PELARGONIUM 



which is reduced one- 

 lialf in Pig. 1704, is what 

 is uow known as P. aii- 

 gnlosum. This is one of 

 tlie species which has 

 entered largely into the 

 IVlargoniumsof florists.

 The race is said to l)e 

 derived chiefly tiomP. 



^jS y » losum and P. grandi- 



^/ floriim, but the writer 



can see little evidence 

 of the blood of P. gran- 

 diflorum. It seems 

 to be nearest to P. cu- 

 (XX.) euUatum, having the 



cucullate or disk- 

 shaped not lobed Ivs. and mostly the soft-hairiness of 

 that species. In many of them, however, the leaves are 

 distinctly angle-lohed, suggesting P. angulosum. It is a 

 fair iiuestion whether P. cucullafiim and P. angulosum 

 are thfuiselves to be considered specifically distinct. P. 

 ilnitu-slii-iiin is meant to comprise the whole range of 

 garden forms of the Show or Lady Washington Pelar- 

 goniums. The name will enable one to talk about these 

 garden phiiits with precision. To many of these garden 



P. iliiiiieslirKiii is not the tirst name that has been ap- 

 plied ill tliis group, but the writer is not aware that any 

 rollcctive or group name has been given. Sweet, in 

 particular, has given Latin names to various forms. 

 Thesi' eld names, however, apply to particular histori- 

 cal forms, and it would be violence to enlarge their 

 applicati()n to cover the entire group, and it would be 

 (lillicult to select anyone of them as more applicable, 

 iiiidiT botanical rules, than others. It is also inaccurate

 and branchy, somewhat hairy and glandular: lvs. with 

 stalks 2-4 in. long, cordate-ovate in outline, with 2-3 

 pairs of oblong side lobes (lvs. pinnatifld),. which ex- 

 tend nearly to the midrib and are again toothed and 

 notched: stipules small, 2 pairs at each node: fls. few- 

 several rather small, red or purplish, in umbels and 

 with short pedicels. — A rather common greenhouse 

 plant, the lvs. often with a dark spot.
