alabaster-white in the variety. ‘The ripening of the two is con- 
temporaneous. 
A. eburnea Rydb. has also white berries, but they are ellipsoid, 
9-12 mm. long and 6 mm. wide. A. neglecta Gillman too has 
white (ellipsoid?) berries and has been placed by Prof. Robinson 
as a forma under 4. rubra (Ait.) Willd. with 4. edurnea as its 
synonym. 
Tradescantia ramifera sp. nov. 
Plantae praeter sepala et pedunculos glabrae, pallide virides, 
solitariae vel in fasciculis parvis crescentes. Caules basi erecti vel 
assurgentes, solitarii, geniculati, iterum iterumque ordinatimque 
ramos de omnibus axillis foliorum caulis et postea ramorum emit- 
tentes, 2-4 dm. alti. Folia linearia, involuta, recurvata, 7-9 vel 
interdum 10 mm. lata, basi vaginas glabras, parallelinerves, 1-4 
cm. longas, circum caulem formantia. Bracteae involucri 1 vel 
plerumque 2, involutae, lanceolato-lineares, parte inferiore saltem 
quae 10-12 mm. lata est foliis latiore, recurvatae, glaberrimae. 
Umbellae terminales, sessiles, valde floriferae. Pedunculi 1-2 cm. 
longi, pilis apice glanduliferis dense vestiti. Sepala oblonga, 
viridia, membranoso-marginata, 7-10 mm. longa, pilis apice gland- 
uliferis dense vestita. Petala saturate coerulea, 10-12 mm. longa, 
vel sepalis fere dimidio longiora. Filamenta basi mediocriter 
pilosa. 
Plants glabrous except sepals and pedicels, pale green, solitary 
or growing in small tufts. Stems erect or ascending at the base, 
solitary, geniculate, repeatedly and successively branching from all 
the axils of the leaves on the stem and later on the branches, 2-4 
dm. high. Leaves linear, involutely folded, recurved, 7-9 or some- 
times 10 mm. wide, the bases forming glabrous, parallel-nerved 
sheaths, 1-4 cm. long, around the stem. Involucral bracts 1 or 
usually 2, involutely folded, lanceolate-linear, at least their lower 
part which is 10-12 mm. wide broader than the leaves, recurved, 
perfectly glabrous. Umbels terminal, sessile, many-flowered. 
Pedicels 1-2 cm. long, thickly pilose with gland-tipped hairs, as 
are also the oblong, green, scarious-margined sepals, which are 
7-10 mm. long. Petals deep blue, 10-12 mm. long, or nearly % 
as long as the sepals. Filamenta tolerably pilose at base. 
Belonging to that group of the genus having pedicels and sepals 
pilose with gland-tipped hairs, this species differs from 7. dracteata 
Small which has deep green foliage, with bracts 2-2.8 cm. broad at
