This seems to be a rare plant. I have never my- 

 self met with it, and have only seen specimens from 

 Mysore. The one selected for representation is small, 

 but seems specifically identical with those from 

 which Nees' character and description are takem 

 It appears a low, herbaceous annual, very ramous 

 at the base. Branches at first leafy, each ending 

 in a longish spike ; on the leading shoot the spikes 

 are axillary. 



1489. Htgrophilla obovata (Nees), stem her- 

 baceous, erect: cauline leaves oblong, those of the 

 branches obovate, obtuse, attenuated into the petiol, 

 entire, slightly hirsute on both sides: flowers half 

 verticelled: calyx 5-fid, the segments and the in- 

 ferior lip of the corolla bearded. 



Malabar, flowering during the rainy season, also 

 Mergui and Malacca. 



I have not an authentic specimen of this species, 

 so that I am not quite certain of this being Nees' 

 plant. 



He divides the genus into two sections L "Ver- 

 ticillis florum completis," and 2. "Verticillis dimidia- 

 tis," and refers H. ohovata to the second. The 

 specimen represented seems to unite the two sec- 

 tions, having the whorls both complete and dimidi- 

 ate. In otiier respects it seems to accord well with 

 the character. My specimens from Mergui, whence 

 Nees had his, correspond with the Malabar plant 



1490. HrGROPHiLA sALiciFOLiA (Necs), stem 

 herbaceous, erect, roughish round the joints: leaves 

 lanceolate, acuminate at both ends, lineolate, hirsute 

 on the veins beneath: whorls dimidiate: segments 

 of the calyx subulate, hairy. 



Quilon? the station whence the specimens were 

 obtained is not marked, but I believe Quilon is the 

 place. The figure and analysis sufficiently show 

 the forms of the parts, but not so clearly the peculi- 

 arity described by the term lineolate^ '^Omnia folia 

 supra densissime lineolata et obsolete punctata." 

 These "lineoles" are a number of closely appressed 

 white lines, resembling hairs, but which adhere to 

 the surface, and are covered by the epidermis. How 

 they are produced it is difficult to say, but that they 



^ My original specimen of H. polysperma is so 

 imperfect that I can scarcely identify it as the 

 same with the one represented, though I consider 

 them the same. I have adverted to the circum- 

 stance in consequence of Nees describing the 

 spikes as "semipollicares pollicares," while m my 

 specimens they are two or three inches long. 



I am not sure that I perfectly understand his 

 description of the stamens, but if I have not mis- 

 understood him it does not quite agree with my 

 figure beyond the circumstance of there being 2 

 short sterile filaments. His words are "Stamina 

 tubo infero inserta: filamenta basin versus ab altero 

 latere membranacea, et ubi contrahuntur rudimen- 

 tum alterius filamenti breve setaceum hirtum exser- 

 entia." The structure, as shown in the drawing, is 

 the same as in many species of Strobilanthes, Gold- 

 fussea, &c., with the exception of the short filaments 

 being sterile, in place of antheriferous. 



1493. Physichilus Serpyllum (Nees), stem dif- 

 fuse, creeping: leaves strigoso-hirsute, the stem ones 

 sub-orbiculate, the floral oblong, or oblong lanceo- 

 late: upper lip of the corolla bifid, lower acutely 

 3-toothed. 



Bombay. I am indebted to Mr. Law for the 

 specirnen here represented. I have never myself 

 met with the growing plant, and suspect it is rather 

 rare or confined to certain localities. Nees had 

 specimens from both Bombay and Mysore, the 

 former collected by Mr. Law, the latter by Captain 

 Campbell. 



1494. Gymnostachtum polyanthum (R. W.), 

 flowers fascicled on the raceme; fascicles sub-ap- 

 proximate, many-floweredy short, peduncled: pedi- 

 cels bibracteolate : leaves petioled, sub-rotundo- 

 cordate, glabrous, elineolate on both sides: autiiers 

 oval, ecalcarate: stem and calyx glabrous. 



Coorg. I am indebted to Mr. Jerdoij for my 

 specimens of this plant. 



It seems nearly allied to G?. Ceylanica, being hke 

 it sub-acauline, the leaves nearly all radical, and the 



are not hairs is easily shown by subjecting them to fl\377"Z,' i";^ ^" '^'''f '' ^"^ ^T

 though on so small a scale that it requires the aid

 Hygrophila are provided with them as well as many 

 other genera of this order. 



1491. EuYTHRACAivTHus OBTusus (Necs), leaves 

 oblong, obtuse at both ends, the costae, stem and 

 petiob pubescenti-hirtous: racemes axillary and ter- 

 minal, compound, equalling the leaves : stem creep- 

 ing at the base. 



Mergui. For the specimen here represented I 

 am indebted to the late Mr. Griffith, who seems to 

 be the only person who has yet found the plant. It 

 is not in the best state for representation being 

 somewhat too young to give a satisfactory idea of 

 the inflorescence and fi:uctification- 



1492. Hemiadelphis polysperma (Nees), stem 



repent: leaves elliptic-oblong, glabrous: spikes on 



both branches and ramuli terminal: bracts obovate 

 or oval, rough. 



Mergui. Grifiith. 



lar, glabrous, elineolate leaves. Leaves deep green 

 above, pale, almost whitish and strongly marked 

 with prominent veins beneath. Rachis furrowed, 

 glabrous: fascicles of flowers compact, pedicels 

 short, with 2 minute bracteoles at the base. Calyx 

 glabrous, segments subulate. Corolla much longer 

 than the calyx, two-lipped, upper lip two- under 

 three-cleft; tube hairv within. Capsule nearly as 

 long as the corolla, slender, twelve-seeded. Seeds 

 hairy. 



1495. Crtptophragmium canscens (Nees), spikes 

 axillary, passing into terminal bifid ; secund-flowered, 

 glanduloso-hirsute ; leaves ovate, acutish, cuneform 

 at the base, repand, pubescent: capsule twice the 

 length of the setaceous calyx. 



Courtallum. Flowering August and September. 

 Nees contrasts this with C. serrulatumy and considers 

 the two plants quite distinct As I have not seen 

 authentic specimens, I cannot dispute the justice of 

 his decision, but so far as description enables me to 

 judge, I suspect thev will be found too nearly allied.
