Stigmatophyllum. 517 



2. S. heterophyllum Hooker Bot. Mag. (l 843) t. 401 4. — »Parce pilosum, foliis 

 ovatis obtusis cum mucrone vel subcordatis trilobis, lobis oblongis obtusis, lateralibus 

 patentibus, petiolo infra apicem biglanduloso, umbellis axillaribus plurifloris, stylis apice 

 foliaceis. — A showy, handsome climber, hitherto cultivated in the stove by Mr. Veitch, 

 who raised it from seeds sent from Buenos Ayres by Mr. Tweedie: but I have reason 

 to believe, on the authority of specimens in my herbarium, that its native country is 

 Tucuman, whence the seeds were brought by Mr. Tweedie, and reared by him about 

 Buenos Ayres. It is a ready flowerer, and promise to be worthy of cultivation in 

 every stove or warm greenhouse, making a beautiful object, if trained against trellis 

 work. At Exeter it flowered in December, 1842. 



Descr. Stern branched, climbing. Leaves opposite, mostly ovate, waved, entire, 

 very obtuse with a mucro ; not unfrequently broader, almost cordate, deeply threelobed, 

 the lobes oblong-obtuse, with a mucro, the side ones spreading; colour dark green 

 above, pale below. There are a few scattered, appressed hairs, fixed by their middle, 

 chiefly on the under side of the leaves. Petioles about half or three quarter of an 

 inch long, with a large, depressed gland on either side near the apex. Peduncles soli- 

 tary, axillary, thickened, shorter than the leaf, and bearing an umbel of several rieh 

 yellow flowers. Calyx of 5 erect sepals, each with 2 large glands on the back. Petals 

 orbicular, clawed, waved and ciliated at the margin. Stamens 10. Styles 3, each ex- 

 panding into a foliaeeous, green stigma.« 



Nota. Haec species a S.{$k)littorali Juss. var. ß. trilobo Niedenzu vix differre videtur.
