Stn 14, one stem, ca. 65 mm high (NIWA 117475); Stn 17, one colony, ca. 32 mm high, on stone (MNCN 2.03/529); Stn 107, a basally truncated stem, ca. 21 mm high (NIWA 117476). Description. Stems up to 65 mm high. Branching sparse (65 mm high stem with four short primary branches, first one giving rise to secondary branch). Many sand grains on skeleton. Pseudohydrothecae curved, each associated with up to four other pseudohydrothecae. No cementing perisarc among pseudohydrothecae. Polyp with distal whorl of eight to ten filiform tentacles. One or two gonophores; when two present, one of them more developed. Cnidome consisting of four categories of nematocysts: microbasic mastigophores, microbasic euryteles (the most abundant), haplonemes and desmonemes (Table 3). Remarks. There is no clear pattern in the arrangement of the ... : Published as part of ÁLVARO L.
