1. TYPHONIUM, Schott. 



(From typho, to burn, referring to the acrid juice in tbe plant.) 



Spatha contL-aeted above the convolnte'base, the lamina broad, spreading or 

 recurved. Flowers unisexual, the females at the base of tbe spadix, with 

 subulate neutral organs immediately above them, the males separated by a bare 

 interval, the spadix terminating in a long thick fleshy appendage. Perianth 

 none. Anthers 2-celled, sessile in pairs, appearing like 4 1-celled anthers, the 

 cells opening in terminal pores, or in some species in slits continued to the base. 

 Ovary sessile or nearly so, 1-celled, with a single erect ovule; stigma peltate, 

 sessile or shortly stipitate. Berry 1-seeded. Albumen copious. — Herbs with a 

 hard tuberous rhi^^ome. Leaves entire or 3-lobed, radical as well as the scape. 



The genus is generally spread over the warmer regions of the Old World. The Australian 

 species are, as far as known, endemic.

1. T. alismifolium (Alisma-leaved), F. r. M. Fragm. viii. 186 ; Benth. Fl. 

 Austr. vii. 153. A smaller plant than the other Australian species, the tuber

 point and not l-|in. broad in the broadest part. Flowers in the same relative 

 position as in the other Australian species, the terminal appendage rather long. 

 Berry ovoid-globular, about 2 lines diameter.

 6in. to 1ft. long, the lamina divided nearly or sometimes quite to the base into 3 

 narrow or broad lanceolate lobes or segments, the lateral ones horizontally 

 divaricate, 4 to 6in. long, either nearly equal on both sides or more or less 

 dilated at the base on the lower side, the middle lobe usually rather longer and 

 narrower. Scape shorter than the petiole. Spatha ^ith the convolute base 

 ovoid, the lamina 4 to 5in, long, very broad, of a deep purple inside. Female 

 spike at the base of the spadix ovoid, about ^in. long. Neutral organs filiform, 

 recurved. Male spike after a bare interval of about lin. cylindrical, about ^in.
