56. Imitation~—We mentioned, § 86, Vol. I., the resemblance of the 
color of a yellow spider to that of the blossom in which it lay im 
wait. Another case of this kind has fallen under our notice. Iti 
well known that in the centre of the white umbel of Daucus carota, 
L., there is generally one dark purple flower. In the latter part of 
July, we frequently found, lurking beneath this flower, a spider of 
very nearly its size and hue. At this season a spider of the same_ 
appearance is found there, but in a web. Perhaps there are two 
kinds of spiders, a web making, and a springing one. The weedis 
very common, and we commend the subject to our entomologists

57. Tetramerism in Lilium auratum, Lindl.—The case of tetramerist | 
in Tradescantia reported by Prof. Martin in the last number of the 
Bulletii leads me to mention a similar instance in the Japan a 
(L. auratum, Lindl.). A plant in my garden has recently produced” 
three flowers all of which were abnormal. as. 
The first flower had but our divisions of the perianth, two outer | 
and two inner, symmetrical and cruciform. The stamens were ony 
four, alike and perfect. The ovary was quadrangular and two-celled, 
with 4 rows of seeds, and the hollow style preserved its quadrilateral | 
character, until expanded into the stigma, which was distinctly” 
trifid or three lined, being the only portion of the flower which 
showed any marks of trimerism. No rudiments of the 5th and 6th - 
stamens could be detected. A 
The second flower had five divisions of the perianth—three outel | 
and two inner—all somewhat twisted or distorted. The nectatr 
ferous portions strictly stellate in arrangement. Stamens 5 onlf 
and no rudiment of 6th visible. One of the 5 a little shorter thal | 
the remainder. In this case the ovary was triangular and thre | 
celled, with the usual three lined stigma. - 
The third and last flower seems in all respects similar to the firsh 
except that one of the four stamens is dwarfed and abortive. a

58. Catalpas.—Your correspondent, Mr. Hall, alludes in the Jw? 
number to catalpas growing wild on Staten Island and in We 
chester Co. I would add that,on the 7th of July, I saw quite 
little grove of them in full flower, at Hohokus, N. J., on the ¥ 
side of the Erie R. R. They grow near, or along, a small broo 
which crosses the road just beyond the station. D. S. Mast.
