Question: Pachystegia and Passiflora, are in the family of Passifloraceae?
Context: Passiflora palenquensis is a flowering member of the Passifloraceae family.  It is very closely related to "Passiflora seemannii", which has 2 other close related species.  "Passiflora palenquensis" is restricted to low elevations, usually growing around bases of mountains.  "P. palenquensis" is also related to "Passiflora montana", which is another of the 4 relatively new species originating in Ecuador. Passiflora laurifolia, commonly known as the water lemon, Jamaican honeysuckle, golden bellapple, pomme liane on Martinique & Guadeloupe and orange lilikoi (yellow lilikoi, or simply lilikoi, is the name given to passiflora edulis v. flavicarpa for the valley where it first grew in Hawai'i), is a species in the family Passifloraceae.  It is native to tropical Americas.  The water lemon is an invasive plant in its home region, and has spread to other parts of the world.  As a tropical species, water lemon will not tolerate any frost.  Water lemon is only occasionally cultivated, but the fruits are usually available in markets wherever the vine grows in wild.  It is not yet widely known outside those regions. The passion fruit is the fruit of a number of plants in the "Passiflora" family.  Edible passion fruits can be divided into three main types: purple ones (fruits of "Passiflora edulis" Sims), yellow ones ("Passiflora edulis f. flavicarpa" Deg.) , and giant granadilla ("Passiflora quadrangularis" L.). Passiflora mixta, from the family Passifloraceae is also known as "curuba", "curuba de indio", "curuba de monte", "curubita", "palta" (Colombia), "parcha" (Venezuela), and "tacso" (Ecuador).  Originally, it derived from the monophyletic Adeans "Passiflora" subgenus "Tacsonia".  "Passiflora" includes 47 species, one of which is "Passiflora mixta" which can be found in Southern America.  A perennial vine, the "Passiflora mixta" is pink to orange-red in color. Passiflora bryonioides is a plant in the genus Passiflora, family Passifloraceae.  Common name = "cupped passion flower."  It is native to Arizona, Sonora, Chihuahua, Sinaloa and Guanajuato. Passiflora arbelaezii is a species in the Passifloraceae family native to eastern Nicaragua and western Colombia.  This species was named in honor of Enrique Pérez Arbeláez, the person who collected the type specimen.  It was first formally described in 1957 by Antonio Lorenzo Uribe Uribe. Passiflora montana is a species of plant in the Passifloraceae family.  It is endemic to Ecuador.  This "Passiflora" is related most closely to "Passiflora palenquensis", "Passiflora deltoifolia", and "Passiflora pergrandis". Passiflora lutea (yellow passionflower) is a flowering plant in the family Passifloraceae, native North America, in the eastern and south-central parts of the United States from Pennsylvania west to Kansas, and south to Florida and Texas.  It is the northernmost species of "Passiflora", occurring slightly further north than "P. incarnata", and tolerant of winter temperatures down to −15 °C, and even −30 °C for short periods. Pachystegia is a genus of shrubs in the daisy family described as a genus in 1925. Passiflora, known also as the passion flowers or passion vines, is a genus of about 500 species of flowering plants, the type genus of the family Passifloraceae.
