356 WILSON EXPEDITION TO CHINA 
flowers (see key, p. 358). On Wilson’s No. 4625 the young fruits show only two 
enlarged sepals, and they differ from the ripe fruits of Henry’s No. 10715” only in 
the size and shape of the smaller three sepals, which are longer-pointed and about 
twice as long as the unripe fruit. Of the ripe fruits I add the following de- 
scription: 
Fructus maturi sepalis scariosis valde inaequalibus circumcincti, olivacei, 
obovato-oblongi, circiter 1-1.2 cm. longi et 0.8 cm. crassi, apice flavo-pilosi, stylo 
sicco aequilongo versus basim piloso et incrassato filiformi coronati. Sepala 2 
(exteriora?) valde elongata oblonga, 6.5-7 cm. longa, fere tota longitudine 1.2-1.5 
em. lata, basi paulo contracta, apice rotundata, utrinque sparse puberula, nervis 5 
distinctis parallelis longitudinaliter percursa, 3 (interiora?) fructu subaequilonga 
apice subito in acumen brevem pilosum contracta; subdenticulata; semen 1, flavo- 
brunneum, a latere compressum, irregulariter subrotundum, circiter 8 mm. latum, 
3-4 mm. crassum. 
Porana triserialis Schneider, n. sp. 
Frutex scandens, ad 5 m. altus; ramuli floriferi herbacei, ut videtur 
flavo-virides, in sicco flavo-brunnei, subteretes v. angulato-compressi 
et saepe contorti, glabri. Folia alterna, membranacea, rotundato- 
ovata, basi profunde lateque cordata, apice satis subito acuminata, 
brevicaudata, margine integra v. pleraque utrinque 1, varius 2 lobulis 
brevibus acutis instructa, supra ut videtur laete viridia, nervis prima- 
riis praecipue 5 e basi palmatim orientibus plus minusve puberulis 
ceterum glabra, subtus paulo pallidiora, tantum ad basim axillis 
nervorum sparse breviter pilosa, 6-10 em. longa (acumine c. 1.5 cm. 
longo incluso), 5-7.5 cm. lata; petioli graciles, 2-4 em. longi, a latere 
compressi, glabri. Inflorescentia axillaris, pedunculo 8-15 em. longo 
parte superiore foliolis paucis cordato-oblongis longe acuminatis ad 
3 cm. longis petiolatis instructo, eymoso-pseudoracemosa, circiter 15- 
flora, ad 10 em. longa, glabra; flores pulehre coerulei, glabri, in- 
fundibuliformes, parte explanata corollae apertae circiter 3-3.5 cm. 
diametiente et circiter 1.8 em. longa, lobis 5 circiter 9 mm. longis 13 
mm. latis rotundis medio apiculatis apiculo piloso, tubo circiter 1.5- 
1.7 em. longo vix 1.5-1.8 mm. erasso ima basi intus piloso; stamina 
5, triserialia, in tubo inclusa, filamentis liberis filiformibus quam 
antherae oblongae subbrevioribus; gynaeceum glabrum, tubo triplo 
brevius, stylo quam ovarium subduplo longiore filiformi stamina ge- 
riei infimae vix attingente, stigmate obovato-oblongo subclavato apice 
emarginato; ovarium ut videtur biloculatum, ovariis 2 sessilibus 
instructum; sepala 5, anguste lanceolata, acuminata, inaequalis, 
longiora ad 8 mm. longa, glabra, nervis 3 subparallelis longitudinaliter 
percursa. Prophylla 2, sepalis proxima, brevioribus valde similia. 
Pedicelli graciles, 8-12 mm. longi, glabri, bracteis linearibus triente 
brevioribus instructi. Fructus adhue ignoti; vide var. lasiam, p- 362.
