72 NOTES ON THE ACANTHACEAE OF JAVA Rostdlularia magnifolia Brem. n. spec.;typus: BÜNNEMEYER 12587 L; maxime ut R. bonthainensis Brem., sed spicis angustis laxioribus, -foliis majoribus, bracteis bracteolisque minoribus ab ea faciliter distinguenda. Herba ramosa robustior. Rami internodiis primum bisulcatis 4-12 cm longis et 1-2.5 mm diam., primum densius hirsuti, deinde plus minusve glabrescentes. Folia petiolo hirsuto 2-9 mm longo instructa; lamina lanceolato-elliptiea, 2-11 cm longa et 0.9-3.7 cm Iata, utroque extremo acuta, margine indistincte crenata, herbacea, supra hirsuta, subtus pilis brevioribus praesertim costa nervisque pubescens, cystolithis subtus inconspieuis, supra irregulariter sparsis, siec. nigrescentibus, nervis utroque latere costae 3-10, utraque facie prominuUs. Spicae pedunculo usque ad 5 cm longe instructae, rachide pubescente usque ad 8 cm longa, ex internodiis 3-7 mm longis composita; spica 7 mm diam. Bracteae calyci plerumque subaequilongae, infimae interdum breviores, omnes ovato-lanceolatae, 4-5 mm longae et 1.2-1.7 mm latae, acutae, apieem versus contractae et conduplicatae, margine et costa carinata pilis tenuioribus densius ciliatae, late hyalino-marginatae. Bracteolae lanceolatae, 3-4 mm longae et 0.8--0.9 mm latae, ceterum ut bracteae. Calyx 4-partitus; lobi in tubum 0.4 mm altum connati, aequilongi, 3.7--4.0 mm longi et 0.8-1.0 mm lati, ceterum ut bracteae bracteolaeque. Corolla 8.5 mm longa, extus glabra, labio inferiore tamen ad apicem hirtello, tubo faucibus 0.6 mm longis comprehensis 3.3 mm longo, labio superiore apice latius truncato, vix emarginato, lobis labii inferioris 0.5 mm longis, rotundatis. Stamina filamentis 3.4 longis; thecae inaequilongae, superior 0.6 mm, inferior 0.7mm longa, inferior calcare vix 0.2 -mm longe instructa; connectivum 0.3 mm latum. Granula pollinis 27 ft longa, 17 ft Iata, 13 ft crassa. Ovarium glabrum, 1.2 mm altum. Stylus basi hirtellus 6 mm longus. CapsuIa glabra vel apiee pilis perpaucis instructa, 6 mm longa et 1.7 mm Iata, parte solida 2 mm longa. Semina carunculata. Habitat terrae Celebieae partem austro-ocddentalem. S.W. Celebes. Ravolo, alt. 900 m, BÜNNEMEYER 12587L, typus, H. VI. This species is easily recognizable by the comparatively large size of the leaves and the great length of the internodes and by the long and narrow, rather lax spikes. The shortness of the spur at the base of the lower theca and the glabrous ovary are also noteworthy features. 64. Rungia Nees. The taxonomie 'P0sition of the -genus Rungia Nees was discussed by me at some length at an earlier occasion (in Boissiera VII, p. 200, 1943), and as since then no new facts bearing on this question have come to light, I will not revert to it. Notwithstanding the similarity in the structure of the fruit, the genus proved to be but distantly related to Dicliptera Juss., whereas it shows an unmistakable affinity to Rostellularia Reiehenb.
NOTES ON THE ACANTHACEAE OF JAVA 73 Rungia is represented in Java by the following species: 1. R. rungiodes (O.Ktze) Backer (Ecbolium O.Ktze; syn.: Dicliptera coerulea BI. var. a BI.; Rungia salaccensis Val.; R. silvatica Hochr. ); 2. R. saranganensis Brem. n. spec. (v. infra); 3. R. blumeana Val.; 4. R. chamaedryoides Brem. n. spec. (v. infra); 5. R. smeruensis Brem. n. spec. (v. infra); 6. R. coerulea (BI.) Warb. (Justicia et postea Dicliptera Bl.); 7. R. parviflora (Retz.) Nees (Justicia Retz.) and 8. R. pectinata (L.) Nees (Justicia L.). The two last-named species are apparently adventitious weeds. R. parviflora was collected long ago near Linga Djati in the Cheribon Residency by BLUME and recorded by him (Bijdr. FI. Ned. Ind .• p. 790. 1826) under the n'ame ]usticia pectinata. NEEs saw that this was 'a false identification. but he himself overlooked the identity of BLuME's specimens with R. parviflora. and referred them together with some other specimens which VALET{)N afterwaros removed to his R. blumeana. to a new species which he called R. origanoides: the latter. therefore. is to be considered a "nomen confusum". R. parviflora is indigenous in the northern provinces of India and Burma. and has since the days of BLuME never again been collected in Java. so that th ere is good reason to regard BLUME's specimens as adventitious. R. parviflora belongs to a group of species which are sa nearly related that CLARKE (in HOOK.F .• FI. Brit. Ind. IV. p. 550. 1885) regarded ,them as conspecific. but although the differences are smalt they are by na means negligible: R. parviflora. e.g .• differs from the other species belonging to thisgroup in the small size of the bracts. R. pectinata has in more recent times repeatedly been found on the lawns of the Botanical Garden. Buitenzorg. but not yet outside the precincts of the Garden. NEES referred to this species a specimen collected by JUNGHUHN. but this was a misidentification. for the latter belongs to R. blumeana Val. var. hirsuta Val. A species notmentioned in the list given above. is R. sarmentosa (NEEs) Val. (in Ic. Bogor. III. tab. 257. 1908). based on Rostellularia sarmentosa Nees (in DC .• Prodr. XI. p. 370. 1847). The latter was founded by NEEs on a specimen collected by ZOLLINGER (n. 596). which according to HALLJER (in Bull. Herb. Boiss. VI. p. 612. 1898) is conspecific with a specimen collected by FORBES (n. 224). VALETON l.c. suggested that both specimens might have been collected in the Buitenzorg Botanical Garden. but this supposition is wrong: FORBEs 224 was. according to S. MOORE (in Journ. of Bot. LXIII. Suppl. p. 79. 1925) collected in the Bantam Residency near Kosala at an altitude of 100 m. In the Leiden Herbarium there are two sterile specimens both collected by BAKHUIZEN V. D. BRINK in the vicinity of Buitenzorg at an altitude of 300-350 m. one near Tjiomas (n. 2296) and the other at Karang Teng'ah (n. 6215). which the collector. probably by comparison with the specimen of FORBES on which VALETON l.c. has based his description. identified as R. sarmentosa. As I myself have seen neither flowers nor fruits. 1 am unable to express a defi-
