C. STAR OF INDIA (Cripps).—A showy variety, having the free-flowering habit of the Jackmanni type. The leaves are ternate; and the flowers, which are about five inches across, are at first of a reddish plum-colour, changing to violet-purple, the bars in the centre of each of the sepals—four to six in number—being of a Turkey-red, giving the appearance of a central band or stripe. It is a showy variety of considerable merit, and was awarded a First-class Certificate at South Kensington in October, 1867.
