TROPICAL AMERTCAX IlUBIACEJi 171 



and probably much larger, witli 20 paii-s of ^^romineiit secondary veins 

 on either side of the midrib ; these are connected by line but con- 

 spicuous veins at right angles ; the stalks of the largest leaves named 

 above are barely 3 cm. long. Inflorescence, +25 cm. X 12 cm. Peta- 

 loid bracts 5-13 cm. x 2-5-6*5 cm., with stalk 3-5 cm. long. Calyx- 

 tube {ovary) 2*5-3 mm. long; lobes 2 mm. X 1*5 mm. Corolla — - 

 lower, cylindrical portion of tube 3*5 mm. long, and over 2 mm. 

 broad ; upper, funnel-shaped portion, 4 mm. long, broadening to over 

 7 mm. in width. The corolla -lobes are almost negligible in length in 

 the mature flower; in breadth they measure about 4 mm.; in fact, 

 these lobes are almost obsolete at maturity, the corolla appearing like 

 a funnel, with an entire rim and a short, eylindric, basal " spout " 

 portion. Filaments exserted over 7 mm., bearing versatile anthers 

 rather longer than 3 mm. The style is exserted somewhat less than 

 the stamens. 



The clavis of the genera, published in No. VII. of this series 

 (Journ. Bot. 1916, p. 322), should be amended by the following 

 additions to include the two genera described above :— 



P. 329, from line 3. Stamens affixed in throat of 

 short corolla, exserted. Flowers in 

 cj^mes. 



Attractive organs of inflorescence modi- 

 fied calyx-lobes Warsceunczia. 



Attractive organs modified bracts Blandihractea. 



P. 331, from line 15. Anthers included ; in- 

 florescence terminal. 



Corolla iml)ricate Fseudoliamelia. 



Corolla contorted. 



Flowers 4-merous JSfeohertiera. 



Flowers 5-meroiLS Bertiera. 



The Genus Sipax'ea. 



This genus, together with its near ally Limnosvpanea, is excep- 

 tional among the Rondeletiese in being herbaceous. It was estab- 

 lished by Aublet (PL Guian. i, 147) in 1775, who described the single 

 species S. pratensis, discovered in Guiana. About a dozen species 

 have been described since, all native in the American tropics, with 

 the exception of S. hispida, which, hke many other Brasilian species, 

 has been found in Paraguay ; K. Schumann, however, in the Flo7^a 

 Brasiliensis (yi. vi. 247 (1S88)), recognizes two, only, beside 

 S. pratensis, namely, S. glomerata H. P. K., and >S'. hiflora Linn. fil. 

 The remainder he includes in aS'. pratensis, with the exception of 

 S, veris, a species collected in Matto Grosso and described by 

 Mr. Spencer Moore in Trans. Linn. Soc. ii. iv. 368 (1893) ; S. ery- 

 thrceoides Cham., which he relegates io Limnosipanea; S. radicans 

 Endl., s}Tionpnous with >S'. hiflora ; and S. carnea Neumann, in Rev. 

 Hort. II. ii. 445 et tab. (1844), which he leaves without mention, 

 possibly because this species was based on a plant grown from seed 

 sent from an unnamed localitv in South America.
