This is apparently Gaudichand's E. laiiceolata so far as can be determined 

 from the fragmentary specimen in the Paris i\Iuseum. It is the most striking of 

 all the nnmerons forms ; the flowers are a deep purple, the leaves are broader than 

 in the other varieties.

 at the apex, acute at the base, about 40 cm long, 7 em wide, dark green above 

 and glo.ssy, margin irregularly crenulate, midrib and veins prominent ; petioles 

 about 1 cm long ; racemes about 3 cm long, closely bracteate, stout, deep purple ;

OAIHT : Eastern Manoa ridge dividing Manoa from Palolo Valley, at lower 

 .elevations (1000-1200 feet), flowering May 12, 1918, Rock & Tasartez no. 13312 

 in herbarium College of Hawaii. 



Variety viridiflora is distinguished by the greenish pale flowers and the thick 

 closely bracteate racemes; the leaves stand almost at right angles to the stem, 

 while those of var. typica are re-curved, forming a globose crown ; the racemes are 

 closely packed in the upper part of the stem, while those of var. typica extend 

 along the stem below the crown of leaves. This variety begins flowering very 

 young and the young plants have the leavts narrower lanceolate and purplish 

 beneath : the racemes are fewer flowered and naked.
