believed the whole family to agree in this respect with Biynoniacem, next to which he had placed it ; and he had at least the proof of the absence of albumen in Roxburgh's figure of his Incarvillea parasitica, in which the structure of ovarium as well as of seeds is correctly given.
The genera referred by Dr. Jack to this new family are Cyrtandra of Forster, Didymocarpus of Wallich, and Q07 two other genera for the first time proposed, namely, JEscJiynanthus, to which Roxburgh's Incarvillea parasitica belongs, and Loxonia.
Nearly about the same time Mr. Don published his Didymocarpece} a family consisting of two of Dr. Jack's Cyrtandracece, namely, Didymocarpus and JEschynantJtus (his Trickosporum), and a new genus Lysionotas. He in like manner depends chiefly on placentation, which is not very clearly described; and he also introduces into his character the absence of albumen, the pendulous position of seeds, and the undivided stigma. From this family he excludes Cyrtandra, which has, he states, erroneously how- ever, a copious albumen ; while Chirita of Dr. (Buchanan) Hamilton, of which Dr. Jack's Didymocarpus includes at least one species, is doubtfully referred to Scrophdarince, chiefly on account of its bilamellar stigma.
In 1826 Dr. Blume 1 refers Cyrtandracece to the natural order Bignoniacece, distinguishing it as a tribe from true Bignoniacece by its pendulous seeds, and subdividing it into two sections ; the first, Tric/iosporte, with capsular fruit, and seeds either winged or with some other form of appendage; the second, Cyrtandrece, having baccate fruit and seeds without appendage. To each of these sec- tions he has added more than one new genus, but Loxotis and Loxonia are not included in either of them ; though Loxotis, as I have already stated, is probably his Bhi?icho- glossum, referred by him to Bldnanthece ; and Loxonia, notwithstanding his account of the fruit, may possibly be his Loxopkyllum, which he has placed in Scrophularince ;
