38. Tristichocalyx. 



This genus has been established by Dr. Mueller, upon suffi- 

 ciently valid grounds, for an Australian plant which had been 

 referred to Pachygone by Mr. Benthara; but the structure of its 

 seed shows that it belongs to a different tribe, the Platygonea, 

 its station being near Cocculus. Dr. Mueller considered that 

 its place was close to Tinomiscium : but it does not bear the 

 slightest analogy with that genus ; in habit it resembles some 

 species of Limacia. Dr. Mueller's description of the fruit and 

 seed is not as clear as might be desired ; but if I understand it 

 rightly, the embryo is imbedded in copious simple albumen, 

 has a superior short terete radicle, with somewhat large, oval, 

 thin, foliaceous cotyledons, which are incumbently curved, with 

 one face directed to the condyle, as in Cocculus ; at least, that 

 is what I understand by his expression " cotyledones latae, te- 

 nerrime membranaceas, sibi applicitse." There is a seed of this 

 plant in the Hookerian herbarium, which has been broken into 

 fragments in the attempt to analyze it : there we find some por- 

 tions of the albumen, which is of a solid waxy consistence ; the 

 radicle is terete, attached to half of one of the cotyledons, the 

 other one being deficient. From this and the broken putamen, 

 assisted by Dr. Mueller's details, I have drawn up the following 

 generic character. 



I may take this opportunity of recommending any botanist 

 desirous of analyzing any Menispermaceous seed to adopt the 

 method I have always successfully followed : — after macerating 

 and freeing the putamen from its pericarpial covering, to intro-
