St. Petersb. vi. ser. 1i. 130. 2. 2, quz ad Spéream relata est a 'Torrey et Gray, a congeneribus differt, 
precipue filamentis basi coalitis, et habitu saxifragoideo foliis palmatilobatis. 
In S. parvifolia, Benth., specie admodum singulari, calycis tubus obconicus est, lobis exacte val- 
vatis, ovulis 2 collateraliter pendulis, semine solitario lineari terete, testa molli vasibus tenuissimis 
fareta, et embryone strato tenui albuminis donato. Semina j.aricfolie aliarumque specierum 
denuo examinanda sunt, 8i forte albuminosa evadant.
