abnormal, at any rate they are straight in our plant of Couller?, 
The seeds are reticulate-tuberculate, somewhat irregular in shape, 
and practically the same in both species. 
R. trichocalyx forms a compact mass with erect stems, the leaves 
arethick and more glaucous, divisions fewer and the terminal lobe 
3-toothed. ‘The bud is nearly globular, a little depressed on top, 
‘rather sparsely covered with appressed hispid bristles, and the 
peduncular leaves are often few-parted. The capsule is appressed- 
hispid. 2. ¢richocalyx in amuch greater degree than 2. Coulteri, 
spreads by underground stems which extend 30-40 feet from the 
parent plant in all directions. Along these stems shoots arise at 
intervals, often a half dozen together, forming clumps that in 
time rival the parent. Roots appear to form very slowly and 
these clumps are often of considerable size before any are found. 
‘he shoots even when several feet high are very easily pulled, 
but the subterranean stem promptly sends up a fresh supply in 
the same spot. 
The plant of 2. ¢richocalyx in our garden was installed about 
three years before R. Coultert. In those years it never matured 
seeds, but ever since R. Coulter? was planted beside it, fruits have 
- matured on the side where they touch. &. Coulfert always 
fruits regularly from every shoot.

a package of seeds labeled £. maritima* was purchased from a 
dealer and planted in our garden. Since that time it has been 
allowed to grow spontaneously, but after the spring flowering the 
crown is cut off by the hoe, so that it is practically annual. The 
variations which have appeared are so numerous as to deserve 
recording. The corolla appears to vary least although the extent 
of the rhomboidal spot is very uncertain and a form with fringed 
petals has occurred. The calyptra varies within moderate limits 
but is in general hardly retuse. The stigmas are rarely more 
than four, oftener only two, the longer pair alternate with the 
placentee. These longer stigmas are usually shorter than the 
stamens at the flowering, but in one case my attention being at- 
tracted to the appearance of a plant in which every flower seemed
