1. P. hastata, Cav, Diss, 138, t. 47,/. 2. A low spreading shrub, more 

 or less hoary, with a minute close stellate touientum. Stipules subulate. 

 Leaves petiolate, from ovate-cordate to oblong-hnstate, obtuse, 1 to 2 in, 

 long, coarsely crenate, scabi'ous above, hoary -tomentose underneath; wdien 

 hastate, the lateral lobes short and obtuse. Pedicels usually shorter than the 

 leaves. Bracteoles 5, ovate, herbaceous, nearly as long as the calyx. Calyx 

 tomentose, 2 to 3 lines long, divided to the micklle into 5 ovate lobes. Petals 

 in the peifect flowers twice as long as the calyx, of a reddish-purple with a 

 dark centre, but in other flowers, equally fertile, they are very small and closed 

 over the stamens, which are then reduced to 5, Avhilst they are much more 

 numerous in the perfect flowers. Carpels obovoid, indehiscent, usunlly pu- 

 heseent, strongly reticulate and with a sliglitly raised dorsal rib.— DC. Prod.
