The principal figures were drawn by Mr. P. Roetter, the analyses by the author. 
— While this article is going through the press I have an ——— to examine the true Antephora as Stendel, 
or sacuias as the author, Schreber, writes it. The 4-5-flowered head of spicule has certainly a very great resemblance 
the female heads of Buchloé; there are the same exterior indurated glumes, forming together an involucrum, the same subulate 
glumes towards the centre of the head, and the pale of the fertile flower have the same direction, the lower one towards the 
centre, and the upper one towards the outside of the head. But the outer iaichea? leaf is the lower glume (as Kunth, Agrost. 
i. 169, and Endl. Gen. p. 85, have it; while Steudel, Glum. i. p. 111, calls it less correctly an involucrum), the inner is the 
the head, and towards the inside the fertile chartaceous flower; the analogy, therefore, is a a one only ; but it is 
interesting to observe here again, as so often elsewhere, how different organs may assume the same and the 
functions. The specimen examined is No. 2533 of Fendler’s Venezuela Collection.
