251 not seen flowers. As the descrirition of the flo\'ver of both species 

 is very incomrilete, and (spart from stating; that the cells have no 

 cell-vrings and the placentas are on the outer v;all) the structure 

 o-f* the fruit is und escribed, its reel, affinity is not certain, but 

 as in general appearance it more nearl^r resembles the .^enus Glotti- 

 tihviium than any othe-' at present knovTi , I nlace it next to that 

 ^enus, ■f'rom vhich the filiform stismas and the presence of stsminodes 

 exclu.'Te it. 



If I am correct In assuminfr (as from, the evidence I have seen 

 T believe I am) th^t the leaves of this plant die away annually, 

 it is the third known c-enus in this p-rour^ of plants that is knovm to 

 be deciduous, or in which the leaves die and v/ither annually, even 

 if they do not fall off, the others being Phyllobolus, W.S.Br., 

 and Dactylopsis, N.E, Br. There are, hoy/ever, also members of the 

 ffenera I-esembr^anthem.um, ^elosperma, Psilocaulon and Sceletium in 

 v/hich the leaves die and persist or are deciduous ajinually; while 

 in one sr^ecies of Amoebophj'-llum they persist as spinos. 



Leaves united at the base on one side for nearly half 



their length, 2-|-4 lines broed, m£.rked with a few pellu- 

 cid dots. 1, retroversum. 



Lea.ves united at the base on one side for not more than 

 one-puarter of their length, about 5 lines broad, marked 

 with some linear blackish lines, 2, Leipoldtii.
