Seed development and germination
This article is meant for plant physiologists, molecular biologists, biochemists, biotechnologists, geneticists, horticulturalists, agromnomists and botanists, and upper-level undergraduate and graduate scholars in those disciplines. It integrates advances within the varied and rapidly-expanding box of seed technology, from ecological and demographic facets of seed construction, dispersal and germination, to the molecular biology of seed improvement.

The description, culture, and uses of these cacti are so varied that they must be discussed separately under each sublribe and genus. Til_ Torm C"efi-TIte Subtrlb.

But the whitespined species should be given somewhat less water than lhe others. Perhaps the most striking flowers among the Slender Torches belong to the genus Helioeereus (hee'-Iee-oh-see'-ree-us). mbering lropical plants, native to Mexico and Cenlral America, whose spectacular day-bloommg flowers arc considered by many the finest in the Cactus family. The Sun Cereus, H . speoiosus1 is perhaps the best-known species. Its magnificent scarlet flowers have been extensively crossed with the epiphyllums to give us the so-called Orchid Cacu, or modern hybrid epiphyllums.
Will not take temperatures much below 50·F. To conclude this list of Slender Torch Cacti we must add those almost vinelike plants of prolific blooming habn that make up the genus Eriocereus (ehr-ee-oh-see'-ree-us). They are stTOng-growing cacti requinng rather large pots. rich soil. and abundant watering, and can take temperatures to 20·F. E. bonplandii, with huge white night flowers from spring until late faU, is probably the best-loved variety. BUI the Pink Moon Cactus, E. regelii, wilh very similar pink blooms, is a close rival.
