The ailinity is with CaJythrix and Lliotzlcya "vvith similar ovules and 
jDlacentation, while the plant has much the aspect of Calythrix aurea Lindl. 
It dihers from Calythrix and Lhotzkya however, in the complete absence of 
any sepals or calyx-lobes, in the number of petals, and in the sti'ongly 4-ribbed 
calyx-tube which is quite sessile and constricted at the a'pGX, The calyx tube 
is almost that of ActinodiuMy while the bracteoles are those of some species 
of Calythrix.

Although ripe fruits have not been observed, the ovaiy after flowering 
becomes cylindrically elongated with a short constricted portion below the 
summit, but retains the four strong ribs of the llowering calyx-tube. I have 
described the ovules as being 2 in number, and they are the same as those 
which I have seen in specimens of Calythrix and Lhotzhya as far as I have 
examined sj;)eeimens of those genera. These ovules, which are erect near 
the middle of a filiform placenta, appear to be almost or quite separate 
when viewed from one side, but from the 02 :» 2 iosite side they appear to be 
fused to about the middle. It is iiossible that the^^ represent a single lobed 
ovule.
