HYDROPHYLLE^. R. Broivn. 



Calyx inferas, persistens, profunde 5-fidiis, sinubus ssepe appendiculis reflexis 

 auctis. Corolla monopetala, hypogyna, regularis, breviter 5-fida, rotato- 

 campanulata vel rarius subinfundibiiliformis. Starnina 5, perigyna, lobis 

 corollse alternantia, sestivatione inflexa. Jntherce versatiles, biloculares, 

 loculis parallelis longitudinaliter dehiscentibus. Ovarium superum, sim- 

 plex, uniloculare. Stylus elongatus, bifidus. Stigmata 2, terminalia. Pla- 

 centce 2 a dorso liberae vel parietibus adnatse, facie interiore 2 — multi- 

 ovulatae. Fructus capsularis, bivalvatim dehiscens, mine unilocularis, 

 placentis maximis capsulam implentibus, nunc semidissepimentis vix 

 completis subbilocularis. Semina extus reticidata. Albumen copiosum, 

 caitilagineum. Embryo conica, radicula ad hilum spectante. 



Herbse americanae, more Borraginearum hispidae. Folia ssepius lobata, alterna, 

 vel inferiora opposita. Floras in racemis vel spicis unilateralibus scor- 

 pioideo-circinnatis subdichotomis dispositi, vel rarius in axillis foliorum 

 solitarii pedunculati.

Squamce corolUme 5, lineares, dorso adnatie, apice marginibusque liberse. Sta- 

 mina longe exserta. Placentce maximse, dorso liberse, ovarium implentes, 

 2-ovulat8e. 



Folia radicalia numerosa ; caulina pauca alterna lata pinnatim vel palmatim 

 dissecta. Racemi scorpioideo-dichotomi ebracteati. 



1. H. APPENDicuLATUM {Midi. Fl. Bor. Am. i. 134.), foliis infimis pinnatisectis, 



caulinis palmato-lobatis, racemis laxissimis, calycis hispidi sinubus reflexo- 



appendiculatis.

I have received this plant from Mr. Drummond, who gathered it in the
