of the flowers, which Nicholson describes as white, from 
typical Cuulteri. Mr. W. E. Gumbleton, who grows them 
side by side, informs us that Coulteri differs only in the 
colour of the flowers from the form commonly cultivated 
under the name of mexicanus. Neither Koehne nor Schneider 
was clear as to the identity of P. Coulteri. 
Drscriprion.—Shrub, 3-6 ft. high, glabrescent, very free- 
flowering. Branches slender, red when young, primaries 
elongated, secondaries lateral, very short, usually 1-flowered. 
Leaves very shortly stalked, papery, ovate, }—2 in. long on 
the flowering branches, larger on the leafy shoots, apiculate, 
rounded at the base, entire or furnished with one tooth on 
each side, at first sparsely furnished with appressed hairs. 
Flowers solitary, terminal on very short lateral shoots of the 
main, long branches. Calyx lobes 4, ovate, about } in. long, 
acuminate, 3-nerved, puberulous outside, tomentose inside, 
white. Petals 4, ovate-rotundate, 4-2 in. long, glabrous or 
furnished with a few scattered hairs on the outside, white 
with a bright purple-red base. Stamens very numerous; 
anthers yellow. Styles and top of ovary glabrous; stigmas 
capitate—W. Borrina Hems.ey. 
Cuitivation.—The plant here figured is a very distinct 
addition to the hardy sorts of Philadelphus. The fine 
purple blotch which stains the base of each petal gives a 
colour effect which is lacking in the other hardy species, all 
of which have pure or nearly pure white flowers. Judging 
by the young plants in the Kew collection it appears to be 
of low or medium habit. A mode of cultivation which 
answers exceedingly well for Philadelphus Lemoinei at Kew 
may be adopted for this plant also. This is to cut away the 
shoots that have flowered as soon as the blossoms are over, 
thus leaving behind nothing but the young growths of the 
current year. These grow quickly and make long flowering 
shoots for the following year, to be cut away in their turn. 
Propagation is most readily effected by cuttings made of the 
young shoots whilst they are still in a semi-herbaceous 
condition. Placed in a brisk bottom-heat they strike root 
in a few days. The plant from which the figure was 
prepared was purchased from Messrs. Veitch in 1905,— 
W. J. Brean.
