BECCAIU. 



with a large, central, undivided part, the primary sinuses remaining at 



about 80 cm from the apex of the petiole, while at the sides they are 

 only a i'vw centimeters from it; petiole (in one specimen) with quite 

 smooth margins from the base throughout; segments papyraceous, rather 

 brittle, when dry subshining above, slightly paler beneath; transverse 

 veinlets fine and rather sharp; in the leaves of not quite full-grown plants 

 the segments are very deeply bifid and the divisions are elongate, \ery 

 acuminate, but not hanging; the central segments of the leaves of the 

 adult plant are at their point of separation 4.5 cm broad, and diminish 

 from this point very gradually toward the end, which is deeply bifid, 

 the divisions being about 15 to 20 cm long, and apparently not, or only 

 slightly, hanging. Spadices very elongate, triple, or composed of 3, equal, 

 collateral spadices which are quite free from the base and protrude from 

 the same basal spathe; t.he sheath is coriaceous, brittle, of a reddish-brown 

 color, like all the other parts of the spadiz, glabrous and shining, strongly 

 flattened. !) cm broad, with two almost winged edges; the partial spadices 

 are rigid, straight with several rather distant partial inflorescences, and 

 with the undivided axial parts terete, as thick as a finger, tightly sheathed 

 by tubular spathcs, which are quite glabrous, briefly open, expanded at 

 the apex, and terminating with an auriculiform, rather obtuse, or at 

 times shortly bidentate limb. Partial inflorescences divided from near 

 the base into two main branches, these bearing numerous simple floriferous 

 branchlets, of which the lowest are 7 to 8 cm long and the others gradually 

 shorter. The fruit is spherical, 13 to 14 mm in diameter, when nut quite 

 mature.

It is clearly allied to TAvittona rotundifolia and L. microoarpa, but is distin- 

 guished from both by tlie central segments deeply bifid and with the divisions 

 elongated and gradually acuminate. Moreover 1 do not know of any other species 

 of l.irislmiu with three distinct, equal, collateral spadices issuing from the same 

 basal spathe; but then it is not certain whether or not this is accidental, or is 



a constant characteristic of /,. mtndoren$ii. The three flowering axes or partial 



spadices are very similar in their dimensions, branching, color, and spathes to the 

 corresponding parts of the above-mentioned species. The fruits of /,. mindorensia, 



however, are apparently larger than those of /,. iitii-rucurpri, and smaller than 

 those of L. roliiti<iijnliii.
