ing the upper wall so as not to disturb the relations of the base 
of the corolla and the filaments. Then with a small, sharp blade 
cut out from below the remaining upper wall of the ovary, taking 
care to clip off the style and leave it in place to fill the angular 
space which would otherwise be left. Having done this nothing 
is left to stop the lumen of the corolla tube but these filaments. 
If water be now dropped into the corolla it will be found to hold 
perfectly. 
How any considerable quantity of rain which might fall into 
these upright flowers could get out again remains to be found out. 
ut it is not unlikely that it will be found that when a certain 
quantity of water does collect, either by its weight it will bend 
the flower over and escape or by its presence may excite some 
auxotonic movement causing the flower to nod and dump it out. 
A repetition of these experiments should of course be made 
upon newly opened flowers and upon the particular variety here 
described. 
Botanizing in Texas.* II. 
J. REVERCHON. 
In this locality (House Mts.) two entirely new plants were 
discovered, and both have been decorated with the name of Rever- 
choni, a Diplachne and a Campanula. The latter is a little an- 
nual, making long ribbons of the finest blue in the cracks of the 
rocks, with here and there a large tuft of Cereus pectinatus all 
ablaze with its beautiful pink blossoms, or a picturesque cluster 
of Cereus paucispinus covered with brick-red flowers. The more 
noted plants collected here were: on the side of the mountain, 
Metastelma Palmeri, Zexmenia hispida, Cyclanthera dissecta, 
Tpormcea Lindheimeri; on the banks of a sandy creek, Astragalus 
spetocdnlie and a variety of Mentzelia Wrightii with very small 
ower. 
S. 
From House Mt. to Mason is a region mostly sandy or rocky, 
in which three rare plants were collected: Panicum ciliatissimum, 
Brazoria truncata, and Poly pteris Hookeriana. Juglans rupestris 
began to appear along the rocky banks of streams. 
At Mason, a little German town, we resumed our westward 
march. The soil is generally poor, sandy or gravelly, up the 
Llano valley, the plain being covered with mesquit brush. Ata
