Marshallia lacinarioides. 



Perennial, somewhat pubescent, 3—4 dm. tall. Stems erect, 

 sparingly branched above, leafy to near top, angled : leaves nu- 

 merous, alternate, basal and those on lower part of stem 10-20 cm. 

 long, with linear or sometimes broadly linear blades, these attenuate 

 at the ends, prominently 3 -nerved, entire, narrowed into margined 

 petioles, other leaves with narrowly linear sessile blades, 1.5-6 

 cm. long, peduncles 5-9 cm. long, slender : heads small, few- 

 flowered : involucres about 5 mm. high : bracts rigid, linear, at- 

 tenuate, winged below the middle : corollas 7-8 mm., long, villous ; 

 segments linear, nearly as long as the tube. 



In the low country, North Carolina to Georgia. 



MarsJiallia lacinarioides makes the fifth species for the genus. 

 It is related to Marshallia graminifolia* but its habit is very sugges- 

 tive of that of some species of Lacinaria, whence the specific name. 

 It may be distinguished by the erect elongated basal leaves with 

 their prominently 3 -nerved blades. The campanulate involucres 

 are about one half the size of those of Marshallia graminifolia and 

 the heads contain but few flowers.

II. THE NORTH AMERICAN SPECIES OF MELOTHRIA. 

 That we have three species of Melothria instead of one in 

 Florida is very evident from material in Mr. Nash's rich collec- 

 tions. So far as I can learn the first and second species following 

 the appended key have never before been described. According 

 to the collector they are native and very plentiful where found.
