 89. 



The following two Nos,, each without either fl. or fr., perhaps 

 belong to Tylophora : — 



GoLUNGO Alto. — A shrub ; stem very tenacious, always green 

 throughout its whole length, twining, used by the negroes for ropes, 

 copiously juicy, not milky ; petioles deeply channelled. In the dense 

 forests of the Queta mountains, never seen to flower ; cultivated at 

 Loanda, April 1858, but not then in fl. The juice is suspected by the 

 negroes, and not without reason, for although watery at first it quickly 

 becomes gummy and very viscid, and on contact with the human skin 

 it dries white and gives off a rather strong ammoniacal odour. No. 4278. 



GoLUNGO Alto.— A widely climbing shrub. In the forests of 

 Sobato de Mussengue ; May 1856. No. 5997.
