Ex enumeratione praeeunte Glandinas maderenses maximam affinitatem inter se 
praebere elucet: imprimis Gland. triticea, oryza et tuberculata tantopere inter se affines 
sunt, ut difficillime in species discerni possint. Tamen in tres divisiones arctiores per- 
spicue dilabuntur, quarum primam Gland. maderensis, terebella, gracilis, o^alliformis, Lea- 
cociana; alteram Gland. folliculus, triticea, oryza, tuberculata, tornatellina, melampoides, 
mitriformis; tertiam porro Gland. acicula et producta constituunt.
