Descr. Entire plant, as flowering at Glasnevin, about 

 eight or ten inches high, growing erect, or nearly so. The 

 main stem is cylindrical, but by no means jointed, it bears 

 a few scattered, articulated flowering branches below, and 

 above, very many horizontal branches, which are again 

 divided, always opposite, brachiate, and with more numer- 

 ous and shorter joints as they come nearer the ultimate 

 divisions: these joints are from half an inch to an inch long, 

 two lines broad, punctated, and at their points are decid- 

 uous hairs in tufts, the ultimate articulation is always ter- 

 minated with a tuft of hairs : the colour is pale glaucous 

 green. The flowers are rather large for the Genus, pale 

 greenish yellow, terminal upon divaricated articulations, as 

 before observed, on the lower part of the stem. Calyx of 

 several small, imbricated scales, which gradually pass into 

 the oblongo-lanceolate, acute petals. Stamens thirty to 

 forty, as long as the petals. Style exserted, a good deal 

 longer than the petals. Stigma quadrifid.
