Discussion:

Type. Spelemoota, Arapoo River, 1 Dec 1884, im Thurn 29.

There appear to be two variations within Sipanea galioides, one having both sides of the leaves pubescent as described by Wernham, the other with the leaves glabrous above except for a puberulous midrib and below mainly glabrous on surface with densely strigose lateral nerves and midrib. Corresponding to the first variation showm by the type collection are the specimens cited above of Steyermark 59092 and 60297, Tamayo 2931 and 2769, Lasser 1457 and 1893, Cardona 1846, Tate 288, and McConnell & Quelch 185, whereas the other collections correspond to the second variation having the upper leaf surface glabrous. I am unable, however, to separate these variations clearly. The specimens of Bernard1683 and Steyermark 75281 are doubtfully placed in S. galioides and appear to show some introgression with S. pratensis in having less coriaceous, broader leaves which are less revolute.
