elsewhere, and to be at least as common as four-leaved clovers, 

 or the tri-carpellary walnuts that are occasionally reported. 3 



Among the immediate associates of the Erigenia there was 

 Trillium decumbens Harbison, 4 originally described from DeKalb 

 County, Alabama, which now proves to be rather common in 

 the rich ravines above Tuscaloosa. I did not list that in my 1922 

 paper, though I must have seen it before that time, and perhaps 

 mistook it for a T. Underwoodii that had been stepped on. Dr. 

 Edgar T. Wherry, who has a very keen eye for rarities, pointed 

 it out to me on a visit to the same bluffs on April 7, 1922, and 

 it seems to be a perfectly distinct species. Erythronium ameri- 

 canum, which is seldom seen farther south, was abundant there, 

 but very few of the specimens seem to bloom at any one time. 

 Other associated plants were Trillium lanceolatum, Dentaria 

 laciniata, Saxifraga virginiensis, Aesculus Pavia, and Adelia 

 ligustrina, all in bloom except the last. 



About six weeks later, on April 14, I was exploring another 

 rich ravine about two miles down the river from the locality 

 just mentioned, and found Erigenia again, this time with fruit 

 apparently full grown, though not quite ripe; and I collected a 

 few specimens. Among its associates there (mentioning only the 

 generic name where there is only one species in Alabama) were 

 Liquidambar, Fagus, Aesculus Pavia, A. parviflora, Cercis, Ran- 

 unculus allegheniensis (?), Saxifraga virginiensis, Phlox divaricata, 

 Nemophila, Galium Aparine (apparently native), Dodecatheon 

 Ilugeri, Syndesmon, and Isopyrum; with many other interesting 

 plants farther up the same ravine and in neighboring ones, most 

 of them in bloom at the time, making a wonderful display of 

 spring flowers. 



After the trees leaf out and Nature's great spring flower show 

 is over, the botanist's enthusiasm is apt to wane a little. I had 

 made very few visits to the Warrior River bluffs in summer, but 

 on June 22 of this year I thought I would try to find out what 

 Erigenia looked like at that season. This time I found none of 



3 Two similar instances in other genera may be worth mentioning here. 

 In 1904 (Bull. Torrey Club 31: 23) I reported Chrysobalanus oblongifolius in 

 Coffee County, Georgia, with two or three carpels, although one is the normal 

 number for that family (Drupaceae). Saxifraga is supposed to have two carpels, 

 but in April, 1923, I found three to be the usual number in S. texensis on the 

 Grand Prairie and a few other prairies in Arkansas.
