"Growth habit and flower morphology are typical for this species. The leaf petiole, blade and trap exhibit dark maroon to burgundy coloration. Any green coloration has only been noted around the center of the plant in mid-winter. The entire trap, interior and exterior, exhibits dark burgundy coloration throughout the year. Grown under laboratory conditions, where nutrient levels can be comparatively high, the plants still exhibit partial burgundy coloration in the traps and leaf blade."

"A comparison of a conventional sized trap and the [Dionaea ' Big Mouth ' {T.Camilleri}] variety (sic!) which produces large traps on very short leaves."

"these plants produce clumps of rosetted growing points, which result in a mound of densely packed leaves."

"Both (this and [Dionaea ' Dente ' {D'Amato}]) are tissue-cultured mutations. The teeth are numerous, short and jagged, like a beartrap."

"A wild collected [Dionaea muscipula {Soland. ex Ellis}] plant was selected because its marginal spines were noticeably mutated. Instead of being long and filiform (as is usual), the spines of [Dionaea ' Dentate Traps ' {B.Meyers-Rice}] are short and triangular. This feature is not always apparent on small traps, or those produced early in the season, but the traps on mature plants in full growth are unmistakably dentate."

"Both (this and [Dionaea ' Dentate ' {D'Amato}]) are tissue-cultured mutations. The teeth are numerous, short and jagged, like a beartrap."

"A tissue-cultured mutation. The teeth are few anf dused together by "webbing." "

"I crossed [Dionaea ' Dentate Traps ' {B.Meyers-Rice}], (...) with its marginal tentacles mutated into short teeth, with a plant we grow which is noteworthy for its consistently extra large, moderately red- colored traps. This plant was selected from the seedlings. The margins of the trap are dentate like the pollen parent. Like the seed parent, the traps are consistently large, with good coloration. The plant is vigorous and even though the traps do not have normal cilia, they do trap insects."

"(...)The plants varied greatly in trap bar (cilia on leaf margin) size and shape, but one plant in particular was just what I wanted. Because it is red and has trap bars that look like piranha teeth, I named it [Dionaea ' Red Piranha ' {E.Read}]. As with other red Venus Flytraps the intensity of red coloration varies according to cultivation and season. It has been noted by growers who cultivate it next to other popular red Venus Flytraps that its red coloration equals, if not supercedes, their red color."

"The leaves are rosetted all year, with deep red interior traps."

"Distinct from other varieties (sic!) of [Dionaea muscipula {Soland. ex Ellis}] in that all parts of the plant, with the exception of the margins of the traps (see fig. 12), are dark red in colour (RHS 59A). [Dionaea muscipula {Soland. ex Ellis}] produces rosettes of petiolate (<= 85mm long), bi-lobed (<= 26mm long * <= 17 mm high), decumbent to erect leaves, the size of which varies with season. Do not exhibit any physical differences to other [Dionaea muscipula {Soland. ex Ellis}]. Green margins and red inner surfaces of the trap are characteristics common to both [Dionaea ' Royal Red ' {AUPBR 464}] and the normal form of [Dionaea muscipula {Soland. ex Ellis}], and it is the colour of the other plant parts which make [Dionaea ' Royal Red ' {AUPBR 464}] distibctive. Plants in winter dormancy and those grown in conditions of low light may lose some of the red pigmentation (as do most other carnivorous plants), but still retain appreciably more red pigment than typical [Dionaea muscipula {Soland. ex Ellis}]."

"This [Dionaea muscipula {Soland. ex Ellis}] is of uncertain origin, but has been distributed without an established name. As such, the commonly used name [Dionaea ' Sawtooth ' {B.Meyers-Rice}] is being registered. [Dionaea ' Sawtooth ' {B.Meyers-Rice}] is a remarkable plant in the Dionaea Dentate Traps Group {B.Meyers-Rice}. Its marginal trap spines are reduced to small triangular teeth, as in [Dionaea ' Dentate Traps ' {B.Meyers-Rice}]. Unlike that latter cultivar, however, the teeth of [Dionaea ' Sawtooth ' {B.Meyers-Rice}] are frequently minutely divided into two or more tiny teethlets, so the trap has an almost fringed appearance. Late in the season, the interior of the traps may be deeply red, although this is not visible in young traps."
