any Gratioleas, and as well as the form of the coroHa, appear 

 to me to assimilate the plant much more to some of the 

 Salpiglossidea3, and especially to the Salpiglossis prostrata. 

 Hook, et Arn. and some other species from the West Coast of 

 America; which probably form a new genus. Like other 

 Salpiglossidese it comes near the capsular Solaneae, and the 

 corolla is very nearly that of Fabiana. 



The following are the characters of the species I am 

 acquainted with of Aptosimum, and of another genus also 

 from the Cape, which is closely allied to it and belongs 

 likewise to the tribe of Salpiglossideae. 



APTOSIMUM. 



* Folia petiolala, detrita non spinosa. Calycis lacinice intus tomentosce. 



A. eriocephalum (E. Meyer.) ramis prostratis longe lanatis, foliis longe 

 petiolatis ovatis glabris, calycibus lanatis laciniis intus pubescentibus, capsulis vix 

 emarginatis. On the Gariep, Drege. 



2. A. depressum (Burch. supra). 



3. A. indlvisu7n (Burch. Trav. I. 219.) ramis brevissimis, foliis dense 

 CEespitosis oblongo-spathulatis glabris corollas sequantibus, calycis laciniis intus 

 lanatis. — Carroo desert, Drege. Cape Flats, Ecklon. 



Ohlendorffia rosulata. Nees ab Esenbcek. 



** Folia subsessilia nervo medio valido persistente apice demurn spine' 

 scente. Calycis lacinice intus glabree. 



4. A. viscosum herbaceum ? foliis late oblongo-spathulatis viscoso-pube- 

 scentibus nervo medio infra apicem spinescente flores ter superantibus. Rocks 

 near the Gariep, Drege. 



5. A. tragacanthoides (E. Meyer) suffruticosum, foliis anguste oblongis 

 spathulatis glabris flores vix superantibus nervo medio infra apicem spinescente. 

 Rocks on the Kunkunnuroab, Drege. 



6. A. abietinum (Burch. Trav. 1. 308.) suffruticosum, foliis linearibus 

 glabris flore brevioribus nervo medio excurrente spinoso. On the Sunday River 

 and in the vallies of the Kooper hills, Drdge. /3. elongata on the Gariep. 



PELIOSTOMUM. 



Calyx 5-partitus. Corolla et genitalia y^/j/osm^ Capsula ovato-oblonga 

 acuta apice subcompressa sulcata valvulis loculicide dehiscentibus a:pticide bifidis 

 bipartitisve. Semhia numcrosa minuta. — Herbse sufFruticesve rigidae saepe 

 viscosae. Folia omnia alterna integerrima. Flores axillares vel racemosl breviter 

 pedicellati vel sessiles pedicellis ssepe bracteatis. Corolla: forma fere Fabiance.
