tlie staminate at flowering time subtended and partly em- 

 braced by a linear deciduous bract of its own length, and 

 bearing 3 — 7 smaller somewhat scarious caducous ones 

 above midway or near the apex: pollen simple. 



In a marshy place near the sea on the south side, above 

 the mouth of Laguna Canon. A gigantic species, and one 

 wdiich will doubtless be found on the mainland southward, 

 whenever our collectors shall cease to pass this genus by as 

 one not meriting their care or notice. These insular plants 

 w^ere not out of flower at the late date of my finding them, 

 namely, the 13th of August; but there was evidence that the 

 mature spike would be an inch at least in thickness.
