Sepals yj; in., oblong, scabrous, rigid, persistent after the nutlets have fallen. Corolla- 

 tube in., tubular, scabrous without; lobes very small, ovate. Nutlets 4, T ^ 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. affghanum (viz., Griffith, Kew 

 Distrib. n. 5936) altogether agrees with H. undulatum. 



VAR. suberota ; 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. Mosc. 1869, 330 ?. Scinde, Stocks. The seeds are as in H. undulatum. This 

 was collected by Stocks as part of his n. 473, and is probably a variety of H. undula- 

 tum 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 pedicetted or with leqflike bracts. 



t Stigma elongate conic.
