plant endwise. I have never seen this character mentioned before, 
and do not know how many species share it, but it is certainly not 
the case with all orchids, or even with all spicate ones, as for in- 
stance in Gyrostachys, different species of which have the flowers 
in one, three or four ranks. 
PARONYCHIA HERNIARIOIDES (Michx.) Nutt; Spreng. Syst. 1: 822. 
13g6* 
Collected on the ordinary sand-hills along Big Lott's Creek in 
Bulloch County, June 17 (no. 912), and on the rosemary sand- 
hills of Emanuel County, June 28 (no. 978); also seen on July 3 
in similar situations in Tattnall and Montgomery Counties, espe- 
cially along the left bank of the Little Ocmulgee River at the 
western border of the latter. 
This species has usually been described as prostrate, but incor- 
rectly. Young specimens, like no. 912, have much the habit of 
Anychia dichotoma, while fully developed specimens, such as no. 
978, have the numerous branches very widely speading, making 
the plant considerably broader than high, but they seem to be 
strictly self-supporting, and never show the slightest indication of 
being prostrate. Such a specimen when pressed has very much 
the appearance of Euphorbia cordifolia Ell., a strictly prostrate 
plant, and this is doubtless the cause of the error. 
‘ Cabomba Caroliniana pulcherrima var. nov. 
Stem a meter or more in length, reddish-purple. Submersed 
leaves similar to those of C. Caroliniana, but dark-colored and with 
narrower segments. Peduncles tortuous. Petals bright purple. 
Floating leaves, calyx and fruit nearly as in the species. 
Although further study may show this to be a distinct species, 
the differences at present known seem only to entitle it to varietal 
rank. The purple stem and petals are the most striking features. 
The latter are of exactly the same color as the corolla of Utricu- 
lavia purpurea, for which species our plant might easily be mis- 
taken a short distance away. I find no mention of a purple- 
flowered Cabomba in botanical literature. 
Collected in three or four feet of water in Cane Water Pond,

Genera, but in that work only the name appears, without synonymy or description.
