SEEDS AND PLANTS IMPORTED 



33913 to 34038— Continued. 



on the last day of June, and the last withered on October 24. Not a single day 

 since the commencement of its flowering, a period of nearly four months, has 

 it been without expanded blooms, sometimes 20 to 30, sometimes but a bare 

 half dozen. As in the case with its relatives, the Tigridias, the blossoms only 

 retain their beauty for a day, but they are produced in such rapid succession 

 that their speedy decease is unremarked. How many hundred of flowers my 

 dozen or so bulbs have produced this year I have no idea, but the number has 

 probably exceeded a thousand. The 3-petaled, apricot-yellow blossoms, with 

 the narrow black band bisecting each petal, and the beautiful modeled center, 

 are quite charming; and the knowledge that every day there will be fresh 

 flowers to admire gave the plant an increased value. They made particularly 

 vigorous growth, their flower stems just exceeding 3 feet in height. They are 

 growing in a narrow, raised border facing southwest and backed by a wall. 

 The soil is a mixture of peat, leaf mold, a little loam, and a large propoMion of 

 coarse grit." {S. W. Fitzherbert, Gardeners^ Chronicle, December 3, 1904.)

33998. Philibertella riparia (Decaisne) Stuntz. 



{Sarcostemma riparium Decaisne, in De Candolle, Prodromus, vol. 8, p. 

 540, 1844.) 



Seeds of this asclepiadaceous climber from Brazil were received under the 

 name Pkilibertia riparia (Decaisne) Malme (Bulletin de I'Herbier Boissier, ser. 

 2, vol. 3, p. 63, 1902). Miss Anna Murray Vail has shown (Bulletin, Torrey 

 Botanical Club, vol. 24, p. 305, 1897) that the generic name Philibertia as 

 applied here must be replaced by Philibertella. The plant in question was 

 originally described by Decaisne as Sarcostemma riparium, which is here made 

 the basis of the new combination. Philibertella riparia.
