Order CCXXXVII. H7^:M0D0RACE^. 
The Blood-root Tribe. 
HiEMODORACE^, R. Browu Prodr. 299. (1810) ; Agardh. Aphor. 170. (1823) ; Ach. Rich. 
Nouv. Eltm. 436. (1828). 
Essential Character. — Calyx and corolla confounded, more or less woolly, superior, 
or inferior. Stamens arising from the sepals and petals, either 3 and opposite the petals, or 
6; awi/im bursting inwardly. Ovary with the cells 1- 2- or many-seeded, superior or 
inferior, usually 3-celled, occasionally 1-celled ; style simple ; stigma undivided. Fruit 
capsular, valvular, seldom indehiscent, somewhat nucamentaceous. Seeds either definite 
and peltate, or indefinite . — Leaves equitant, never fiat. 
Affinities. The principal distinction between these and Amaryllidaceae 
consists in their perianth not having the regular equitant position of sepals and 
petals which is found in the latter, in their constantly equitant leaves, and in 
their flowers, which have frequently a woolly surface, and a small limb com- 
pared with the tube. From Iridacese they are divided by the number of their 
stamens, and by their anthers turning inwards, or, if their stamens are reduced 
to three by those organs being opposite the petals, and by their simple stigma. 
In the first edition of this work I modified the character in conformity to the 
views of Von Martins, who includes Vellozia and Barbacenia. But further 
consideration has led me to confine the order to the plants which are indica- 
ted by Brown in his Prodromus. Mr. Herbert includes all the hexandrous ge- 
nera in Amaryllidacese ; but it seems to me that the characters above given 
are sufficiently well marked to establish this order as firmly as Amaryllidacese 
themselves. As to Wachendorfia, with its triandrous flowers, and superior 
ovary, Mr. Herbert looks upon it as the type of an order (Wachendorfiacese, 
Herb. MSS.) of rare occurrence, but quite unconnected with Hsemodorum and 
Conostylis. Supposing this to be so, still I think it will be better to group 
Hsemodoracese as Brown proposed. 
Geography. Found in North America sparingly, and the Cape of Good 
Hope ; 12 are described chiefly from the more temperate parts of New 
Holland. 
Properties. He CandoUe remarks, that the red colour found in the roots 
of Dilatris tinctoria in North America, where it is used for dying, prevails 
in Hsemodorum and Wachendorfia, and deserves to be studied in the rest of 
the order.
