Campylogramma lancifolia, v. A. v. R., Bull. Btz., 1916, XXIIl, 

 7, tab. 1; Mai. Ferns & All., Supplem. 1, 334. 



Since the plants cultivated in the Buitenborg Gardens, on which the 

 description of this species is based, have become older, it proves that the 

 stipes are articulated to the rhizome, a fact not to be seen in young 

 plants even when dried. It is therefore rather evident that the genus 

 Campylogramma (as far as regards this species, the rhizome and base of 

 the stipes of C. pteridiformis v. A. v. R. being still unknown) is related 

 to the genus Pleopeltis § Pleuridium and this species to PI. Zollingeriaua 

 V. A. V. R. {= Polypodium heterocarpum BL, Flor. Jav , 11, 167, tab. LXXV). 



I am unable to examine which of both species may probably have been 

 the ancestor or descendant of the other or that they are both descendants 

 of a common ancestor. While the knowledge of the often easily recognizable 

 affiniiy between genera and species is very valuable for their systematical 

 grouping, I think the tracking of their probable or apodictically pretended 

 descent, which depends as a rule only on not to be proved suppositions 

 or personal conceptions, is too trifling and the mention of it too worthless 

 to take it into consideration for systematic-botanical publications. 



Cyathea crenulata, Bi., Enum. PI. Jav., 11, 244; v. A. v. R., Mai. Ferns 

 21; Supplem., 27. 488, and Corr. 



Forma latissima: Like forma squamulosa (includ. forma asperula) but 

 the largest pinnulae 2 — 3'/2 cm. broad at the base; at least the lower 

 tertiary segments conspicuously remote. — Java (Mt. Kawi, .Arens). 



Cyathea tuberculata, v. A. v. R. 



Stipites in sicco sursum cum rachidibus rufo-fusci, deorsum atro- 

 castanei, ubique squamosi, squamis longis, lanceolato-subulatis, ferrugineo- 

 fuscis, graciliter eroso-laceratis, basibus persistentibus, inferioribus tuber- 

 culiformibus, superioribus punctiformibus. Frondes profunde 3-pinnatipartitae; 

 rachides supra castaneo-hirsuto-tomentosae, subtus decidue ferrugineo-crispato- 

 pilosae, indumento squamis copiose intermixto; squamae squamis sti pi tis similes 

 sed superiores seiisim minores, sat integerrimae, basi persistente, punctiformi. 

 Pinnae petiolatae, lineari-oblongae, + 25 — 35 cm. longae et 10 cm. latae, abrupte 

 acuminatae. Pinnulae subcoriaceae, glabrae, confertae, sessiles, subhorizontales, 

 lineares, maximae + 5 — 5'/2 cm. longae et 1 — l'/4 cm. latae, basi rotun- 

 dato-truncatae, margine fere ad costam incisae, apice obtuso angustatae vel 

 breviter acuminatae; pinnae inferiores paullo abbreviatae ; costae supra basin 

 versus hirsutae, subtus squamulis ovatis, bullatis, ferrugineis, acuminatis 

 copiose munitae. Lobi subconferti, subhorizontales, lineari-oblongi, subfalcati, 

 2 — 2'/2 mm. lati, obtusi, integerrimi; costulae subtus basin versus buliato- 

 squamulosi; venae usque ad 8 — 10 utrinque, furcatae, superiores simplices.
