396 BOTANICAL INFORMATION. 
deal of pains in pressing and drying them. In general I 
have gone over my old ground, where your own former set 
was collected, but I have elsewhere gathered plants which I 
did not meet with before, having made another excursion 
into the sandy country, Guangan. I detected two new 
Eucalypti, allied to your E. macrocarpa (see Icones Plant. 
Tab. 405 and 406), but I believe very distinct. I could only 
judge of them by the leaves and seed-vessels. Of one I 
shall send you capsules, the other was unfortunately lost on 
my way back. I also found two splendid Verticordias, of 
which I transmit specimens. That magnificent species, which 
has its inflorescence in whorls, and of which I communicated 
some account in a former letter (see the present vol. of this 
Journal p. 92), bears flowers that are yellow on their 
first expanding, and, I expect, become ferruginous as they 
advance. I also met.with a very handsome Loudonia, which 
L. flavescens ; it is a much larger plant than 
L. aurea (Lindl.), and throws up numerous flower-stalks to 
the height of five or six feet, with sulphur-coloured 
flowers; but the seed-vessels are almost white. It grew in 
a spot which appears to have been formely a lake. L. aurea 
scarcely produces any mature seed. Z. flavescens perfects 
seeds in abundance. 
* I have detected, this season, a very remarkable aquatic 
of the Alismacee family, of which the expanded flowers are 
three igches in diameter, snowy white, with a crimson 
eye; the scent like that of Nelwmbium speciosum. It is an 
annual, and grows in pools of water which become dry in 
summer. The leaves resemble those of our English Alisma 
Plantago, seven or eight inches long by two broad, and 
float on the surface of the water where it is two or three 
feet deep. But the remarkable circumstance connected with 
this plant is, that it bears, even while the plant is smali, 
abundance of what appear to be fruit-stalks, sometimes two 
inches in circumference, which never reach the surface of 
the water, nor ever expand into a flower. They are 
terminated by what I consider seed-vessels, a sort of pouch,
