VlTIPHYLLUM PARVIFOMUM, Sp. nOV. 

 ri:ito CLXXII, Fi^'s. 11, l'.>. 



Leaves very small, aiTan<,red alternately and rather remotely on ver}- 

 long and proportionally stout petioles, more or less fan-shaped, quite varia- 

 ble in form and size, cut down to near the base into three main lobes, and 

 these subdivided again towards the sunmiit into lobes or teeth, which 

 diverge slightly ; primary nerves three, radiating from the summit of the 

 petiole, the middle one being the strongest, each going into a main lol)e; 

 the primary nerves send off obliquely branches which go into the subordi- 

 nate lobes or teeth. 



Localities : Belt and Covington streets, Baltimore ; rare. 



This is a very peculiar Cissus-like leaf, which in some of its forms is 

 not unlike SynapJuca pohjmorpha R. Br. 



VlTIPHYLLUM MULTIFIDUM, Sp. nov. 

 PKite CLXXIII. Figs. 1-0. 



Leaves small, varj-ing a good deal in size and shape, broadly fan- 

 shaped to subrotundate, more or less heart-shaped at base, cut generally 

 pretty dee[)ly into three principal lobes separated by sinuses that turn 

 slightly outwards ; these in turn are subdivided variously ; in the larger 

 leaves they are cut into subordinate lobes that are like the principal ones, 

 but are cut less deeply ; the larger lobes terminate in shallow lobes or 

 teeth that are mostly bluntly rounded off or emarginate ; primary nerves 

 normally radiating flabellately from near the base of the leaf and going 

 into the principal lobes, the lowest ones being smallest and increasing 

 inwards to the central one, which is the largest ; the primaries sending off 

 obliquely branches on each side which go into the ultimate lobes and teeth; 

 reticulation not seen ; leaf-substance quite thick ; petiole very long and 

 [proportionally quite stout. 



Localities: Belt and Covington streets, Baltimore ; very common. 



This plant is the most common angiosperm at the two Baltimore local- 

 ities. Some of the leaves must have attained proportionally a considerable
