| rhodospirillaceae | Phototrophic bacteria isolated from stagnant water and mud. (12 Dec 1998) |
| rhodospirillales | An order of photosynthetic bacteria representing a physiological community of predominantly aquatic bacteria. (12 Dec 1998) |
| Rhodospirillium rubrum | <bacteria> A purple nonsulphur bacterium with a spiral shape, contains the pigment bacteriochlorophyll and under anaerobic conditions photosynthesises using organic compounds as electron donors for the reduction of carbon dioxide. The purple colour results from the presence of carotenoids, though the bacteria are often more red or brown. (23 Aug 1998) |
| rhodospirillum | A genus of gram-negative, spiral bacteria that possesses internal photosynthetic membranes. Its organisms divide by binary fission, are motile by means of polar flagella, and are found in aquatic environments. (12 Dec 1998) |
| rhodospirillum rubrum | Vibrio- to spiral-shaped phototrophic bacteria found in stagnant water and mud exposed to light. (12 Dec 1998) |

| rhomb | 1. <geometry> An equilateral parallelogram, rhombohedron, or quadrilateral figure whose sides are equal and the opposite sides parallel. The angles may be unequal, two being obtuse and two acute, as in the cut, or the angles may be equal, in which case it is usually called a square. 2. <optics> Fresnel's rhomb, a rhomb or oblique parallelopiped of crown or St. Gobain glass so cut that a ray of light entering one of its faces at right angles shall emerge at right angles at the opposite face, after undergoing within the rhomb, at other faces, two reflections. It is used to produce a ray circularly polarized from a plane-polarized ray, or the reverse. Origin: L. Rhombus, Gr. Rhomb, a spinning top, magic wheel, fr. To turn or whirl round, perhaps akin to E. Wrench: cf. F. Rhombe. Cf. Rhombus, Rhumb. (23 Aug 1998) |

| rhombencephalic isthmus | A constriction in the embryonic neural tube delineating the mesencephalon from the rhombencephalon, the anterior portion of the rhombencephalon connecting with the mesencephalon. Synonym: isthmus rhombencephali, isthmus of His. (05 Mar 2000) |
| rhombencephalic tegmentum | The portion of the pons continuous with the mesencephalic tegmentum; it consists of reticular formation, tracts, and cranial nerve nuclei, and forms the dorsal part of the pons (pars dorsalis pontis). Synonym: tegmentum rhombencephali, tegmentum of rhombencephalon. (05 Mar 2000) |
