ADDITIONS AND CORRECTIONS. 

 LOBELIACE^E. 



The following are additions and corrections to the generic characters of this 

 order, on p. 2 : 



I. NEMACLADUS. Filaments either partly or almost wholly monadelphous. Seeds oval 

 or globular, obscurely costate or striate longitudinally and somewhat favose or transversely 

 reticulate between the ribs. 



I I . PARISHELLA. Calyx 5-cleft, with campanulate tube wholly adnate to the ovary and 

 shorter than the spatulate foliaceous lobes. Corolla almost rotate, shorter than the calyx, 

 deeply and nearly equally 5-cleft. Stamens free from the corolla : filaments distinct at base 

 only, above connate into a slender tube with inflexed summit. Style filiform : stigma de- 

 pressed-capitate, 2-lobed, not annulate. Capsule turbinate, inferior, except the low-conical 

 apex, which is circumscissile close to the base of the calyx-lobes and falls off as a lid. Seeds 

 globose, smooth and nearly even. Otherwise nearly as Nemucladus. 



I 2 . HOWELLIA. (Under tribe Lobeliea'.) Flowers of two forms ; the emersed corolliferous, 

 submersed with undeveloped corolla. Calyx with linear-clavate tube adnate for its whole 

 length to the ovary, and a limb of five nearly equal slender-subulate or filiform segments. 

 Corolla even iu emersed flowers not surpassing the calyx ; its very short tube divided nearly 

 to base on the (apparently) upper side ; lobes oblong, almost equal, three united higher. 

 Stamen-tube nearly free, and with the included style slightly incurved : anthers oval ; two 

 smaller trisetulose, three larger naked. Ovary strictly one-celled, with two filiform parietal 

 placentae, each 3-5-ovulate. Upper ovules ascending ; lower pendulous. Capsule clavate- 

 obloug or fusiform, with contracted apex, membranaceous at maturity and bursting irregu- 

 larly on one side. Seeds few and large, linear-oblong, smooth, callous-apiculate at the 

 chalaza. Aquatic herb. 



1. NEMACLADUS, Nutt. Genus now increased in number of species 

 and forms. 



N. ramosissimus, NUTT., p. 3. Rarely a little puberuleut : filaments usually monadel- 

 phous for most of their length, sometimes separating below in age. Nuttall's original is 

 the more slender and verv diffuse form, most abundant in Lower California, W. Arizona, 

 and S. W. Utah, with very small white corolla little surpassing the calyx, and roundish seeds. 

 N. tenuisslmus and N. capillaris, Greene, Bull. Calif. Acad. i. 198. 196. 



Var. pinnatifidus ( A T . pinnatifidnK, Greene, 1. c.) is less diffuse and has the (glabrous) 

 radical leaves irregularly pinnatifid, and their small lobes commonly 1-2-toothed. 

 Sierra Madre Mountains, Los Angeles Co., 0. D. Allen. (All Saints' Bay, Lower Cali- 

 fornia, Greene.) 



Var. montanus (N. montanus and N. rubescens, Greene, 1. c.). More erect, a span or 

 two high, with larger flowers and fruit, on less divaricate or ascending pedicels : column more
