Type specimens. Syntypes Breedy and Guzman 2007 : YPM 1553a, b [dry]; MCZ 4123 (722) [dry]. Material examined. 5 lots (see Appendix 1: List of material examined). Designated types not examined. Description. An examination of SBMNH material revealed that colony form (Figure 23A), branch and polyp appearance (Figure 23B) and sclerites (shown here, Figure 24), are comparable with images shown in Breedy and Guzman (2007 : 40-44). Figure 23. Leptogorgia flexilis , SBMNH 422941. A shows colony color, and interesting disposition of branches, with tendency to droop. Colony, gently extended, ~30-40 cm tall B Close up of several branches. Note marked point of branch tip on end of lowest branch. Figure 24. Leptogorgia flexilis , SBMNH 422941, SEM image. Sclerite color deep orange. A Anthocodial sclerite B Sclerites of coenenchyme (last of which may actually be an anthodocial sclerite) C Quadriradiate from coenenchyme. Images match those shown in Breedy and Guzman 2007 (fig. 30). Etymology. The root flexi- is Latin for pliant, bendable, referring to the apparently flexible, droopy, slender branchlets of the live colony. However, Verrill does not give any rationale for the species name. Distribution. Panama, north into lower third of California Bight (off Santa Catalina Island and adjacent California mainland sites). Remarks. Initially, the drooping branches were considered to be more an artifact of preservation and the containers initially used when collected (branches bent downward so specimen would fit in the jar). However, descriptions by others ( Breedy and Guzman 2007 ), indicated that this is a normal branch configuration. Initial preservation in harsh chemicals caused drooping, pliant branchlets to become anything but; now quite brittle and easily broken. SBMNH 422942 is a nice, large colony but badly fragmented due to those early preservation efforts. As well, much of its color has leached out, with any particular branch colored from almost white to tan to pinkish red. Leptogorgia flexilis is an accepted species in the WoRMS Data Base ( Cordeiro et al. 2018c ).
