verse section, showing three solid and three semi-solid carpels (pseudo-valves); a.t., assimilating 
tissue; f.t., fibro-vascular tissue. 55. Cattleya labiata , ovary in transverse section, structure as in 
Calanthe ; the overlapping of the sunken solid carpels by the pseudo-valves gives a false appearance 
of single-line sutures. 56-7. Triglochin. 56. T. palustre, ovary in transverse section. 57. T. 
marilimum, the same. 58. Hypecoum Geslini, 8-ribbed ovary in cross-section. 59-62. Isatis. 
59. I. hebecarpa, ovary 6-valved. 60. I. littoralis, ovary 10-valved. 61. The same splitting into two 
compound valves. 62. /. iberica, ovary in cross-section ; the orthogonal carpels form four strong 
veins; the smaller veins probably represent an equivalent number of intervening carpels here 
so reduced that they do not form flutings on the surface. (Figs. 52, 53 after Le Maout and Decaisne
