Question: Which flower belongs to a smaller family, Psilotum or Aphyllanthes?
Context: Downingia pulchella is a species of flowering plant in the bellflower family known by the common names flatface calicoflower and valley calicoflower.  This showy wildflower is endemic to California, where it is a resident of vernal pools and other wet places in the central part of the state from the Tehachapi Mountains to the San Francisco Bay Area.  This annual produces an erect, branching stem which has usually one tubular flower at the top of each branch.  The upper lip of the flower is made up of two narrow, pointed lobes which usually stick straight out and are lavender or white.  The lower lip is the same color and made up of three fused lobes, each of which may have a tooth.  In the center of the lower lip is a large white area with two bright yellow spots and smaller dark purple spots near the mouth of the tube.  A large anther sticks out of the mouth of the flower on a stalk of fused stamens.  The flower is one to two centimeters wide.  The fruit is a capsule three to seven centimeters long. Bryn Avon is a historic estate and national historic district located near Etowah, Henderson County, North Carolina.  Bryn Avon house was built about 1884-1886 and updated in the 1910-1920s in the Tudor Revival style.  It is a 1 1/2-story, stone and half-timbered manor house.  Other contributing resources include the estate landscape and terraced garden and four smaller family cottages: the Mallett Cottage (c. 1925); the Brown house playhouse (c. 1932); Yon Way-the Conrow cottage (c. 1920-1925) and Mr. Conrow's studio (c. 1925-1935); and the Bellamy Cottage (c. 1933-1938). Pogonoloma is a mushroom genus in the family Tricholomataceae in a broad sense.  The genus contains two species known from Europe.  "Pogonoloma" was described first as a subgenus of the genus "Porpoloma" but recent molecular evidence separates the two by several other genera, with "Porpoloma" remaining within a smaller family Tricholomataceae. The punctate flower chafer or spotted flower chafer, Neorrhina punctata, is a species of flower chafer.  The chafers are beetles of subfamily Cetoniinae in the large scarab beetle family (Scarabaeidae).  Among the chafers, "N. punctatum" belongs to the tribe Schizorhinini. Aphyllanthes is a genus of flowering plants with only one species, Aphyllanthes monspeliensis, endemic to the western Mediterranean region.  It is the only genus in the Aphyllanthoideae, a subfamily of the family Asparagaceae.  Aphyllanthoideae was formerly treated as a separate family, Aphyllanthaceae. Old World warblers are a large group of birds formerly grouped together in the bird family Sylviidae.  The family held over 400 species in over 70 genera, and were the source of much taxonomic confusion.  Two families were split out initially, the cisticolas into Cisticolidae and the kinglets into Regulidae.  In the past ten years they have been the subject of much research and many species are now placed into other families, including the Acrocephalidae, Cettiidae, Phylloscopidae, and Megaluridae.  In addition some species have been moved into existing families or have not yet had their placement fully resolved.  A smaller family of warblers, together with some babblers formerly placed in the family Timaliidae and the parrotbills, are retained in a much smaller family Sylviidae. The Zygnematales (Greek: ζυγός ("zygós") and νῆμα ("nḗma") (nom. ), νήματος ("nḗmatos") (gen.)), also called the Conjugatales, are an order of green algae, comprising several thousand different species in two families.  The larger family Zygnemataceae, with well-known genera such as "Zygnema" and "Spirogyra", includes members that grow as unbranched filaments, which grow longer through normal cell division.  The smaller family Mesotaeniaceae includes the saccoderm "desmids", a group of unicellular species that were formerly classified with the "true" desmids.  Most members of both families live in freshwater, and form an important component of the algal scum that grows on or near plants, rocks, and various debris. Psilotum is a genus of fern-like vascular plants, commonly known as whisk ferns.  It is one of two genera in the family Psilotaceae, the other being "Tmesipteris".  Plants in these two genera were once thought to be descended from the earliest surviving vascular plants, but more recent phylogenies place them as basal ferns, as a sister group to Ophioglossales.  They lack true roots and leaves, the stems being the organs containing conducting tissue.  There are only two species in "Psilotum" and a hybrid between the two.  They differ from those in "Tmesipteris" in having stems with many branches and a synangium with three lobes rather than two. Manzanita Sol is a brand of apple-flavored soft drinks owned by PepsiCo and is predominant in Mexico.  In the United States it is sold in 12-pack cans, 2-liter, and 20-ounce bottles.  The drink is known to be available at Walmart, Albertsons, H-E-B, Ralphs, Kmart, Food 4 Less, Jewel-Osco, Dominick's, Target, Vons, Stater Bros., United Supermarkets in the Amarillo and Lubbock, Texas area, and other smaller chains and smaller family run stores.  In Latin American countries, Manzanita Sol will compete with The Coca-Cola Company's Manzana Lift.  Manzanita Sol is PepsiCo's number two brand in Mexico, with apple being Mexico's second most popular soft drink flavor.  It is also very popular in the borderlands such as the El Paso/Juarez border. Psilotaceae is a family of Pteridophyta (in order Psilotales) consisting of two genera, "Psilotum" and "Tmesipteris" with a dozen species.
