Plant 2 dm. long or longer; branches linear, 5 to 8 cm. long, i to 2 cm. broad, with serrate margins; flower-bud elongated, cur\'ed upward, pointed; tube of the flower about i cm. long, the segments 8 (rarely 9), magenta, about 3 cm. long, the outer 4 or 5 spreading or cur\^ed backward, linear, the inner 3 or 4 broader and more erect; stamens 10 to 12, slightly exserted, borne in 2 series at top of tube; style slender, purple; stigma-lobes 4, white; ovar}^ short-oblong, green, somewhat tubercled, with a few areoles subtended by small ovate scales; fruit ovoid, cm. long, turgid, wine-colored. Type locality: Honduras. The species described from a garden specimen, introduced into England in Fig. 205.—Disocactus eichlamii. Distribution: Honduras and Guatemala. We have had this plant under obser\-ation for a number of years. It is rather a shy- bloomer with us, although we get one or two flowers each spring; the fiowers open in the night or early morning and remain open all day; they begin to wither the second morning. The perianth-segments are more widely spreading in the morning than in the afternoon. The flower is almost horizontal and the tube proper is about the length of the ovary. The fruit matures very slo\vly. In 1920 we had a plant flower in April, but the fruit did
