 This is a very peculiar .-Jc«?^j>//r(. It ditfers from all other species which I 

 have seen in its staminal spikes being amenta or catkins. They appear as scaly 

 buds and seem to have been formed at the clos(( of the last growing season. The 

 flowers seem to develop just before the leaves appear. The position of this spe- 

 <*ies iu the genus is doubtful; it is perhaps near A. longipea, which has similar 

 I)edi(els and ovaries iu the female flowers, but the latter has the flowers arranged 

 in ])auicles. 



The plant has much the habit of the hazelnut, and hence the specific name. 



The following note is taken from F. Pax's letter of December 28, 1892: 



"Indeed, it is a very peculiar plant, not allied with any other species of 



Acalypha. There is no. doubt that the ])lant shows the greatest affinity with 



the genus Jcahipha: the flowers are identical with those of Acalypha, but the 



inflorescence is very unlike. I do not know any other species of Acalypha
