tially glabrous, is at the other extreme. The varieties aurea and 
ludoviciana an . acuminata typica are intermediate. e va- 
rieties ludoviciana and alabamensis have the largest flowers. 
Magnolia australis sp. nov. No forms intermediate in pubes- 
cence on the peduncles seem to connect the broad leaved northern 
tree, Magnolia virginiana L., with its glabrous peduncles, and the 
southern tree with relatively narrower leaves and tomentose pe- 
duncles. The tree with the glabrous peduncles occurs as far south 
as Kingsland, Telfair County, Georgia (W.W.A., May 19, 1928), 
within a few miles of the Florida state line. The two forms over- 
lap in their distribution throughout South Carolina and eastern 
Georgia and do not seem to intergrade. i 
The type of the proposed species is from Natchitoches Parish, 
Louisiana. It has silky tomentose-peduncles, canescent twigs, 
large flowers, the petals 8 to 9 cm. long and relatively long leaves. 
e common form in western and southern Florida which has 
prevailingly lanceolate leaves and small flowers, petals often less 
6 long is “Magnolia australis var. parva comb. nov. 
(Magnolia virginiana var. parva Ashe, Bull. Tor. Bot. Club. 55: 
464. 1928.) It is possible that M. glauca B. pumila Nutt (in Am. J. 
Sci. 5: 295. 1822) belongs here. It is described as “leaves ellip- 
tie, acute; a dwarf variety not exceeding 3 feet, growing in east 
orida, where collected by A. Ware.” 
_ “Tilia caroliniana var. latat comb. nov. Tilia caroliniana in 
its typical form is unknown between western Florida and eastern 
and western ranges of this species. It is clearly allied to T. caro- 
liniana and it seems preferable to regard it as a variety of that 
Species.
