Dudleya Cymosa Subsp. Marcescens
''Dudleya cymosa'' subsp. ''marcescens'' is a species of summer-deciduous Succulent plant, succulent plant known commonly as the marcescent dudleya or marcescent liveforever. Throughout the months of spring, it is characterized by a bloom of small, bright-yellow flowers with 5 petals, tinged with orange or red. It is a leaf succulent with a basal Rosette (botany), rosette, with the foliage withering in summer, going completely leafless, a Neoteny, neotenous trait in the genus. This species is Endemism, endemic to the exposed volcanic rock of the Santa Monica Mountains in California, being found on shady slopes and outcroppings. It differs from its local congeners with its deciduous habit, slender caudex, and narrower leaf shape, although it is superseded in some of these characteristics by ''Dudleya parva'', growing 13 km to the north, which has even narrower leaves and is quicker to lose them.

Reid Venable Moran
Reid Venable Moran (June 30, 1916 – January 21, 2010) was an American botanist and the curator of botany at the San Diego Natural History Museum from 1957 to 1982. Moran was the world authority on the Crassulaceae, a family of succulent plants, and in particular the genus ''Dudleya'', the subject of his Ph.D. dissertation. He named at least 18 plants new to science — some in that family and some not — and published many papers elucidating relationships within the Crassulaceae. As a mark of the respect he earned among his peers, more than a dozen plants have been named for him. Jane Goodall described Moran as "a sort of living myth in botanical exploration in Baja California and the Pacific Islands of Mexico," citing specifically his analysis of the environmental impact of introduced species (especially goats) on the flora of Guadalupe Island.
