Sepal is in., oblong, scabrous, rigid, persistent after the nutlets have fallen. Corolla- 
tube $ in., tubular, scabrous without; lobes very small, ovate. Nutlets 4, 4. in., ver- 
rucose or bristly.—Boissier says that H. affghanum has the corolla hairy within, and 
thus differs from H. undulatum, but the type of H. affyhanum (viz., Griffith, Kew 
Distrib. n. 5936) altogether agrees with H. undulatum. 
Van. suberosa ; fruits depressed-globose } in. diam. glabrous dividing into 2 two- 
seeded nutlets with corky cells on the back. H. nubicum, Bunge in Bull. Soc, Imp. 
Nat. Mose. 1869, 330 ?.—Scinde, Stocks. The seeds are as in A. undulatum. This 
was collected by Stocks as part of his n. 473, and is probably a variety of H. undula- 
twm affected by an insect-punctures; but it is remarkable that Stocks’ example has 
very numerous flowers and fruits, and that every ovary, without exception, appears to 
form a corky fruit. 
*** Leaves small or very narrow, subentire, scabrous hairy; flowers mostly 
bracteate, lower often pedicelled or with leaflike bracts. <
