Very imperfect specimens of a plant found with T. lingulatum at the Bay of Islands by 
myself, have been very doubtfully referred by Mr. Wilson to the European T. sirictum, 
Bruch, (FI. N. Z. ii. 72). The leaves are yellowish, strict, ovate-lauceolate, acuminate, rnu- 
cronate by the thick excurrent uerve, erect or incurved when dry ; the margin flat.
