174 XCVII1. ACANTHACEE (CLARKE). { Ruspolia. 
38. RUSPOLIA, Lindau in Ann, Istit. Bot. Rema vi. [1896] 79. 
Anthers 1-celled; otherwise as Hranthemum. 
Monotypic. 
1. R. pseuderanthemoides, Lindau in Ann. [stit. Bot. Roma vi. 
[1896] 80. Shrub; innovations hairy. Leaves up to 3 by 14 in., 
narrowed at either end, hispid, ultimately glabrate, beautifully reticulate- 
veined beneath; petiole up to # in. long. Spikes hardly 1 in. long, 
terminal on lateral branches, subglobose; bracts nearly 4 in. long, 
linear, hispid. Calyx-segments 5, subequal, 4 in. long, subulate, rusty- 
pubescent. Corolla-tube }-1 in. long, linear-cylindric, not inflated at 
the top; lobes 5, subequal, ovate, patent. Stamens 2, not exserted; 
anthers of 1 hemi-ellipsoid cell; filaments glabrous; pollen globose, 
with 3 large stopples, and longitudinal smooth depressions reaching the 
pole. Pistil glabrous; style with 2 small subequal oblong lobes. 
Capsule 1} in. long, stalked, narrow-ellipsoid (all seen are 1-seeded 
with the lower ovule infertile); seeds nearly smooth.—Lindau in Engl. 
& Prantl, Pflanzenfam. Nachtr. zu ii—iv. 307. 
Wile Land. Somaliland: Daua River, Riva, 1418! 
This plant is exceedingly like Eranthemum hypocrateriforme, Lindau makes the 
present genus have “ Rahmen-pollen,” and to thus differ from Eranthemum (which has 
Spangen-pollen ”) and be nearer Graptophyllum. Ruspolia appears to me hardly 
worth separating trom Eranthemum. I see no tangible difference in the pollen. 
39. RUTTYA, Harvey; Benth. et Hook. f. Gen. Pl. ii. 1105. 
Calyx 5-partite nearly to the base ; segments equal, narrowly lanceo- 
late. Corolla with 2 large lips; posticous emarginate ; anticous 3-lobed. 
Stamens 2 (with 2 rudiments); anthers 1-celled, mucronate at the 
base ; pollen subglobose, nearly smooth, stopples 3 large. Ovary and 
style glabrous; branches of the style 2, very small, equal; ovules 2 in 
each cell. Capsule ellipsoid, 4-seeded, long-stalked; seeds without 
hairs, nearly smooth.—Leaves entire. Flowers purple, in short cymes; 
bracts and bracteoles scarcely } in. long, linear. 
Species 2, in East and South Africa, 1 extending to Arabia, 
In this genus the herbaceous petioles disarticulate, leaving small wooden cuplike 
scars. :
