The tvpe of 'S'. prafensis is in tlie National Herbarium ; and an 

 examination of the i)lentiful material there has led me to the concln- 

 sion that this sjjecies is clearly distinguishable from the more widely- 

 distributed *y. hiapiila Sjn-uce MS. ex K. Sehum. Fl. Bras. Yi. vi. 

 2oO, with which vSehumann confused it {loc. ciL). 



The result of my examination of the material in the National 

 Herl>arium is dis])]ayed briefly in the following systematic account, 

 which includes the description of six new species. The species are 

 arranged as nearly as possible in order of relationship. 



1. Sipanea galioides, sp. nov. S. prafmiiis Oliv. (not of 

 Aul)let) in Trans. Linn. Soc. n. ii. (1886) 27(). Herba gracilis, 

 coiilibus insupcr sa?pe tenuissimis, appresse hirtello-pubescentibus. 

 Folia angusta, linearia vel lineari-lanceolata siepius obtusa sessilia, 

 firme chartacea, utrinrpie subtus tamen densius ])riesertim in venis hir- 

 tella ; stipulce breviuscuhe triangulares acuminata? acutae. FJores 

 1-8 in cymulis capitatis terminalibus dispositi, Cidijcis lobi lineares. 

 acuti ; coroUce tubus gracilis, extus insuper sericeus infra s^pius 

 glabratus, lobi late ovati acutissimi brevissime acuininati, iitrinque

Biitish Guiana : Spelemoota, Am})oo Biver, Koraima, Tm Thurn 



29 ! 1st December, 1884. 



Leaves^ 19-31 mm. X 4-6 mm. ; stipules, ± 4 mm. long. Calyx- 

 lobes 6 mm. Coro//«-tube, 18 mm. oi- longer ; lol)es, 9 mm. x 6*-5 mm. 



Distinct from all the other species in its very narrow, Galium-Wke 

 leaves, and its ample corolla-limb. 



2. Sipanea Spraguei, sp. nov. >S'. acini folia Benth. ex Sprague 

 in Trans. Bot. Soc. Edinb. xxii. 488 (1901), ex ])arte ; Wernham in 

 Kew Bull. 1914, 64. Herba inter humillimas, caulibus tenuibus pro- 

 cund)entibus, in nodis inferioribus radicantibus, infra glabrescentibus 

 ajiices versus minute hirtellis ; folia parva elliptico-lanceolata sub- 

 sessilia sa?pius subobtusa, vix acuminata supra sparsiuscule hirtella 

 nonnuntjuam subglabra, subtus similiter nisi saepius in venis densius 

 induta ; stipulce obsoletaj. Flores sessiles, nisi in ore et faucibus 

 aiu'antiaco-villosi glabri, solitarii caules adscendentes terminantes. 

 Cahfcis lobi erecti lineares acutissimi in corolhe tubum stricte ad})ressi, 

 pro rata breves. CoroUfe tubus gracilis, insui)er parum ampliatus, 

 l<)l)i late obovati apice rotundati, tubi dimidium su]X'rantes. 



Venezuela : Orinoco \i.. Caicara, November 1898, in savanna near 

 a chunp of moriche ])alms, Spraf/uc 7 ! 



Allied to >S'. aciuifolia Sprague ( = S. veris S. Moore), to which 

 I originally assigned it (loc. cit. supra), but it is readily separable 

 from that species in consideration of its much smaller size, smaller 

 leaves, shorter calyx, and relatively much larger corolla-limb. Leaves 

 5-8 nun. x l*5-2'5 mm. C V///.r-lobes 80 mm. Corolla-twha 12 mm. ; 

 lobes 8-0 nnn. X 5*5 mm. 



J^ Sipanea veris S.Moore in Trans. Linn. Soc. ir. iv. 36J^ (1893). 

 /S'. aciuifolia Benth. ex Sprague in Trans. Bot. Soc. Edinb. xxii. 438.
