num Lantana, and other shrubs, sending up its beautiful 
blue panicles here and there where the thicket was lower 
and less compact. The tubers were about 10 cm. below 
the surface among the network of the roots of the shrubs, 
and very difficult to get at. The tallest plants raised in my 
garden attained 274 m.in 1905, 2°5 m. in 1906, and 2°75 m. 
in 1907. The top panicle flowers first, and is followed by 
numerous lateral panicles developing basewards, until in 
some cases the whole plant represents finally one huge 
compound panicle. At Gerolstein the flowering was, in 
1904, at its best in August. At Kew the plant flowers in 
August, whilst it starts sprouting at the beginning of March. 
_ It is noteworthy that specimens of typical A. Napellus, 
gathered by me at Engstlenalp, Switzerland, and planted 
side by side with the Hifel plants, sprout at the end of 
March, that is 8 to 4 weeks later, and yet commence to 
flower a fortnight before var. eminens has begun. 
Descr.—A herb, often 7 and even over 9 ft. high, 
perfectly glabrous, with the exception of the inflorescences. 
Leaves bright or dark green, somewhat fleshy and glossy, 
the lower long-petioled, reniform-orbiculate in outline, the 
largest 12 in. across, divided like those of the ordinary 
monkshood of gardens; petioles up to 6 in. long. Panicle 
very large and compound, 3-5 ft. long, pyramidal, finely 
adpressedly pubescent in the upper parts ; lower bracts 
like reduced leaves, upper lanceolate, entire, much shorter 
than the pedicels ; bracteoles obleng, obtuse, pubescent, 
close to the flower. Flowers intensely purplish-blue, or 
sometimes purple or variegated. Helmet about an inch 
long, with a broad claw and a depressed hood; lateral 
sepals obliquely orbicular, }-3 in. long, their upper 
margins not contiguous with the helmet. Nectaries with 
a slender claw about # in. long, and a much inclined and 
often exserted hood produced into a 2-lobed lip §-3 in. 
long. Carpels 3, rarely 2 or 4, oblong, erect, glabrous, 
divergent after flowering, but ultimately again erect and 
contiguous. ollicles 1-11 in. long, about + in. wide, the 
tps recurved after dehiscing. Seeds 3-angular, obpyra- 
midal, angles acute, or slightly winged, anticous face 
transversely wrinkled, } in. long.—Orro Srarr.
