sulcatus, C. & M." which has a cylindrical stem and was afterwards 

 recognized by the authors (correctly I think) as being a young con- 

 dition of Lysurus australiensis. The stem is sulcate, pentagonal, 

 as Bailey well names it, and the gleba portion is also strongly fluted. 

 The gleba does not uniformly surround the upper portion of the stem 

 as in other species of Mutinus, but is borne only along the channels 

 with a free line along the edge. This would indicate that the plant 

 is not a Mutinus. but a young Lysurus, and that in a later state the 

 lobes may open out along these lines. There is such a species of 

 Lysurus in China and Japan (Lysurus Mokusin), and our plant has a 

 close resemblance to the original figure of this species. I have ex- 

 amined the Australian specimens very carefully with a hand glass 

 and the upper portion seems to me to be consolidated in one piece, and 

 I do not believe it ever opens in lobes. However, in case it does then 

 our plant becomes Lysurus Mokusin. 



Mr. Bailey has published it as a Mutinus, and as he has observed 

 it growing he would undoubtedly have noticed if it were only the young 

 condition of a Lysurus. 1 He named it Mutinus pentagonus, "referring 

 to the five-angled receptacle.'' Afterwards he found a specimen with 

 six angles which he called Mutinus pentagonus, var. Hardyi. That 

 was only an individual variation, not of any importance in classifica- 

 tion and not worthy of a name, even as a variety. 2 



MUTINUS PAPUASIUS (Fig. 12). I know the plant only from the 

 figure given by Kalchbrenner, which he drew from specimens sent him by 

 Mueller. There are no specimens either at Kew (or Berlin, I judge from 

 Fischer's work) and it is not really known whether the plant is a Mutinus or 

 a Phallus. If a Mutinus it is the most slender species known. 



MUTINUS WATSONL Also a very doubtful species "described" from 

 Australia, but no figure or type material exists. It will probably never be known. 



MUTINUS (?) ANNULATUS (Fig. I2a). This plant is only known from 

 a figure (i2a) published by F. M. Bailey. But one specimen was found which 

 was lost in transit to Kew. The stipe is' white, the gleba-bearing portions "red- 

 ochre" and "annulated." The plant therefore probably belongs to the genus 

 Floccomutinus of Java. 3 



THE GENUS LYSURUS. This genus has a columnal stem 

 bearing free lobes at its apex. The gleba is borne on these lobes. 

 When young the lobes are connivent, and then the plants may be 



'The early stages of Lysurus with the arms connivent have led to some very misleading 

 pictures. Thus Berkeley's original picture of Lysurus Gardneri so misled Professor Fischer 

 that he transferred it to another genus, but after he visited Kew and saw that it misrepresented 

 the plant he should have transferred it back. Our American species Lysurus borealis was 

 named Anthurus borealis, but in my opinion is a Lysurus and I think the same as the Ceylon 

 species. It was originally illustrated with a drawing subject to the same criticism as the 

 original drawing of Lysurus Gardneri. 



8 It is very well established now that the number of arms, or lobes, or angles, or columns, 

 is never constant in any species. 



'Professor McGiuty proposes as its name " Floccomutinus annulatus, (Bailey) McGinty."
