secondary very indistinct. Petiole not half the length of the blade, slender. Svathe 

 yellow-green. Seed \ in. long, linear-oblong. 



13. A. costatum, N. E. Br. in Gard. Ghron. 1892, i. 426; leaves 

 4-5 in. ovate acute or cuspidate, blotched with white base retuse or sub- 

 cordate, primary nerves 7-9 pairs spreading and strongly arched, petiole 

 stout, shorter than the blade, peduncle stout, spathe 1 in. obovoid, spadix 

 protruding. 



Peeak, Oartis (Bort. Veitch). 



Leaves 2i-3 in. broad, dark green, costa stout, base rather unequal-sided; 

 petiole ij in. diam., terete, sheath basal. S^pa^Ae light green, subacute. Spadix very 

 large, the protruding male part f in. long, i in. diam. 



21. KOnXAIiODIEMA, Schott. 

 Herbs, rhizome stout or 0. Leaves e ntire very variable in shape. Spathe 

 usually erect, convolute, wholly persistent round the fruit. Spadix in- 

 cluded ; male and fem. infl. close together, cylindric ; ovaries with or 

 without clavate staminodea. Stamens distinct, in dense groups ; anther- 

 cells very short or oblong opening by pores or slits; connective thick. 

 Ovaries ovoid or globose, perfectly or imperfectly 2-4-celled, stigma sessile ; 

 ovules 2-seriate or the placentas, anatropous or ^-anatropous. Berries few- 

 or many-seeded. Seeds small, ovoid, albuminous. Embryo axile. — Species 

 about 30, tropical. 



Chamcecladon, as constituted by Schott, cannot (as Mr. N. E. Brown had 

 previously observed) be separated from Somalomena by the ovarian cells, or by any 

 other character. A more natural generic division of the species of both would be 

 into those with the spathe contracted above the fem. infl. and those with no such 

 contraction ; and I have adopted this as a sectional character. The further group- 

 ing of the species here described is artificial, and not very reliable, it is the best I 

 could devise from Herbarium and often hardly sufficient specimens. H. rostrata 

 differs from the generic character in having a vacant space in the spadix between 

 the male and fem. infl.

1. K. sagrittsefolia, Jungh. ex Schott Prodr. 311 ; leaves ovately 

 or deltoidly sagittate acuminate not much longer than broad, basal lobes 

 usually spreading, sinus rounded at the base, spathes many 3-4 in. long, 

 tube much shorter than the limb. Miq. Fl. Ind. Bat. iii. 212; Engler

Robust (stemless, Scortech.). Leaves 8-14 by 6-10 in., firm; lobes rarely 

 conniving, sinus broad or narrow; nerves rather strong ; petiole 1-li ft., sheathing 

 to the middle. Peduncle 6-9 in. Tvie o/ spathe 1-li in., limb 2-3 in. by 1 broad, 

 white pink when young. Spadix stipitate. Male infl. 3 in. by i in. diam., fem.

 Descript. chiefly from notes by Scortechini. 



2. K. paludosa, Mooh. f. ; leaves oblong-hastate usually twice as 

 long as broad acuminate, basal lobes divaricate obtuse or rounded, sinus 

 broad rather deep, base rounded, spathes numerous 3-4 in., tube as long 



as the limb.
