The following two Nos,, each without either fl. or fr., perhaps 
belong to T'ylophora :— 
Gotunco Atro.—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. 
Gotuneo AttTo.—A widely climbing shrub. In the forests of 
Sobato de Mussengue; May 1856. No. 5997.
