BASIONYM: Chrysymenia uvaria var. occidentalis Børgesen 1920: 403 , fig. 388 (as Chrysymenia uvaria (L.) J. Ag.).

TYPE LOCALITY: Between St. John and St. Thomas, US Virgin Islands, Lesser Antilles, Caribbean Sea,Western Atlantic.

DISTRIBUTION: From the Carolinas and Bermuda to Brazil, including the Gulf of Mexico and Caribbean Sea ( Ballantine and Aponte 2002, Gavio and Fredericq 2003, Dawes and Mathieson 2008).

SPECIMENS EXAMINED: Caribbean Panama: STRI Beach, Bocas del Toro, LAF-8-31-09-1-18, 9°21’7.02”N, 82°15’19.85”W, in the drift, 31.viii.2009 ( Figs 22–29 View FIGURES 15–22 View FIGURES 23–30 ). SW Gulf of Mexico: Campeche Banks, LAF-NSF-II-30-4 ( WES227 ), 21°06’60”, N 92 °08’66” W, 9.vi.2005, 51–54 m depth; LAF-NSF-II-16-18 ( WES38 ), 22°16’ 020” N, 90°43’230” W, 7.vi.2005, 51–52 m depth. NE Gulf of Mexico : Florida Middle Grounds, FL, LAF-NSF-III-7-4-06- 12-3 ( WES 90 ), 28°10’ 280” N, 84°01’950” W, 4.vii.2006, 41–42 m depth, and LAF-NSF-III-7-4-06-3-10 ( WES67 ), 28°37’260” N, 84°24’380” W, 4.vii.2006, 45 m depth GoogleMaps .

RESULTS: Thalli are rose red to golden-pink, erect, up to 11cm in length, with irregular pseudodichotomous branching ( Figs 23–24 View FIGURES 23–30 ) of the stipe. The main axes and branches are terete, 0.9 to 2.5 mm diam., of solid construction, composed of small pigmented round to oval, cortical cells (5 μm in diameter) gradually increasing in size inward; medullary cells are large, hyaline, ovoid, up to 50 μm wide ( Fig. 25 View FIGURES 23–30 ). The axes and branches bear pyriform vesicles ( Fig. 24 View FIGURES 23–30 ), 3–7 mm long by 3–4.5 mm in diameter. The vesicle walls are 2–(3)–4 cells wide, 66–100–135 μm thick ( Fig. 26 View FIGURES 23–30 ). The cortices of vesicles are complete ( Fig. 27 View FIGURES 23–30 ), uni-to bistratose, pigmented, composed of round to ovoid cells 3–6 μm in diameter, and distal to the larger medullary cells. The medulla is composed of 1–(2) layers of hyaline, polygonal cells, 77–(100–132)–180 μm wide; the outer medulla of intermediate-sized cells. Gland cells are spherical, borne singly, rarely in pairs on unmodified medullary gland-bearing cells ( Figs. 28–29 View FIGURES 23–30 ). Carposporophytes are borne on the vesicles, visible as slightly raised protrusions extending both inwardly and outwardly ( Fig. 30 View FIGURES 23–30 ).
