LATHYRUS SPLENDENS Kellogg.

“Pride of California,’ distinguished for its profusion of large brilliant rose red to crimson flowers borne in clusters of 10 or more the second year from seed. The most magnificent of the native climbing plants of West America. Described as half-hardy in New Jersey. It stands frost and snows in the mountains of Southern and Lower California, up to 4,000 feet altitude, where it festoons the shrubbery with its wealth of color.

Seed 25 cents a packet, $1 an ounce.

THE STRAWBERRY GUAVA.

The Cattley Guava (Psidium Cattley- anum), better known as the strawberry, is rapidly gaining in popular’ favor throughout Florida and Southern Califor- nia, and has been highly recommended for cultivation in Arizona and New Mexi- co. It is unquestionably the most desira- ble and useful of the many varieties of fruits known under the name of fuava. It is a shrub or small tree that adapts it- self to a dwarfish habit when grown in the ‘house in cold climates, but in a ‘con- genial clime attains a maximum growth

of 15 to 20 feet in height, of compact form,,

and with dense, glossy evergreen foliage, which makes it a very ornamental tree, especially when loaded with its rich col- ored fruit. ria

CACTACEAE.

Many people who have been acquaint- ed only with the prickly pear and the cholla cactus of the plains—perhaps to the detriment of their epidermis, will be surprised to learn that over one thousand valid species exist, to which more than three thousand names have been applied by botanists and _ horti- culturists.

The following is a nearly complete list of known species, and a few syno- nyms are also given. Descriptions of all will be published eventually we hope, but this contains much never published, at least in English, and in this form will be usetul to many.

Tribe ECHINOCACTEAE.

Calyx tube produced beyond the ovary; stem covered with elongated tubercles or ribs, rarely leafy (except when young).

Karl Sehumann, in his monograph, rec-

ognizes 21 genera, including Cereus, Pilo- cereus, Cephalocereus, Phyilocactus, Epi- phyllum, Echinopsis, Echinocereus, Ech- inocactus, Me'’ocactus, and Leuchtenber- gia in this tribe, in the order named, making a separate tribe for Mammillaria, Pelecyphora, and Ariocarpus. Pilocereus, Cephalocereus, Echinopsis, and Echino- cereus are better kept as sections of Cereus; Epiphyllum as a section of Phyl- locactus; Ariocarpus (Anhalonium) as a section of Mammillar’a’ His other gen- era are divided into 3 tribes, Rhipsalidcae, of 3 genera—Pfeiffera, Hariota and Rhip- salis (best treated as one); Opuntieae, of 3 genera—Opuntia, Ncpalea and Pterocac-

tus (the 2 latter of doubtful value); and Peireskieae, including Peireskia and Mai- huenia.

The type of Wat- son’s Mammillaria fvrfuracea was col- lected at Carneros Pass, Ccahuilla (Prin- gle 2580). : A. pulvilligerum I.em, is prismaticum. A. retusum S&S. is prismaticum.

The Cardon is the giant cactus of Lower California and Sonora, where it forms forests, attaining a height of 20 to 35 feet. The ribs are usually 13, and it differs from the giant cactus of Ari- zona (Cereus giganteus) in that the spine bearing areolae on the ribs are connected by wooly grooves. The trunk is often 3 to 4 feet in diameter: the older portions of the branches usually quite thornless. The dead wood is used for fuel, but otherwise this mammoth

production of the desert seems to be without use.

CEREUS THURBERI Engelm.

The Pitahaya Duke is an abundant species in Sonora and portions of Lower California, also said to occur in southern Arizona. It grows from 5 to 20 feet high, many stems 6 to 10 inches in diameter from the same base, oearing greenish or reddish white white flowers followed by large luscious fruit, rather too sweet it is said for northern palates. It was named in honor of George Thurber, a widely re- nowned botanist.

Subgenus PILOCEREUS E. “Tall, cyl- indric, mostly unbranched; upper fiower- bearing portion with more crowded areo- lae and longer, denser, thinner bristles or hairy spines: flowers short: seeds as in Eucereus.’’—F.
