Incarvillea variabilis, Batalin in Act. Hort. Petrop. vol. xii. (1892) p. 177, 
et vol. xiv. (1895) pp. 178, 18>. 
Of the beautiful genus Incarvillea only one species was 
known in 1876, the date of the publication of the third 
part of vol. ii. of the “‘Genera Plantarum;” since which 
time, so great has been the influx of new plants from 
Western China and LHastern Tibet, that Dr. Batalin 
enumerates nine species from Eastern Tibet and China 
alone, in a paper published three years ago in the * Acta” 
of the Imperial Botanical Gardens of St. Petersburg. 
Amongst these is his I. variabilis, a well-named species, of 
which he enumerates 4 varieties, distinguished chiefly by 
the amount of the division of the leaves, and the form of 
their segments. With none of these varieties does the 
plant here figured perfectly accord, whilst approaching 
nearest to var. y fumarizxfolia, itself a protean form in 
foliage as the suite of authentically named specimens in the 
Kew Herbarium demonstrates. From this the plant here 
figured differs in the shorter, more equally pinnate leaves, 
with the leaflets much shorter, broader, and more uniform 
in shape and incision. The curious character of the seti- 
form or horned calyx-lobes, each lobe seated on a large 
tubercle, is common to several species. JI. variabilis is 
remarkable in having no trace of a staminode between 
APRIL Ist, 1899.
